Chapter 6: Installation Installing CMM4 Page 6-64 Installing CMM4 Note For instructions on CMM3 (CMMmicro) or CMM4 installation, including the outdoor temperature range in which it is acceptable to install the unit, tools required, mounting and cabling instructions, and connectivity verification, please see the PMP Synchronization Solutions User Guide located on the Cambium website. The Cluster Management Module 4 (CMM4) provides power, sync, and network connectivity for up to eight APs, backhauls, and Ethernet terrestrial feeds in a variety of configurations. The CMM4 provides  Sync over Power over Ethernet and integrated surge suppression on the controller board for up to 8 APs or BHs. Both a custom 30 VDC power scheme and a custom 56 VDC power scheme are available. Neither is the same as the later IEEE Standard 802.3af, and neither is compatible with it.  Managed switching using a hardened EtherWAN switch (1090CKHH models). The CMM4 ships with a 14-port EtherWAN switch and is also available without a switch. The CMM4 originally shipped with a 9-port EtherWAN switch.  Surge suppression on the controller board for the incoming 30V DC and 56V DC power lines and GPS coax cable.  Auto-negotiation on the Ethernet ports. Ports will auto-negotiate to match inputs that are either 100Base-T or 10Base-T, and either full duplex or half duplex, when the connected device is set to auto-negotiate. Alternatively, these parameters are settable.  An always-on NTP (Network Time Protocol) server that can provide date and time to any radio that can reach the CMM’s management IP address.  CNUT can be used to upgrade the CMM-4 software. 450 Series and 450i Series can use the CMM4’s EtherWan switch for their network connectivity. Note The 56 V of a CMM4 needs to go through the adapter cable (part number N000045L001A) as shown in Figure 34 on page 2-52. A CMM4 56V power adapter cable can be prepared by swapping pins 5 and 7. See CMM4 56 V power adapter cable pinout on page 2-52 for power adapter cable pinout.
Chapter 6: Installation Supplemental installation information Page 6-65 Supplemental installation information This section contains detailed installation procedures that are not included in the above topics, such as how to strip cables, create grounding points and weatherproof connectors. Stripping drop cable When preparing the drop cable for connection to the 450 Platform Family ODU or LPU, use the following measurements: When preparing the drop cable for connection to the 450 Platform PSU (without a cable gland), use the following measurements:
Chapter 6: Installation Supplemental installation information Page 6-66 Creating a drop cable grounding point Use this procedure to connect the screen of the main drop cable to the metal of the supporting structure using the cable grounding kit (Cambium part number 01010419001). To identify suitable grounding points, refer to Hazardous locations on page 3-15. 1 Remove 60 mm (2.5 inches) of the drop cable outer sheath. 2 Cut 38mm (1.5 inches) of rubber tape (self-amalgamating) and fit to the ground cable lug. Wrap the tape completely around the lug and cable. 3 Fold the ground wire strap around the drop cable screen and fit cable ties.
Chapter 6: Installation Supplemental installation information Page 6-67 4 Tighten the cable ties with pliers. Cut the surplus from the cable ties. 5 Cut a 38mm (1.5 inches) section of self-amalgamating tape and wrap it completely around the joint between the drop and ground cables. 6 Use the remainder of the self-amalgamating tape to wrap the complete assembly. Press the tape edges together so that there are no gaps.
Chapter 6: Installation Supplemental installation information Page 6-68 7 Wrap a layer of PVC tape from bottom to top, starting from 25 mm (1 inch) below and finishing 25 mm (1 inch) above the edge of the self-amalgamating tape, overlapping at half width. 8 Repeat with a further four layers of PVC tape, always overlapping at half width. Wrap the layers in alternate directions (top to bottom, then bottom to top). The edges of each layer should be 25mm (1 inch) above (A) and 25 mm (1 inch) below (B) the previous layer. 9 Prepare the metal grounding point of the supporting structure to provide a good electrical contact with the grounding cable clamp. Remove paint, grease or dirt, if present. Apply anti-oxidant compound liberally between the two metals. 10 Clamp the bottom lug of the grounding cable to the supporting structure using site approved methods. Use a two-hole lug secured with fasteners in both holes. This provides better protection than a single-hole lug.
Chapter 6: Installation Supplemental installation information Page 6-69 Attaching and weatherproofing an N type connector The following procedure should be used to weatherproof the N type connectors fitted to the connectorized ODU (AP/SM/BH) and antenna. This procedure must be followed to ensure that there is no moisture ingress at the radio ports. Failure to properly seal N-type antenna connectors can result in poor link performance or complete loss of radio communication. Note Cambium recommends to assemble the antenna, attach the ODU and cabling, and to seal the RF connections before installing the unit at the deployment site. Note N type connectors should be tightened using a torque wrench, set to 15 lb in or 1.7 Nm. If a torque wrench is not available, N type connectors may be finger tightened. Use this procedure to weatherproof the N type connectors fitted to the connectorized ODU and external antenna (if recommended by the antenna manufacturer). 1 Ensure the connection is tight. A torque wrench should be used if available: 2 Wrap the connection with a layer of 19 mm (0.75 inch) PVC tape, starting 25 mm (1 inch) below the connector body. Overlap the tape to half-width and extend the wrapping to the body of the LPU. Avoid making creases or wrinkles:
Chapter 6: Installation Supplemental installation information Page 6-70 3 Smooth the tape edges: 4 Cut a 125mm (5 inches) length of rubber tape (self-amalgamating): 5 Expand the width of the tape by stretching it so that it will wrap completely around the connector and cable: 6 Press the tape edges together so that there are no gaps. The tape should extend 25 mm (1 inch) beyond the PVC tape:
Chapter 6: Installation Supplemental installation information Page 6-71 7 Wrap a layer of 50 mm (2 inch) PVC tape from bottom to top, starting from 25 mm (1 inch) below the edge of the self-amalgamating tape, overlapping at half width. 8 Repeat with a further four layers of 19 mm (0.75 inch) PVC tape, always overlapping at half width. Wrap the layers in alternate directions:  Second layer: top to bottom.  Third layer: bottom to top.  Fourth layer: top to bottom.  Fifth layer: bottom to top. The bottom edge of each layer should be 25 mm (1 inch) below the previous layer. 9 Check the completed weatherproof connection: Note A video of this procedure can be found at: https://www.youtube.com/watch?v=a-twPfCVq4A

Chapter 7: Configuration Preparing for configuration Page 7-2 Preparing for configuration This section describes the checks to be performed before proceeding with unit configuration and antenna alignment. Safety precautions All national and local safety standards must be followed while configuring the units and aligning the antennas. Warning Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate RF energy as soon as they are powered up. Respect the safety standards defined in Compliance with safety standards on page 4-22, in particular the minimum separation distances. Observe the following guidelines:  Never work in front of the antenna when the ODU is powered.  Always power down the PSU before connecting or disconnecting the drop cable from the PSU, ODU or LPU. Regulatory compliance All applicable radio regulations must be followed while configuring the units and aligning the antennas. For more information, refer to Compliance with radio regulations on page 4-34. Caution If the system designer has provided a list of channels to be barred for TDWR radar avoidance, the affected channels must be barred before the units are allowed to radiate on site, otherwise the regulations will be infringed. Attention Si le concepteur du système a fourni une liste de canaux à interdire pour éviter les radars TDWR, les cannaux concernées doivent être interdits avant que les unités sont autorisées à émettre sur le site, sinon la réglementation peut être enfreinte.

Procedure 13 Entering AP/BHM time setup information 1 Enter the appropriate information in the format shown above. 2 Then click the Set Time and Date button. Note The time displayed at the top of this page is static unless your browser is set to automatically refresh Powering the SM/BHS for test Procedure 14 Powering the SM/BHS for test 1 In one hand, securely hold the top (larger shell) of the SM/BHS. With the other hand, depress the lever in the back of the base cover (smaller shell). Remove the base cover. 2 Plug one end of a CAT 5 Ethernet cable into the SM PSU port 3 Plug the other end of the Ethernet cable into the jack in the pig tail that hangs from the power supply 4 Roughly aim the SM/BHS toward the AP/BHM 5 Plug the power supply into an electrical outlet Warning From this point until you remove power from the AP/BHM, stay at least as far from the AP/BHM as the minimum separation distance specified in Calculated distances and power compliance margins. 6 Repeat the foregoing steps for each SM/BHS that you wish to include in the test.
Chapter 7: Configuration Quick link setup Page 7-20 Viewing the Session Status of the AP/BHM to determine test registration Once the SMs/BHS under test are powered on, return to the computing device to determine if the SM/BHS units have registered to the AP/BHM. Note In order for accurate power level readings to be displayed, traffic must be present on the radio link. The Session Status tab provides information about each SM/BHS that has registered to the AP/BHM. This information is useful for managing and troubleshooting a system. All information that you have entered in the Site Name field of the SM/BHS displays in the Session Status tab of the linked AP/BHM. The Session Status tab also includes the current active values on each SM( or BHS) (LUID) for MIR, and VLAN, as well as the source of these values (representing the SM/BHS itself, Authentication Server, or the AP/BHM and cap, if any—for example, APCAP as shown above).. As an SM/BHS registers to the AP/BHM, the configuration source that this page displays for the associated LUID may change. After registration, however, the displayed source is stable and can be trusted. Idle subscribers may be included or removed from the session status display by enabling or disabling, respectively, the Show Idle Sessions parameter. Enabling or disabling this parameter only affects the GUI display of subscribers, not the registration status. The SessionStatus.xml hyperlink allows user to export session status page from web management interface of AP/BHM. The session status page will be exported in xml file.
Chapter 7: Configuration Quick link setup Page 7-21 Procedure 15 Viewing the AP Session Status page 1 On the AP web management GUI, navigate to Home, Session Status: Figure 127 Session Status tab of AP Note Session status page for BHM is same as AP. 2 Verify that for each SM (or BHS) MAC address (printed on the SM/BHS housing) the AP/BHM has established a registered session by verifying the “State” status of each entry. The Session Status page of the AP/BHM is explained in Table 102.
Chapter 7: Configuration Quick link setup Page 7-22 Table 102 Session Status Attributes – AP Attribute Meaning Show Idle Sessions Idle subscribers may be included or removed from the session status display by enabling or disabling, respectively, the Show Idle Sessions parameter. Enabling or disabling this parameter only affects the GUI display of subscribers, not the registration status. Last Session Counter Reset This field displays date and time stamp of last session counter reset. Last Time Idle SMs Removed This field displays date and time stamp of last Idle SMs Removed. On click of “Remove Idle SMs” button, all the SMs which are in Idle state are flushed out.

Applicable products PMP : AP SM PTP: BHM  BMS To configure the IP interface, follow these instructions: Procedure 16 Configuring the AP/BHM IP interface 1 Select menu option Configuration > IP. The LAN configuration page is displayed: 2 Update IP Address, Subnet Mask and Gateway IP Address to meet network requirements (as specified by the network administrator). 3 Review the other IP interface attributes and update them, if necessary (see Table 103 IP interface attributes). 4 Click Save. “Reboot Required” message is displayed: 5 Click Reboot. The IP page of AP/SM/BHM/BHS is explained in Table 103.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-25 Table 103 IP interface attributes Attribute Meaning IP Address Internet Protocol (IP) address. This address is used by family of Internet protocols to uniquely identify this unit on a network. Subnet Mask Defines the address range of the connected IP network. Gateway IP Address The IP address of a computer on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks. DHCP state If Enabled is selected, the DHCP server automatically assigns the IP configuration (IP address, subnet mask, and gateway IP address) and the values of those individual parameters (above) are not used. The setting of this DHCP state parameter is also viewable (read only), in the Network Interface tab of the Home page. DNS IP Address Canopy devices allow for configuration of a preferred and alternate DNS server IP address either automatically or manually. Devices must set DNS server IP address manually when DHCP is disabled for the management
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-26 interface of the device. DNS servers may be configured automatically from the DHCP response when DHCP is enabled for the management interface of the device. Optionally devices may be configured to set the DNS server IP address manually when DHCP is enabled for the management interface. The default DNS IP addresses are 0.0.0.0 when configured manually. Preferred DNS Server The first address used for DNS resolution. Alternate DNS Server If the Preferred DNS server cannot be reached, the Alternate DNS Server is used. Domain Name The operator’s management domain name may be configured for DNS. The domain name configuration can be used for configuration of the servers in the operator’s network. The default domain name is example.com, and is only used if configured as such. Advanced LAN1 IP Configuration – Default alternate LAN1 IP address Hardcoded default alternate IP address (169.254.1.1) that is available only when connected to the Ethernet port. When enabled, user can configure a second IP address for the bridge which is other than the hardcoded IP address (169.254.1.1).

Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-28 NAT, DHCP Server, DHCP Client and DMZ Applicable products PMP : SM The system provides NAT (Network Address Translation) for SMs in the following combinations of NAT and DHCP (Dynamic Host Configuration Protocol):  NAT Disabled  NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP Server  NAT with DHCP Client(DHCP selected as the Connection Type of the WAN interface)  NAT with DHCP Server  NAT without DHCP NAT NAT isolates devices connected to the Ethernet or wired side of a SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic (separate from its address for management), terminates transport traffic and allows you to assign a range of IP addresses to devices that are connected to the Ethernet or wired side of the SM. In the Cambium system, NAT supports many protocols, including HTTP, ICMP (Internet Control Message Protocols), and FTP (File Transfer Protocol). For virtual private network (VPN) implementation, L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) and PPTP (Point to Point Tunneling Protocol) are supported. Note When NAT is enabled, a reduction in throughput is introduced in the system (due to processing overhead). DHCP DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the Cambium system. In conjunction with the NAT features, each SM provides the following:  A DHCP server that assigns IP addresses to computers connected to the SM by Ethernet protocol.  A DHCP client that receives an IP address for the SM from a network DHCP server. DMZ In conjunction with the NAT features, a DMZ (Demilitarized Zone) allows the allotment of one IP address behind the SM for a device to logically exist outside the firewall and receive network traffic. The first three octets of this IP address must be identical to the first three octets of the NAT private IP address.  A DHCP server that assigns IP addresses to computers connected to the SM by Ethernet protocol.  A DHCP client that receives an IP address for the SM from a network DHCP server.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-29 NAT Disabled The NAT Disabled implementation is illustrated in Figure 128. Figure 128 NAT disabled implementation NAT with DHCP Client and DHCP Server The NAT with DHCP Client and DHCP server is illustrated in Figure 129.

Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-32 NAT and VPNs VPN technology provides the benefits of a private network during communication over a public network. One typical use of a VPN is to connect employees remotely (who are at home or in a different city), with their corporate network through a public Internet. Any of several VPN implementation schemes is possible. By design, NAT translates or changes addresses, and thus interferes with a VPN that is not specifically supported by a given NAT implementation. With NAT enabled, SM supports L2TP over IPSec (Level 2 Tunneling Protocol over IP Security) VPNs and PPTP (Point to Point Tunneling Protocol) VPNs. With NAT disabled, SM supports all types of VPNs.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-33 IP interface with NAT disabled - SM The IP page of SM with NAT disabled is explained in Table 106. Table 106 IP attributes - SM with NAT disabled Attribute Meaning IP Address Enter the non-routable IP address to associate with the Ethernet connection on this SM. (The default IP address from the factory is 169.254.1.1.) If you forget this parameter, you must both:  physically access the module.  use recovery mode to access the module configuration parameters at 169.254.1.1. See Radio recovery mode on page 1-26 Note Note or print the IP settings from this page. Ensure that you can readily associate these IP settings both with the module and with the other data that you store about the module. Network Accessibility Specify whether the IP address of the SM must be visible to only a device connected to the SM by Ethernet (Local) or be visible to the AP/BHM as well (Public). Subnet Mask Enter an appropriate subnet mask for the SM to communicate on the network. The default subnet mask is 255.255.0.0. Gateway IP Address Enter the appropriate gateway for the SM to communicate with the network. The default gateway is 169.254.0.0. DHCP state If you select Enabled, the DHCP server automatically assigns the IP configuration (IP address, subnet mask, and gateway IP address) and the values of those individual parameters (above) are not used. The setting of this DHCP state parameter is also viewable, but not settable, in the Network Interface tab of the Home page. In this tab, DHCP State is settable only if the Network Accessibility parameter in the IP tab is set to Public. This parameter is also settable in the NAT tab of the Configuration web page, but only when NAT is enabled.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-34 If the DHCP state parameter is set to Enabled in the Configuration > IP sub-menu of the SM/BHS, do not check the BootpClient option for Packet Filter Types in its Protocol Filtering tab, because doing so can block the DHCP request. (Filters apply to all packets that leave the SM via its RF interface, including those that the SM itself generates.) If you want to keep DHCP enabled and avoid the blocking scenario, select the Bootp Server option instead. This will result in responses being appropriately filtered and discarded. DHCP DNS IP Address Canopy devices allow for configuration of a preferred and alternate DNS server IP address either automatically or manually. Devices must set DNS server IP address manually when DHCP is disabled for the management interface of the device. DNS servers may be configured automatically from the DHCP response when DHCP is enabled for the management interface of the device. Optionally devices may be configured to set the DNS server IP address manually when DHCP is enabled for the management interface. The default DNS IP addresses are 0.0.0.0 when configured manually. Preferred DNS Server The first DNS server used for DNS resolution. Alternate DNS Server The second DNS server used for DNS resolution. Domain Name The operator’s management domain name may be configured for DNS. The domain name configuration can be used for configuration of the servers in the operator’s network. The default domain name is example.com, and is only used if configured as such.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-35 IP interface with NAT enabled - SM The IP page of SM with NAT enabled is explained in Table 107. Table 107 IP attributes - SM with NAT enabled Attribute Meaning IP Address Assign an IP address for SM/BHS management through Ethernet access to the SM/BHS. Set only the first three bytes. The last byte is permanently set to 1. This address becomes the base for the range of DHCP-assigned addresses. Subnet Mask Assign a subnet mask of 255.255.255.0 or a more restrictive subnet mask. Set only the last byte of this subnet mask. Each of the first three bytes is permanently set to 255.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-36 NAT tab with NAT disabled - SM The NAT tab of SM with NAT disabled is explained in Table 108. Table 108 NAT attributes - SM with NAT disabled
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-37 Attribute Meaning NAT Enable/Disable This parameter enables or disables the Network Address Translation (NAT) feature for the SM. NAT isolates devices connected to the Ethernet or wired side of a SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic separate from its address for management, terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet or wired side of the SM. When NAT is enabled, VLANs are not supported on the wired side of that SM. You can enable NAT in SMs within a sector where VLAN is enabled in the AP/BHM, but this may constrain network design. IP Address This field displays the IP address for the SM. DHCP Server will not automatically assign this address when NAT is disabled. Subnet Mask This field displays the subnet mask for the SM. DHCP Server will not automatically assign this address when NAT is disabled. Gateway IP Address This field displays the gateway IP address for the SM. DHCP Server will not automatically assign this address when NAT is disabled. ARP Cache Timeout If a router upstream has an ARP cache of longer duration (as some use 30 minutes), enter a value of longer duration than the router ARP cache. The default value of this field is 20 minutes. TCP Session Garbage Timeout Where a large network exists behind the SM, you can set this parameter to lower than the default value of 120 minutes. This action makes additional resources available for greater traffic than the default value accommodates. UDP Session Garbage Timeout You may adjust this parameter in the range of 1 to 1440 minutes, based on network performance. The default value of this parameter is 4 minutes. Translation Table Size Total number of minutes that have elapsed since the last packet transfer between the connected device and the SM/BHS. Note When NAT is disabled, the following parameters are not required to be configurable: WAN Inter face > Connection Type, IP Address, Subnet Mask, Gateway IP address LAN Interface > IP Address LAN DHCP Server > DHCP Server Enable/Disable, DHCP Server Lease Timeout, Number of IP’s to Lease, DNS Server Proxy, DNS IP Address, Preferred DNS IP address, Alternate DNS IP address Remote Management Interface > Remote Management Interface, IP address, Subnet Mask, DHCP DNS IP Address, Preferred DNS Server, Alternate DNS Server, Domain Name NAT Protocol Parameters > ARP Cache Timeout, TCP Session Garbage Timeout, UDP Session Garbage Timeout, Translation Table Size
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-38 NAT tab with NAT enabled - SM The NAT tab of SM with NAT enabled is explained in Table 109. Table 109 NAT attributes - SM with NAT enabled
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-39 Attribute Meaning NAT Enable/Disable This parameter enables or disabled the Network Address Translation (NAT) feature for the SM. NAT isolates devices connected to the Ethernet or wired side of a SM from being seen directly from the wireless side of the SM. With NAT enabled, the SM has an IP address for transport traffic separate from its address for management, terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet or wired side of the SM. When NAT is enabled, VLANs are not supported on the wired side of that SM. You can enable NAT in SMs within a sector where VLAN is enabled in the AP, but this may constrain network design. WAN Interface The WAN interface is the RF-side address for transport traffic. Connection Type This parameter may be set to Static IP—when this is the selection, all three parameters (IP Address, Subnet Mask, and Gateway IP Address) must be properly populated. DHCP—when this is the selection, the information from the DHCP server configures the interface. PPPoE—when this is the selection, the information from the PPPoE server configures the interface. Subnet Mask If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the subnet mask of the SM for RF transport traffic. Gateway IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the gateway IP address for the SM for RF transport traffic. Reply to Ping on WAN Interface By default, the radio interface does not respond to pings. If you use a management system (such as WM) that will occasionally ping the SM, set this parameter to Enabled. LAN Interface The LAN interface is both the management access through the Ethernet port and the Ethernet-side address for transport traffic. When NAT is enabled, this interface is redundantly shown as the NAT Network Interface Configuration on the IP tab of the Configuration web page in the SM. IP Address Assign an IP address for SM/BHS management through Ethernet access to the SM. This address becomes the base for the range of DHCP-assigned addresses. Subnet Mask Assign a subnet mask of 255.255.255.0 or a more restrictive subnet mask. Set only the last byte of this subnet mask. Each of the first three bytes is permanently set to 255. DMZ Enable Either enable or disable DMZ for this SM/BHS.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-40 DMZ IP Address If you enable DMZ in the parameter above, set the last byte of the DMZ host IP address to use for this SM when DMZ is enabled. Only one such address is allowed. The first three bytes are identical to those of the NAT private IP address. Ensure that the device that receives network traffic behind this SM is assigned this address. The system provides a warning if you enter an address within the range that DHCP can assign. DHCP Server This is the server (in the SM) that provides an IP address to the device connected to the Ethernet port of the SM. DHCP Server Enable/Disable Select either Enabled or Disabled. Enable to:  Allow this SM to assign IP addresses, subnet masks, and gateway IP addresses to attached devices.  Assign a start address for DHCP.  Designate how many IP addresses may be temporarily used (leased). Disable to:  Restrict SM/BHS from assigning addresses to attached devices. DHCP Server Lease Timeout Based on network performance, enter the number of days between when the DHCP server assigns an IP address and when that address expires. The range of values for this parameter is 1 to 30 days. The default value is 30 days. DHCP Start IP If you enable DHCP Server below, set the last byte of the starting IP address that the DHCP server assigns. The first three bytes are identical to those of the NAT private IP address. Number of IPs to Lease Enter how many IP addresses the DHCP server is allowed to assign. The default value is 50 addresses. DNS Server Proxy This parameter enables or disables advertisement of the SM/BHS as the DNS server. On initial boot up of a SM with the NAT WAN interface configured as DHCP or PPPoE, the SM module will not have DNS information immediately. With DNS Server Proxy disabled, the clients will renew their lease about every minute until the SM has the DNS information to give out. At this point the SM will go to the full configured lease time period which is 30 days by default. With DNS Server Proxy enabled, the SM will give out full term leases with its NAT LAN IP as the DNS server. DNS IP Address Select either: Obtain Automatically to allow the system to set the IP address of the DNS server or Set Manually to enable yourself to set both a preferred and an alternate DNS IP address. Preferred DNS IP Address Enter the preferred DNS IP address to use when the DNS IP Address parameter is set to Set Manually.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-41 Alternate DNS IP Address Enter the DNS IP address to use when the DNS IP Address parameter is set to Set Manually and no response is received from the preferred DNS IP address. Remote Management Interface To offer greater flexibility in IP address management, the NAT-enabled SM’s configured WAN Interface IP address may now be used as the device Remote Management Interface (unless the SM’s PPPoE client is set to Enabled) Disable: When this interface is set to “Disable”, the SM is not directly accessible by IP address. Management access is only possible through either the LAN (Ethernet) interface or a link from an AP web page into the WAN (RF-side) interface. Enable (Standalone Config): When this interface is set to “Enable (Standalone Config)”, to manage the SM/BHS the device must be accessed by the IP addressing information provided in the Remote Configuration Interface section. Note When configuring PPPoE over the link, use this configuration option (PPPoE traffic is routed via the IP addressing specified in section Remote Configuration Interface). Enable (Use WAN Interface): When this interface is set to “Enable (Use WAN Interface)”, the Remote Configuration Interface information is greyed out, and the SM is managed via the IP addressing specified in section WAN Interface). Note When using this configuration, the ports defined in section Configuration, Port Configuration are consumed by the device. For example, if FTP Port is configured as 21 by the SM, an FTP server situated below the SM must use a port other than 21. This also applies to DMZ devices; any ports specified in section Configuration, Port Configuration will not be translated through the NAT, they is consumed by the device’s network stack for management. Connection Type This parameter can be set to: Static IP—when this is the selection, all three parameters (IP Address, Subnet Mask, and Gateway IP Address) must be properly populated. DHCP—when this is the selection, the information from the DHCP server configures the interface. IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the IP address of the SM for RF management traffic. Subnet Mask If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the subnet mask of the SM for RF management traffic.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-42 Gateway IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the gateway IP address for the SM for RF management traffic. Note or print the IP settings from this page. Ensure that you can readily associate these IP settings both with the module and with the other data that you store about the module. DHCP DNS IP Address Select either: Obtain Automatically to allow the system to set the IP address of the DNS server. or Set Manually to enable yourself to set both a preferred and an alternate DNS IP address. Preferred DNS Server Enter the preferred DNS IP address to use when the DNS IP Address parameter is set to Set Manually. Alternate DNS Server Enter the DNS IP address to use when the DNS IP Address parameter is set to Set Manually and no response is received from the preferred DNS IP address. Domain Name Domain Name to use for management DNS configuration. This domain name may be concatenated to DNS names used configured for the remote configuration interface. ARP Cache Timeout If a router upstream has an ARP cache of longer duration (as some use 30 minutes), enter a value of longer duration than the router ARP cache. The default value of this field is 20 (minutes). TCP Session Garbage Timeout Where a large network exists behind the SM, you can set this parameter to lower than the default value of 120 (minutes). This action makes additional resources available for greater traffic than the default value accommodates. UDP Session Garbage Timeout You may adjust this parameter in the range of 1 to 1440 minutes, based on network performance. The default value of this parameter is 4 (minutes).
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-43 NAT DNS Considerations - SM SM DNS behavior is different depending on the accessibility of the SM. When NAT is enabled the DNS configuration that is discussed in this document is tied to the RF Remote Configuration Interface, which must be enabled to utilize DNS Client functionality. Note that the WAN DNS settings when NAT is enabled are unchanged with the addition of the management DNS feature discussed in this document.

Table 111 NAT Port Mapping attributes - SM Attribute Meaning Port Map 1 to 10 Separate parameters allow you to distinguish NAT ports from each other by assigning a unique combination of port number, protocol for traffic through the port, and IP address for access to the port
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-44 DHCP – BHS Applicable products PTP: BHM DHCP enables a device to be assigned a new IP address and TCP/IP parameters, including a default gateway, whenever the device reboots. Thus DHCP reduces configuration time, conserves IP addresses, and allows modules to be moved to a different network within the Cambium system. In conjunction with the NAT features, each BHS provides:  A DHCP server that assigns IP addresses to computers connected to the BHS by Ethernet protocol.  A DHCP client that receives an IP address for the BHS from a network DHCP server. Reconnecting to the management PC If the IP Address, Subnet Mask and Gateway IP Address of the unit have been updated to meet network requirements, then reconfigure the local management PC to use an IP address that is valid for the network. See Configuring the management PC on page 7-3. Once the unit reboots, log in using the new IP address. See Logging into the web interface on page 7-5. VLAN configuration for PMP Applicable products PMP : AP SM VLAN Remarking VLAN Remarking feature allows the user to change the VLAN ID and priority of both upstream and downstream packets at the Ethernet Interface. The remarking configuration is available for: 1. VLAN ID re-marking 2. 802.1p priority re-marking Note For Q-in-Q VLAN tagged frame, re-marking is performed on the outer tag.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-45 VLAN ID Remarking SM supports the ability to re-mark the VLAN ID on both upstream and downstream VLAN frames at the Ethernet interface. For instance, a configuration can be added to re-mark VLAN ID ‘x’ to VLAN ID ‘y’ as shown in Table 112. AP does not support VLAN ID remarking. Table 112 VLAN Remarking Example VLAN frame direction Remarking Upstream SM receives VLAN ID ‘x’ frame at the Ethernet interface, checks the configuration and re-marks to VLAN ID ‘y’. So VLAN ID ‘y’ frame comes out of AP’s Ethernet interface. When SM re-marks, a dynamic entry in VLAN membership table for ‘y’ is added to allow reception of VLAN ID ‘y’ downstream packet. Downstream AP receives VLAN ID ‘y’ frame at the Ethernet interface and sends to SM. SM accepts the frame as it has an entry in the membership table and re-marks to VLAN ID ‘x’. This reverse re- marking is necessary because the downstream devices do not know of re-marking and are expecting VLAN ‘x’ frames. This remarking is done just before sending the packet out on Ethernet interface. 802.1P Remarking AP/BHM and SM/BHS allow re-marking of 802.1p priority bits for the frames received at the Ethernet interface. Priority bits are not re-marked for the packets sent out of Ethernet interface (reverse direction). Configuration must be added at SM/BHS for upstream frames and at AP/BHM for downstream frames. VLAN Priority Bits configuration VLAN Priority Bits Configuration feature allows the user to configure the three 802.1p bits upon assigning VLAN to an ingress packet. The priority bits configuration is available for:  Default Port VID  Provider VID  MAC Address mapped Port VID  Management VID Default Port VID This VID is used for untagged frames and will correspond to the Q-Tag for 802.1Q frames (if VLAN Port Type is Q), or the C-Tag for 802.1ad frames (if the VLAN Port Type is QinQ). The priority bits used in the Q-tag/C-tag are configurable. The configuration can be:  Promote IPv4/IPv6 priority – The priority in the IP header is copied to the Q-tag/C-tag.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-46  Define priority – Specify the priority in the range of 0 to 7. This value is used as priority in the Q-tag/C-tag. MAC Address Mapped VID If a packet arrives at the SM/BHS that is sourced from a device whose MAC address is in the table, then the corresponding VID is used for that frame’s Q-tag (Q port) or C-tag (QinQ port). The priority bits used in the Q-tag/C-tag are configurable similar to default port VID. Provider VID The provider VID is used for the S-tag. The priority bits used in the S-tag are configurable similar to default port VID. Provider VID has an extra priority configuration:  Copy inner tag 802.1p priority – The priority in the C-tag is copied to the S-tag. Management VID This VID is used to communicate with AP/BHM and SM/BHS for management purposes. The priority bits used in the Q-tag are configurable similar to default port VID. Use AP’s Management VID for ICC connected SM This feature allows the SM to use the AP’s management VLAN ID when the SM is registered to the AP via ICC. This feature is useful for the customer who uses a different management VID for the SM and AP and Zero Touch feature is enabled for configuration. This parameter may be accessed via the Configuration > VLAN page on the AP’s web management interface.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-47 VLAN page of AP The VLAN tab of the AP/BHM is explained in Table 113. Table 113 AP/BHM VLAN tab attributes Attribute Meaning VLAN Specify whether VLAN functionality for the AP and all linked SMs must (Enabled) or may not (Disabled) be allowed. The default value is Disabled. Always use Local VLAN Config Enable this option before you reboot this AP as a SM to use it to perform spectrum analysis. Once the spectrum analysis completes, disable this option before you reboot the module as an AP, Allow Frame Types Select the type of arriving frames that the AP must tag, using the VID that is stored in the Untagged Ingress VID parameter. The default value is All Frames. Dynamic Learning Specify whether the AP must (Enabled) or not (Disabled) add the VLAN IDs (VIDs) of upstream frames to the VID table. (The AP passes frames with VIDs that are stored in the table both upstream and downstream.). The default value is Enabled.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-48 VLAN Aging Timeout Specify how long the AP must keep dynamically learned VIDs. The range of values is 5 to 1440 (minutes). The default value is 25 (minutes). Note VIDs that you enter for the Management VID and VLAN Membership parameters do not time out. Management VID Enter the VID that the operator wishes to use to communicate with the module manager. The range of values is 1 to 4095. The default value is 1. QinQ EtherType Modules can be configured with 802.1ad Q-in-Q DVLAN (Double-VLAN) tagging which is a way for an operator to put an 802.1Q VLAN inside of an 802.1ad VLAN. A nested VLAN, which is the original 802.1Q tag and a new second 802.1ad tag, allows for bridging of VLAN traffic across a network and segregates the broadcast domains of 802.1Q VLANs. Q-in-Q can be used with PPPoE and/or NAT. The 802.1ad standard defines the S-VLAN as the Service Provider VLAN and the C-VLAN as the customer VLAN. The radio software does 2 layer Q-in-Q whereby the C-VLAN is the 802.1Q tag and the S-VLAN is the second layer Q tag as shown below: Table 114 Q-in-Q Ethernet frame Ethernet Header S-VLAN EthType 0x88a8 C-VLAN EthType 0x8100 IP Data EthType 0x0800 The 802.1ad S-VLAN is the outer VLAN that is configurable on the Configuration > VLAN web page of the AP. The Q-in-Q EtherType parameter is configured with a default EtherType of 0x88a8 in addition to four alternate EtherTypes that can be configured to aid in interoperability with existing networks that use a different EtherType than the default. The C-VLAN is the inner VLAN tag, which is the same as 802.1Q. As a top level concept, this operates on the outermost tag at any given time, either “pushing” a tag on or “popping” a tag off. This means packets will at most transition from an 802.1Q frame to an 801.ad frame (with a tag “pushed” on) or an untagged 802.1 frame (with the tag “popped” off. Similarly, for an 802.1ad frame, this can only transition from an 802.1ad frame to an 802.1Q frame (with the tag “popped” off) since the radio software only supports 2 levels of tags Use AP's Management VID for ICC connected SM This field allows the SM to use the AP’s management VLAN ID when the SM is registered to the AP via ICC. VLAN Not Active When VLAN is enabled in the AP, the Active Configuration block provides the following details as read-only information in this tab. In the Cambium fixed wireless broadband IP network, each device of any type is automatically a permanent member of VID 1. This facilitates deployment of devices that have VLAN enabled with those that do not.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-49 VLAN Membership Table Configuration For each VLAN in which you want the AP to be a member, enter the VLAN ID and then click the Add Member button. Similarly, for any VLAN in which you want the AP to no longer be a member, enter the VLAN ID and then click the Remove Member button. VLAN Membership table This field lists the VLANs that an AP is a member of. As the user adds a number between 1 and 4094, this number is populated here. Source VLAN (Range: 1-4094) Enter the VID for which the operator wishes to remark the 802.1p priority for the downstream packets. The range of values is 1 to 4094. The default value is 1. Remark Priority (Range 0-7) This is the priority you can assign to the VLAN Tagged packet. Priority of 0 is the highest. VLAN Remarking table As the user enters a VLAN and a Remarking priority, this information is added in this table.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-50 VLAN page of SM The VLAN tab of SM/BHS is explained in Table 115. Table 115 SM VLAN attributes Attribute Meaning VLAN Port Type By default this is Q, indicating that it is to operate in the existing manner. The other option is Q-in-Q, which indicates that it must be adding and removing the S-Tag, and adding a C-Tag if necessary for untagged packets. The VLAN Port type corresponds to the Ethernet port of the SM/BHS. Currently, the internal management interfaces will always operate as Q ports.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-51 Accept QinQ Frames This option is valid for the Q-in-Q port so that the user may force blocking of existing 802.1ad Q-in-Q frames. This way, only untagged or single tagged packets will come in and out of the Ethernet interface. If a Q-in-Q frame is about ingress or egress the Ethernet interface and this is disabled, it is dropped and a filter entry will show up on the VLAN Statistics page as DVLAN Egress or DVLAN Ingress. Allow Frame Types Select the type of arriving frames that the SM must tag, using the VID that is stored in the Untagged Ingress VID parameter. The default value is All Frames. Tagged Frames Only: The SM only tags incoming VLAN-tagged frames Untagged Frames Only: The SM will only tag incoming untagged frames Dynamic Learning Specify whether the SM must (Enable) or not (Disable) add the VIDs of upstream frames (that enter the SM through the wired Ethernet interface) to the VID table. The default value is Enable. VLAN Aging Timeout Specify how long the SM/BHS must keep dynamically learned VIDs. The range of values is 5 to 1440 (minutes). The default value is 25 (minutes). Note VIDs that you enter for the Untagged Ingress VID and Management VID parameters do not time out. Management VID Enter the VID that the SM/BHS must share with the AP/BHM. The range of values is 1 to 4095. The default value is 1. SM Management VID Pass-through Specify whether to allow the SM/BHS (Enabled) or the AP/RADIUS (Disabled) to control the VLAN settings of this SM. The default value is Enabled. When VLAN is enabled in the AP to whom this SM is registered, the Active Configuration block provides the following details as read-only information in this tab. In the Cambium fixed wireless broadband IP network, each device of any type is automatically a permanent member of VID 1. This facilitates deployment of devices that have VLAN enabled with those that do not. If disabled, MVID traffic is not allowed to or from the SM wired interface. Also, if Management VID is the same as a Port VID (Default or MAC-based), then this setting is ignored and assumed to be Enabled. Default Port VID This is the VID that is used for untagged frames and will correspond to the Q-Tag for 802.1Q frames (if VLAN Port Type is Q), or the C-Tag for 802.1ad frames (if the VLAN Port Type is Q-in- Q).
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-52 Port VID MAC Address Mapping These parameters allow operators to place specific devices onto different VLANs (802.1Q tag or 802.1ad C-tag) based on the source MAC address of the packet. If the MAC address entry is 00-00-00-00-00-00 then that entry is not used. If a packet arrives at the SM that is sourced from a device whose MAC address is in the table, then the corresponding VID is used for that frame’s Q-tag (Q port) or C-tag (Q-in-Q port). If there is no match, then the Default Port VID is used. This table is also used in the downstream direction for removal of the tag based on the destination MAC address so that an untagged (for Q port) or Q-Tagged (for Q-in-Q port) frame is delivered to the end device. You may use wildcards for the non-OUI (Organizationally Unique Identifier) portion of the MAC address, which is the last 3 bytes. MAC addresses contain 6 bytes, the first 3 of which are the OUI of the vendor that manufactured the device and the last 3 are unique to that vendor OUI. If you want to cover all devices from a known vendor’s OUI, you have to specify 0xFF for the remaining 3 bytes. So, for example, if you wanted all devices from a specific vendor with an OUI of 00-95-5b (which is a Netgear OUI) to be on the same VID of 800, you have to specify an entry with MAC address 00-95-5b-ff-ff-ff. Then, any device underneath of the SM with MAC addresses starting with 00-95-5b is put on VLAN 800. Provider VID The provider VID is used for the S-tag. It is only used if the Port Type is Q-in-Q and will always be used for the S-tag. If an existing 802.1Q frame arrives, the Provider VID is what is used for adding and removing of the outer S-tag. If an untagged frame arrives to a Q-in-Q port, then the Provider VID is the S-tag and the Default Port VID (or Port VID MAC Address Mapping, if valid) is used for the C-tag. Active Configuration, Default Port VID This is the value of the parameter of the same name, configured above. Active Configuration, MAC Address VID Map This is the listing of the MAC address VIDs configured in Port VID MAC Address Mapping. Active Configuration, Management VID This is the value of the parameter of the same name, configured above. Active Configuration, SM Management VID Pass-Through This is the value of the parameter of the same name, configured above. Active Configuration, Dynamic Aging Timeout This is the value of the VLAN Aging Timeout parameter configured above. Active Configuration, Allow Learning Yes is displayed if the value of the Dynamic Learning parameter above is Enabled. No is displayed if the value of Dynamic Learning is Disabled. Active Configuration, Allow Frame Type This displays the selection that was made from the drop-down list at the Allow Frame Types parameter above.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-53 Active Configuration, QinQ This is set to Enabled if VLAN Port Type is set to QinQ, and is set to Disabled if VLAN Port Type is set to Q. Active Configuration, QinQ EthType This is the value of the QinQ EtherType configured in the AP. Active Configuration, Allow QinQ Tagged Frames This is the value of Accept QinQ Frames, configured above. Active Configuration, Current VID Member Set, VID Number This column lists the ID numbers of the VLANs in which this module is a member, whether through assignment or through dynamic learning. Active Configuration, Current VID Member Set, Type For each VID number in the first column, the entry in this column correlates the way in which the module became and continues to be a member: Permanent—This indicates that the module was assigned the VID number through direct configuration by the operator. Dynamic—This indicates that the module adopted the VID number through enabled dynamic learning, when a tagged packet from a SM behind it in the network or from a customer equipment that is behind the SM in this case, was read. Active Configuration, Current VID Member Set, Age For each VID number in the first column of the table, the entry in this column reflects whether or when the VID number will time out: Permanent type - Number never times out and this is indicated by the digit 0. Dynamic type - Age reflects what is configured in the VLAN Aging Timeout parameter in the Configuration => VLAN tab of the AP or reflects a fewer number of minutes that represents the difference between what was configured and what has elapsed since the VID was learned. Each minute, the Age decreases by one until, at zero, the AP deletes the learned VID, but can it again from packets sent by elements that are beneath it in the network. Note Values in this Active Configuration block can differ from attempted values in configurations: The AP can override the value that the SM has configured for SM Management VID Pass-Through.

Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-58 PPPoE page of SM Applicable products PMP : SM Point-to-Point Protocol over Ethernet (PPPoE) is a protocol that encapsulates PPP frames inside Ethernet frames (at Ethernet speeds). Benefits to the network operator may include  Access control  Service monitoring  Generation of statistics about activities of the customer  Re-use of infrastructure and operational practices by operators who already use PPP for other networks PPPoE options are configurable for the SM only, and the AP indicates whether or not PPPoE is enabled for a specific subscriber. When PPPoE is enabled, once the RF session comes up between the SM and the AP, the SM will immediately attempt to connect to the PPPoE Server. You can monitor the status of this by viewing the PPPoE Session Log in the Logs section (Administrator only). Every time the RF session comes up, the SM will check the status of the link and if it is down, the SM will attempt to redial the link if necessary depending on the Timer Type. Also, on the Configuration page, the user may ‘Connect’ or ‘Disconnect’ the session manually. This can be used to override the session to force a manual disconnect and/or reconnect if there is a problem with the session. In order to enable PPPoE, NAT MUST be enabled on the SM and Translation Bridging MUST be disabled on the AP. These items is strictly enforced for you when you are trying to enable PPPoE. A message will indicate any prerequisites not being met. Also, the NAT Public IP DHCP client cannot be enabled, because the NAT Public IP is received through the IPCP process of the PPPoE discovery stages. The pre-requisites are:  NAT MUST be enabled on the SM o NAT DHCP Client is disabled automatically. The NAT public IP is received from the PPPoE Server. o NAT Public Network Interface Configuration will not be used and must be left to defaults. Also NAT Public IP DHCP is disabled if it is enabled.  Translation Bridging MUST be DISABLED on the AP o This will only be determined if the SM is in session since the SM won’t know the AP configuration otherwise. If the SM is not in session, PPPoE can be enabled but if the SM goes into session to a Translation Bridge-enabled AP, then PPPoE will not be enabled. The PPPoE configuration parameters are explained in Table 119.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-59 Table 119 SM PPPoE attributes Attribute Meaning Access Concentrator An optional entry to set a specific access concentrator to connect to for the PPPoE session. If this is blank, the SM will accept the first access concentrator which matches the service name (if specified). This is limited to 32 characters. Service Name An optional entry to set a specific service name to connect to for the PPPoE session. If this is left blank the SM will accept the first service option that comes back from the access concentrator specified above, if any. This is limited to 32 characters. Authentication Type None means that no PPPoE authentication is implemented CHAP/PAP means that CHAP authentication is attempted first, then PAP authentication. The same password is used for both types. User Name This is the CHAP/PAP user name that is used if CHAP/PAP authentication is selected. If None is selected for authentication then this field is unused. This is limited to 32 characters. Password This is the CHAP/PAP password that is used if PAP authentication is selected. If None is selected for authentication then this field is unused. This is limited to 32 characters. MTU Use MTU Received from PPPoE Server causes the SM to use the MRU of the PPPoE server received in LCP as the MTU for the PPPoE link.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-60 Use User Defined MTU allows the operator to specify an MTU value to use to override any MTU that may be determined in the LCP phase of PPPoE session setup. If this is selected, the user is able to enter an MTU value up to 1492. However, if the MTU determined in LCP negotiations is less than this user-specified value, the SM will use the smaller value as its MTU for the PPPoE link. Timer Type Keep Alive is the default timer type. This timer will enable a keepalive that will check the status of the link periodically. The user can set a keepalive period. If no data is seen from the PPPoE server for that period, the link is taken down and a reconnection attempt is started. For marginal links, the keep alive timer can be useful so that the session will stay alive over periodic dropouts. The keepalive timer must be set such that the session can outlast any session drop. Some PPPoE servers will have a session check timer of their own so that the timeouts of the server and the SM are in sync, to ensure one side does not drop the session prematurely. Idle Timeout enables an idle timer that checks the usage of the link from the customer side. If there is no data seen from the customer for the idle timeout period, the PPPoE session is dropped. Once data starts flowing from the customer again, the session is started up again. This timer is useful for users who may not be using the connection frequently. If the session is idle for long periods of time, this timer will allow the resources used by the session to be returned to the server. Once the connection is used again by the customer, the link is reestablished automatically. Timer Period The length in seconds of the PPPoE keepalive timer. TCP MSS Clamping If this is enabled, then the SM will alter TCP SYN and SYN-ACK packets by changing the Maximum Segment Size to be compatible with the current MTU of the PPPoE link. This way, the user does not have to worry about MTU on the client side for TCP packets. The MSS is set to the current MTU – 40 (20 bytes for IP headers and 20 bytes for TCP headers). This will cause the application on the client side to not send any TCP packets larger than the MTU. If the network is exhibiting large packet loss, try enabling this option. This may not be an option on the PPPoE server itself. The SM will NOT reassemble IP fragments, so if the MTUs are incorrect on the end stations, then MSS clamping will solve the problem for TCP connections.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-61 IP4 and IPv6 Applicable products PMP : AP SM PTP: BHM  BMS IPv4 and IPv6 Prioritization 450 Platform Family provides operators the ability to prioritize IPv6 traffic in addition to IPv4 traffic. IPv6/IPv4 prioritization can be configured by selecting a CodePoint and the corresponding priority from the GUI of the AP/BHM and the IPv6/IPv4 packet is set up accordingly. There is no GUI option for selecting IPv6 or IPv4 priority. Once the priority is set, it is set for IPv4 and IPv6 packets. Configuring IPv4 and IPv6 Priority IPv4 and IPv6 prioritization is set using the DiffServ tab on the AP/BHM and SM/BHS (located at Configuration > DiffServ). A priority set to a specific CodePoint will apply to both IPv4 and IPv6 traffic. Table 120 DiffServ attributes – AP/BHM Attribute Meaning CodePoint 1 through CodePoint 47 CodePoint 49 through CodePoint 55 CodePoint 57 through CodePoint 63 Priorities of 0 through 3 map to the low-priority channel; 4 through 7 to the high- priority channel. The mappings are the same as 802.1p VLAN priorities. Consistent with RFC 2474 CodePoint 0 is predefined to a fixed priority value of 0 (low-priority channel). CodePoint 48 is predefined to a fixed priority value of 6 (high-priority channel). CodePoint 56 is predefined to a fixed priority value of 7 (high-priority channel). Operator cannot change any of these three fixed priority values. Among the settable parameters, the priority values (and therefore the handling of packets in the high or low priority channel) are set in the AP/BHM for all downlinks within the sector and in the SM/BHS for each uplink.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-62 CodePoint Select This represents the CodePoint Selection to be modified via Priority Select Priority Select The priority setting input for the CodePoint selected in CodePoint Select Priority Precedence Allows operator to decide if 802.1p or DiffServ priority bits must be used first when making priority decisions. PPPoE Control Message Priority Operators may configure the AP/BHM to utilize the high priority channel for PPPoE control messages. Configuring the AP/BHM in this fashion can benefit the continuity of PPPoE connections when there are issues with PPPoE sessions being dropped in the network. This prioritization may be configured in the DiffServ tab in the Configuration menu of the AP/BHM. IPv4 and IPv6 Filtering The operator can filter (block) specified IPv6 protocols including IPv4 and ports from leaving the AP/BHM and SM/BHS and entering the network. This protects the network from both intended and inadvertent packet loading or probing by network users. By keeping the specified protocols or ports off the network, this feature also provides a level of protection to users from each other. Configuring IPv4 and IPv6 Filtering IPv6 filters are set using the Protocol Filtering tab on the AP/BHM and SM/BHS (at Configuration > Protocol Filtering). Once a filter is set for a packet type, those packets will not be sent over the RF interface depending on “Filter Direction” setting.
Chapter 7: Configuration Configuring IP and Ethernet interfaces Page 7-63 Table 121 Packet Filter Configuration attributes Attribute Meaning Packet Filter Types For any box selected, the Protocol and Port Filtering feature blocks the associated protocol type. To filter packets in any of the user-defined ports, you must do all of the following:  Check the box for User Defined Port n (See Below) in the Packet Filter Types section of this tab.  Provide a port number at Port #n. in the User Defined Port Filtering Configuration section of this tab

Chapter 7: Configuration Upgrading the software version and using CNUT Page 7-65 Upgrading the software version and using CNUT This section consists of the following procedures:  Checking the installed software version on page 7-64  Upgrading to a new software version on page 7-64 Caution If the link is operational, ensure that the remote end of the link is upgraded first using the wireless connection, and then the local end can be upgraded. Otherwise, the remote end may not be accessible. Use CNUT 4.10.4 or later version and always refer to the software release notes before upgrading system software. The release notes are available at: https://support.cambiumnetworks.com/files/pmp450 https://support.cambiumnetworks.com/files/ptp450 Checking the installed software version To check the installed software version, follow these instructions: Procedure 18 Checking the installed software version 1 Click on General tab under Home menu. 2 Note the installed Software Version (under Device Information): PMP/PTP 450/450i/450m 3 Go to the support website (see Contacting Cambium Networks on page 1) and find Point-to-Multipoint software updates. Check that the latest 450 Platform Family software version is the same as the installed Software Version. 4 To upgrade software to the latest version, see Upgrading to a new software version on page 7-64. Upgrading to a new software version All 450 platform modules are upgraded using the Canopy Network Updater Tool. The Canopy Network Updater Tool (CNUT) manages and automates the software upgrade process for a Canopy radio, or CMM4 (but not its 14-port switch) across the network. This eliminates the need for an administrator to visit each radio in the network (or each AP/BHM while using the Autoupdate feature) to upgrade the modules.
Chapter 7: Configuration Upgrading the software version and using CNUT Page 7-66 Note Please ensure that you have the most up-to-date version of CNUT by browsing to the Customer Support Web Page located: http://www.cambiumnetworks.com/support/management-tools/cnut This section includes an example of updating a single unit before deployment. System-wide upgrading procedures may be found in the CNUT Online Help manual, which can be found on the Cambium support website (see Contacting Cambium Networks on page 1). CNUT functions The Canopy Network Updater tool has the following functions:  Automatically discovers all network elements  Executes a UDP command that initiates and terminates the Auto-update mode within APs/BHMs. This command is both secure and convenient: o For security, the AP/BHM accepts this command from only the IP address that you specify in the Configuration page of the AP/BHM. o For convenience, Network Updater automatically sets this Configuration parameter in the APs/BHMs to the IP address of the Network Updater server when the server performs any of the update commands.  CNUT supports HTTP and HTTPS  Allows you to choose the following among updating: o Your entire network. o Only elements that you select. o Only network branches that you select.  Provides a Script Engine that you can use with any script that: o You define. o Cambium supplies.  Configurability of any of the following to be the file server for image files: o The AP/BHM, for traditional file serving via UDP commands and monitoring via UDP messaging o CNUT HTTP/HTTPS Server, for upgrading via SNMP commands and monitoring via SNMP messaging. This also supports an option to either set the image order specifically for this file server or to allow the AP to determine the order. o Local TFTP Server, for traditional file serving via UDP commands and monitoring via UDP messaging. This supports setting the number of simultaneous image transfers per AP/BHM  The capability to launch a test of connectivity and operational status of the local HTTP, HTTPS and TFTP file servers  An interface that supports efficient specification of the proper IP address for the local file server(s) where Network Updater resides on a multi-homed computer  An md5 checksum calculator utility for identifying corruption of downloaded image files before Network Updater is set to apply them. Network element groups With the Canopy Network Updater Tool, you can identify element groups composed of network elements that you select. Identifying these element groups does the following:
Chapter 7: Configuration Upgrading the software version and using CNUT Page 7-67  Organizes the display of elements (for example, by region or by AP/BHM cluster).  Allows to: o Perform an operation on all elements in the group simultaneously. o Set group-level defaults for ftp password access and SNMP Community String (defaults that can be overridden in an individual element when necessary). Network layers A typical network contains multiple layers of elements, with each layer farther from the Point of Presence. For example, SMs (or BHS) are behind an AP/BHM and thus, in this context, at a lower layer than the AP/BHM. Correctly portraying these layers in Network Updater is essential so that Network Updater can perform radio and AP/BHM cluster upgrades in an appropriate order. Script engine Script Engine is the capability in Network Updater that executes any user-defined script against any network element or element group. This capability is useful for network management, especially for scripts that you repetitively execute across your network. The Autodiscovery capability in Network Updater finds all of your network elements. This comprehensive discovery:  Ensures that, when you intend to execute a script against all elements, the script is indeed executed against all elements.  Maintains master lists of elements (element groups) against which you selectively execute scripts. The following scripts are included with CNUT:  Gather Customer Support Information  Set Access Point Authentication Mode  Set Autoupdate Address on APs/BHMs  Set SNMP Accessibility  Reset Unit
Chapter 7: Configuration Upgrading the software version and using CNUT Page 7-68 Software dependencies for CNUT CNUT functionality requires  one of the following operating systems o Windows® 2000 o Windows Server 2003 o Windows 7 and Windows 8 o Windows XP or XP Professional o Red Hat Enterprise Linux (32-bit) Version 4 or 5  Java™ Runtime Version 2.0 or later (installed by the CNUT installation tool) CNUT download CNUT can be downloaded together with each system release that supports CNUT. Software for these system releases is available from http://www.cambiumnetworks.com/support/management-tools/cnut/, as either:  A .zip file for use without the CNUT application.  A .pkg file that the CNUT application can open. Upgrading a module prior to deployment To upgrade to a new software version, follow this: Procedure 19 Upgrading a module prior to deployment 1 Go to the support website (see Contacting Cambium Networks on page 1) and find Point-to-Multipoint software updates. Download and save the required software image. 2 Start CNUT 3 If you don’t start up with a blank new network file in CNUT, then open a new network file with the New Network Archive operation (located at File > New Network). 4 Enter a new network element to the empty network tree5-9 using the Add Elements to Network Root operation (located at Edit > Add Elements to Network Root). 5 In the Add Elements dialogue, select a type of Access Point or Subscriber Module and enter the IP address of 169.254.1.1. 6 Make sure that the proper Installation Package is active with the Package Manager dialogue (located at Update > Manage Packages). 7 To verify connectivity with the radio, perform a Refresh, Discover Entire Network operation (located at View > Refresh/Discover Entire Network). You must see the details columns for the new element filled in with ESN and software version information. 8 Initiate the upgrade of the radio using Update Entire Network Root operation (located at Update > Update Entire Network Root). When this operation finishes, the radio is done being upgraded.
Chapter 7: Configuration General configuration Page 7-69 General configuration The Configuration > General page of the AP/BMH or BHM/BHS contains many of the configurable parameters that define how the ratio’s operate in sector or backhaul.

Table 122 General page attributes – PMP 450i AP
Chapter 7: Configuration General configuration Page 7-70 Attribute Meaning Ethernet Port Selection Ethernet Port selection is applicable to the 450m platform only with two choices in the drop-down list:  Main: A selection of main indicates that link connectivity and power to the 450m is provided through the RF45 connection on the Main port of the AP  SFP: A selection of SFP indicates that link connectivity will be provided through the SFP port on the 450m Power continues to be provided via the RJ45 Main port Link Speeds From the drop-down list of options, select the type of link speed for the Ethernet connection. The Auto settings allow the two ends of the link to automatically negotiate with each other the best possible speed, and check whether the Ethernet traffic is full duplex or half duplex. However, some Ethernet links work best when either:  both ends are set to the same forced selection  both ends are set to auto-negotiate and both have capability in least one common speed and traffic type combination. 802.3at Type 2 PoE Status and PoE Classification (PMP 450i Series only) When the PoE Classification functionality is enabled and if Type 2 power is not present, the PAs do not power up and draw too much power. By default, the PoE Classification feature is disabled and the PAs will power up regardless of the classification presented by the power source. This is supported only on 450i series devices. PoE Classification configuration status also can be check under home > General > Device Information tab: Configuration Source See Setting the Configuration Source on page 7-203. Sync Input See Configuring synchronization on page 7-97
Chapter 7: Configuration General configuration Page 7-71 Device Type Standard: The Autosync mechanism will source GPS synchronization from the AP’s RJ-11 port, the AP’s power port, or from the device on-board GPS module. Remote: The Autosync mechanism will source GPS synchronization from the AP’s RJ-11 port or from the device on-board GPS module. Region From the drop-down list, select the region in which the radio is operating. Country From the drop-down list, select the country in which the radio is operating. Unlike selections in other parameters, your Country selection requires a Save Changes and a Reboot cycle before it will force the context-sensitive GUI to display related options (for example, Alternate Frequency Carrier 1 and 2 in the Configuration > Radio tab). PMP 450i Series ODUs shipped to the United States is locked to a Region Code setting of “United States”. Units shipped to regions other than the United States must be configured with the corresponding Region Code to comply with local regulatory requirements. Country Code settings affect the radios in the following ways:  Maximum transmit power limiting (based on radio transmitter power plus configured antenna gain)  DFS operation is enabled based on the configured region code, if applicable For more information on how transmit power limiting and DFS is implemented for each country, see the PMP 450 Planning Guide. Webpage Auto Update Enter the frequency (in seconds) for the web browser to automatically refresh the web-based interface. The default setting is 0. The 0 setting causes the web-based interface to never be automatically refreshed. Bridge Entry Timeout Specify the appropriate bridge timeout for correct network operation with the existing network infrastructure. The Bridge Entry Timeout must be a longer period than the ARP (Address Resolution Protocol) cache timeout of the router that feeds the network. Caution An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. Translation Bridging Optionally, you can configure the AP to change the source MAC address in every packet it receives from its SMs to the MAC address of the SM that bridged the packet, before forwarding the packet toward the public network. If you do, then: Not more than 128 IP devices at any time are valid to send data to the AP from behind the SM. SM populates the Translation Table tab of its Statistics web page, displaying the MAC address and IP address of all the valid connected devices.
Chapter 7: Configuration General configuration Page 7-72 Each entry in the Translation Table is associated with the number of minutes that have elapsed since the last packet transfer between the connected device and the SM. If 128 are connected and another attempts to connect: If no Translation Table entry is older than 255 minutes, the attempt is ignored. If an entry is older than 255 minutes, the oldest entry is removed and the attempt is successful. the Send Untranslated ARP parameter in the General tab of the Configuration page can be: Disabled, so that the AP overwrites the MAC address in Address Resolution Protocol (ARP) packets before forwarding them. Enabled, so that the AP forwards ARP packets regardless of whether it has overwritten the MAC address. When this feature is disabled, the setting of the Send Untranslated ARP parameter has no effect, because all packets are forwarded untranslated (with the source MAC address intact). Send Untranslated ARP If the Translation Bridging parameter is set to Enabled, then the Send Untranslated ARP parameter can be: Disabled - so that the AP will overwrite the MAC address in Address Resolution Protocol (ARP) packets before forwarding them. Enabled - so that the AP will forward ARP packets regardless of whether it has overwritten the MAC address. If the Translation Bridging parameter is set to Disabled, then the Send Untranslated ARP parameter has no effect. SM Isolation Prevent or allow SM-to-SM communication by selecting from the following drop-down menu items: Disable SM Isolation (the default selection). This allows full communication between SMs. Block SM Packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication. Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise are handled SM to SM, through the Ethernet port of the AP. Forward Unknown Unicast Packets Enabled: All unknown Unicast packets (no entry in the AP’s bridge table) received via the AP’s Ethernet LAN interface are forwarded to registered SMs. If the target device is situated beneath a particular SM, when the device responds the SM and AP will learn and add the device to their bridge tables so that subsequent packets to that device is bridged to the proper SM. Disabled: All unknown Unicast packets (no entry in the AP’s bridge table) received via the AP’s Ethernet LAN interface are discarded at the AP. Update Application Address Enter the address of the server to access for software updates on this AP and registered SMs.
Chapter 7: Configuration General configuration Page 7-73 Prioritize TCP ACK To reduce the likelihood of TCP acknowledgement packets being dropped, set this parameter to Enabled. This can improve throughput that the end user perceives during transient periods of congestion on the link that is carrying acknowledgements. This parameter, when enabled, can be particularly useful when running bi-direction FTP sessions over the link. If a link is primarily used for video surveillance, it is recommended to set this parameter to Disable. Multicast Destination Address Using Link Layer Discovery Protocol (LLDP), a module exchanges multicast addresses with the device to which it is wired on the Ethernet interface. Although some switches (CMM4, for example) do not pass LLDP addresses upward in the network, a radio can pass it as the value of the Multicast Destination Address parameter value in the connected device that has it populated. DHCP Relay Agent The AP may act as a DHCP relay for SMs and CPEs underneath it. The AP will make use of the DHCP Option 82 (DHCP Relay Agent Information) from RFC 3046 when performing relay functions. The AP offers two types of DHCP relay functionality: Full Relay Information. Configuring the DHCP Full Relay Operation will take broadcast DHCP packets and send them to a Unicast server in unicast mode. This way the DHCP requests and replies can be routed like any other UDP packet. Only Insert Option 82. This option leaves the DHCP request on its broadcast domain as opposed to DHCP Full Relay Operation which will turn it into a unicast packet. In order to accommodate setting up pools or classes for different VLANs, the Option 82 field will include information to tell the server what VLAN the client is on. DHCP Server (Name or IP Address) The DHCP relay server may be either a DNS name or a static IP address in dotted decimal notation. Additionally the management DNS domain name may be toggled such that the name of the DHCP relay server only needs to be specified and the DNS domain name is automatically appended to that name. The default DHCP relay server addresses is 255.255.255.255 with the appending of the DNS domain name disabled. Latitude Longitude Height Physical radio location data may be configured via the Latitude, Longitude and Height fields. Latitude and Longitude is measured in Decimal Degree while the Height is calculated in Meters.

Chapter 7: Configuration General configuration Page 7-77 Ethernet Link Enable/Disable Specify whether to enable or disable Ethernet/802.3 connectivity on the wired port of the SM. This parameter has no effect on the wireless link. When you select Enable, this feature allows traffic on the Ethernet/802.3 port. This is the factory default state of the port. When you select Disable, this feature prevents traffic on the port. Typical cases of when you may want to select Disable include: The subscriber is delinquent with payment(s). You suspect that the subscriber is sending or flooding undesired broadcast packets into the network, such as when  a virus is present in the subscriber’s computing device.  the subscriber’s home router is improperly configured. Region This parameter allows you to set the region in which the radio will operate. The SM radio automatically inherits the Region type of the master. This behavior ignores the value of the Region parameter in the SM, even when the value is None. Nevertheless, since future system software releases may read the value in order to configure some other region-sensitive feature(s), this parameter must be always set to the value that corresponds to the local region. Country This parameter allows you to set the country in which the radio will operate. The SM radio automatically inherits the Country Code type of the master. This behavior ignores the value of the Country parameter in the SM, even when the value is None. Nevertheless, since future system software releases may read the value in order to configure some other region-sensitive feature(s), this parameter must be always set to the value that corresponds to the local region. PMP/PTP 450i Series ODU shipped to the United States is locked to a Region Code setting of “United States”. Units shipped to regions other than the United States must be configured with the corresponding Region Code to comply with local regulatory requirements. Webpage Auto Update See Table 122 General page attributes – PMP 450i AP on page 7-68 Show Idle Sessions This parameter allows to enable or disable displaying idle sessions. Bridge Entry Timeout Specify the appropriate bridge timeout for correct network operation with the existing network infrastructure. Timeout occurs when the AP encounters no activity with the SM (whose MAC address is the bridge entry) within the interval that this parameter specifies. The Bridge Entry Timeout must be a longer period than the ARP (Address Resolution Protocol) cache timeout of the router that feeds the network.
Chapter 7: Configuration General configuration Page 7-78 Caution This parameter governs the timeout interval, even if a router in the system has a longer timeout interval. The default value of this field is 25 (minutes). An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. Bridge Table Size This parameter allows to restrict devices to connect to the SM. It is configurable from 4 to 4096. Note Configure Bridge Table Restriction parameter to Drop packets if MAC address is not in bridge table option to restrict the number of devices configured from connecting to SM. Bridge Table Restriction This parameter allows to either allow or restrict devices to connect to SM using the following options:  Drop packets if MAC address is not in bridge table: Select this option to restrict communication from devices not listed in bridge table.  Forward packets even if MAC address is not in bridge table: Select this option to allow communication from any device. Frame Timing Pulse Gated If this SM extends the sync pulse to a BH master or an AP, select either Enable—If this SM loses sync from the AP, then do not propagate a sync pulse to the BH timing master or other AP. This setting prevents interference in the event that the SM loses sync. Disable—If this SM loses sync from the AP, then propagate the sync pulse to the BH timing master or other AP. Multicast Destination Address Using Link Layer Discovery Protocol (LLDP), a module exchanges multicast addresses with the device to which it is wired on the Ethernet interface.

Chapter 7: Configuration Setting up time and date Page 7-96 Setting up time and date Time page of 450 Platform Family - AP/BHM Applicable products PMP : AP PTP:BHM The Time page of 450 Platform Family AP/BHM is explained in Table 130. Table 130 450 Platform Family - AP/BHM Time attributes Attribute Meaning NTP Server (Name or IP Address) The management DNS domain name may be toggled such that the name of the NTP server only needs to be specified and the DNS domain name is automatically appended to that name. NTP Server 1 (Name or IP Address) NTP Server 2 (Name or IP Address) NTP Server 3 (Name or IP Address) To have each log in the AP/BHM correlated to a meaningful time and date, either a reliable network element must pass time and date to the AP/BHM or must set the time and date whenever a power cycle of the AP/BHM has occurred. A network element passes time and date in any of the following scenarios:  A connected CMM4 passes time and date (GPS time and date, if received).  A connected CMM4 passes the time and date (GPS time and date, if received), but only if both the CMMr is operating on CMMr Release 2.1 or later release. (These releases include NTP server functionality.)
Chapter 7: Configuration Setting up time and date Page 7-97  A separate NTP server (including APs/BHMs receiving NTP data) is addressable from the AP/BHM. If the AP/BHM needs to obtain time and date from a CMM4, or a separate NTP server, enter the IP address or DNS name of the CMM4 or NTP server on this tab. To force the AP/BHM to obtain time and date before the first (or next) 15-minute interval query of the NTP server, click Get Time via NTP. The polling of the NTP servers is done in a sequential fashion, and the polling status of each server is displayed in the NTP Update Log section of the Time Configuration page. An entry of 0.0.0.0 in any of the NTP Server fields indicates an unused server configuration. NTP Server(s) in Use Lists the IP addresses of servers used for NTP retrieval. Time Zone The Time Zone option may be used to offset the received NTP time to match the operator’s local time zone. When set on the AP/BHM, the offset is set for the entire sector SMs (or BHS) are notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the SMs(or BHS) is notified of the change in a best effort fashion, meaning some SMs//BHSs may not pick up the change until the next re-registration. Time Zone changes are noted in the Event Log of the AP/BHM and SM/BHS. System Time The current time used by the system. Last NTP Time Update The last time that the system time was set via NTP. Time This field may be used to manually set the system time of the radio. Date This field may be used to manually set the system date of the radio. NTP Update Log This field shows NTP clock update log. It includes NTP clock update Date and Time stamp along with server name.
Chapter 7: Configuration Configuring synchronization Page 7-98 Configuring synchronization Applicable products PMP : AP PTP: BHM This section describe synchronization options for PMP and PTP configuration. This Sync Input parameter can be configured under Sync Setting tab of Configure > General page (see General configuration on page 7-68). PMP/PTP 450i Series has following synchronization options:  AutoSync  AutoSync + Free Run  Generate Sync  Free Run Before GPS Sync Figure 137 Sync Setting configuration AutoSync For PTP, the BHM automatically receives sync from one of the following sources:  GPS Sync over Timing Port (UGPS, co-located AP GPS sync output, or “Remote ” Device feed from a registered SM’s GPS sync output)  GPS Sync over Power Port (CMM4) Upon AP/BM power on, the AP/BHM does not transmit until a valid synchronization pulse is received from one of the sources above. If there is a loss of GPS synchronization pulse, within two seconds the AP/BHM automatically attempts to source GPS signaling from another source. In case of PMP, when there are synchronization sources on both the timing port and the power port, the power port GPS source is chosen first. If no valid GPS signal is received, the AP/BHM ceases transmission and SM/BHS registration is lost until a valid GPS signal is received again on the AP or BHM. Note After an AP reboot, the sync acquisition takes a little longer than it had on 450i (anywhere from 40 seconds to 120 seconds difference).
Chapter 7: Configuration Configuring synchronization Page 7-99 AutoSync + Free Run This mode operates similarly to mode “AutoSync”, but if a previously received synchronization signal is lost and no GPS signaling alternative is achieved, the AP/BHM automatically changes to synchronization mode “Generate Sync”. While SM registration ins maintained, in this mode there is no synchronization of APs/BHMs that can “hear” each other; the AP/BHM will only generate a sync signal for the local AP/BHM and its associated SMs/BHS. Once a valid GPS signal is obtained again, the AP/BHM automatically switches to receiving synchronization via the GPS source and SM/BHS registration is maintained. When the Sync Input field is set to Autosync or Autosync + Free Run, other options become available to be set e.g. UGPS Power and other fields. This is true on APs and BHMs. Note In mode AutoSync + Free Run, if a GPS signal is never achieved initially, the system will not switch to “Free Run” mode, and SMs/BHS will not register to the AP/BHM. A valid GPS signal must be present initially for the AP to switch into “Free Run” mode (and to begin self-generating a synchronization pulse). Also, When an AP/BHM is operating in “Free Run” mode, over a short time it will no longer be synchronized with co-located or nearby APs/BHMs (within radio range). Due to this lack of transmit and receive synchronization across APs/BHMs or across systems, performance while in “Free Run” mode may be degraded until the APs/BHMs operating in “Free Run” mode regain a external GPS synchronization source. Careful attention is required to ensure that all systems are properly receiving an external GPS synchronization pulse, and please consider “Free Run” mode as an emergency option. Generate Sync (factory default) This option may be used when the AP/BHM is not receiving GPS synchronization pulses from either a CMM4 or UGPS module, and there are no other APs/BHMs active within the link range. Using this option will not synchronize transmission of APs/BHMs that can “hear” each other; it will only generate a sync signal for the local AP/BHM and its associated SMs/BHS. Note When an AP/BHM has its "Regional Code" set to "None", The radio will not provide valid Sync Pulse Information. There is a RED warning that the radio will not transmit, but the user might expect to see a valid sync if the radio is connected to a working CMM4 or UGPS.

Chapter 7: Configuration Configuring security Page 7-105 Requiring SM Authentication Applicable products PMP : AP SM Through the use of a shared AP key, or an external RADIUS (Remote Authentication Dial In User Service) server, it enhances network security by requiring SMs to authenticate when they register. For descriptions of each of the configurable security parameters on the AP, see Configuring Security on page 7-114. For descriptions of each of the configurable security parameters on the SM, see Security on page 7-119. Operators may use the AP’s Authentication Mode field to select from among the following authentication modes:  Disabled—the AP requires no SMs to authenticate (factory default setting).  Authentication Server —the AP requires any SM that attempts registration to be authenticated in Wireless Manager before registration  AP PreShared Key - The AP acts as the authentication server to its SMs and will make use of a user-configurable pre-shared authentication key. The operator enters this key on both the AP and all SMs desired to register to that AP. There is also an option of leaving the AP and SMs at their default setting of using the “Default Key”. Due to the nature of the authentication operation, if you want to set a specific authentication key, then you MUST configure the key on all of the SMs and reboot them BEFORE enabling the key and option on the AP. Otherwise, if you configure the AP first, none of the SMs is able to register.  RADIUS AAA - When RADIUS AAA is selected, up to 3 Authentication Server (RADIUS Server) IP addresses and Shared Secrets can be configured. The IP address(s) configured here must match the IP address(s) of the RADIUS server(s). The shared secret(s) configured here must match the shared secret(s) configured in the RADIUS server(s). Servers 2 and 3 are meant for backup and reliability, not for splitting the database. If Server 1 doesn’t respond, Server 2 is tried, and then server 3. If Server 1 rejects authentication, the SM is denied entry to the network, and does not progress trying the other servers. For more information on configuring the PMP 450 Platform network to utilize a RADIUS server, see Configuring a RADIUS server on page 7-226.
Chapter 7: Configuration Configuring security Page 7-106 Filtering protocols and ports Applicable products PMP : AP SM PTP: BHM  BMS The filtering protocols and ports allows to configure filters for specified protocols and ports from leaving the AP/SM/BHM/BHS and entering the network. See Filtering protocols and ports on page 3-45. Protocol filtering page of 450 Platform Family AP/BHM The Protocol Filtering page of 450 Platform Family - AP/BHM is explained in Table 135. Table 135 AP/BHM Protocol Filtering attributes
Chapter 7: Configuration Configuring security Page 7-107 Attribute Meaning Packet Filter Types For any box selected, the Protocol and Port Filtering feature blocks the associated protocol type. To filter packets in any of the user-defined ports, must do all of the following: Check the box for User Defined Port n (See Below) in the Packet Filter Types section of this tab. In the User Defined Port Filtering Configuration section of this tab:  provide a port number at Port #n.  enable TCP and/or UDP by clicking the associated radio button Filter Direction Operators may choose to filter upstream (uplink) RF packets or downstream (downlink) RF packets. User Defined Port Filtering Configuration You can specify ports for which to block subscriber access, regardless of whether NAT is enabled. RF Telnet Access RF Telnet Access restricts Telnet access to the AP/BHM from a device situated below a network SM/BHS (downstream from the AP/BHM). This is a security enhancement to restrict RF-interface sourced AP access specifically to the LAN1 IP address and LAN2 IP address (Radio Private Address, typically 192.168.101.[LUID]). This restriction disallows unauthorized users from running Telnet commands on the AP/BHM that can change AP/BHM configuration or modifying network-critical components such as routing and ARP tables. PPPoE PADI Downlink Forwarding Enabled: the AP/BHM allows downstream and upstream transmission of PPPoE PADI packets. By default, PPPoE PADI Downlink Forwarding is set to “Enabled”. Disabled: the AP/BHM disallows PPPoE PADI packets from entering the Ethernet interface and exiting the RF interface (downstream to the SM/BHS). PPPoE PADI packets are still allowed to enter the AP’s RF interface and exit the AP’s /BHM’s Ethernet interface (upstream).

Chapter 7: Configuration Configuring security Page 7-110 Filtering management through Ethernet See Filtering management through Ethernet on page 3-49. Allowing management only from specified IP addresses See Allowing management from only specified IP addresses on page 3-50. Restricting radio Telnet access over the RF interface RF Telnet Access restricts Telnet access to the AP from a device situated below a network SM (downstream from the AP). This is a security enhancement to restrict RF-interface sourced AP access specifically to the LAN1 IP address and LAN2 IP address (Radio Private Address, typically 192.168.101. [LUID]). This restriction disallows unauthorized users from running Telnet commands on the AP that can change AP configuration or modifying network-critical components such as routing and ARP tables. The RF Telnet Access may be configured via the AP GUI or via SNMP commands, and RF Telnet Access is set to “Enabled” by default. Once RF Telnet Access is set to “Disabled”, if there is a Telnet session attempt to the AP originating from a device situated below the SM (or any downstream device), the attempt is dropped. This also includes Telnet session attempts originated from the SM’s management interface (if a user has initiated a Telnet session to a SM and attempts to Telnet from the SM to the AP). In addition, if there are any active Telnet connections to the AP originating from a device situated below the SM (or any downstream device), the connection is dropped. This behavior must be considered if system administrators use Telnet downstream from an AP (from a registered SM) to modify system parameters. Setting RF Telnet Access to “Disabled” does not affect devices situated above the AP from accessing the AP via Telnet, including servers running the CNUT (Canopy Network Updater tool) application. Also, setting RF Telnet Access to “Disabled” does not affect any Telnet access into upstream devices (situated above or adjacent to the AP) through the AP (see Figure 140). The figure below depicts a user attempting two telnet sessions. One is targeted for the AP (orange) and one is targeted for the network upstream from the AP (green). If RF Telnet Access is set to “Disabled” (factory default setting), the Telnet attempt from the user to the AP is blocked, but the attempt from the user to Network is allowed to pass through the Cambium network. Figure 140 RF Telnet Access Restrictions (orange) and Flow through (green)
Chapter 7: Configuration Configuring security Page 7-111 Key Security Considerations when using the RF Telnet Access Feature To ensure that the network is fully protected from unauthorized AP Telnet sessions, the following topics must be considered: Securing AP Clusters When working with a cluster of AP units, to eliminate potential security holes allowing Telnet access, ensure that the RF Telnet Access parameter is set to “Disabled” for every AP in the cluster. In addition, since users situated below the AP are able to pass Telnet sessions up through the SM and AP to the upstream network (while AP RF Telnet Access is set to “Disabled”), ensure that all CMM4 or other networking equipment is secured with strong passwords. Otherwise, users may Telnet to the CMM4 or other networking equipment, and subsequently access network APs (see Figure 141) via their Ethernet interfaces (since RF Telnet Access only prevents Telnet sessions originating from the AP’s wireless interface). Figure 141 RF Telnet Access Restriction (orange) and Potential Security Hole (green) As a common practice, AP administrator usernames and passwords must be secured with strong, non-default passwords. Restricting AP RF Telnet Access AP Telnet access via the RF interface may be configured in two ways – the AP GUI and SNMP. Controlling RF Telnet Access via the AP GUI To restrict all Telnet access to the AP via the RF interface from downstream devices, follow these instructions using the AP GUI: Procedure 20 Restricting RF Telnet access 1 Log into the AP GUI using administrator credentials 2 On the AP GUI, navigate to Configuration > Protocol Filtering
Chapter 7: Configuration Configuring security Page 7-112 3 Under GUI heading “Telnet Access over RF Interface”, set RF Telnet Access to Disabled 4 Click the Save button 5 Once the Save button is clicked, all RF Telnet Access to the AP from devices situated below the AP is blocked. Note The factory default setting for RF Telnet Access is disabled and PPPoE PADI Downlink Forwarding is enabled.
Chapter 7: Configuration Configuring security Page 7-113 Configuring SNMP Access The SNMPv3 interface provides a more secure method to perform SNMP operations. This standard provides services for authentication, data integrity and message encryption over SNMP. Refer to Planning for SNMPv3 operation on page 3-43 for details. Note The factory default setting for SNMP is “SNMPv2c Only”. Procedure 21 Configuring SNMPv3 1 Log into the AP GUI using administrator credentials 2 On the AP/SM GUI, navigate to Configuration > Security Page 3 Under GUI heading “Security Mode”, set SNMP to SNMPv3 Only 4 Click the Save Changes button 5 Go to Configuration > SNMP Page 6 Under GUI heading “SNMPv3 setting”, set Engine ID, SNMPv3 Security Level, SNMPv3 Authentication Protocol, SNMPv3 Privacy Protocol, SNMPv3 Read-Only User, SNMPv3 Read/Write User, SNMPv3 Trap Configuration parameters:Engine ID : Each radio (AP/SM/BHM/BHS) has a distinct SNMP authoritative engine identified by a unique Engine ID. While the Engine ID is configurable to the operator it is expected that the operator follow the guidelines of the SNMPEngineID defined in the SNMP-FRAMEWORK-MIB (RFC 3411). The default Engine ID is the MAC address of the device. SNMPv3 security level, Authentication and Privacy Protocol The authentication allows authentication of SNMPv3 user and privacy allows for encryption of SNMPv3 message. 450 Platform Family supports MD5 authentication and CBC-DES privacy protocols.
Chapter 7: Configuration Configuring security Page 7-114 SNMPv3 Read-Only and Read/Write User The user can defined by configurable attributes. The attributes and default values are:  Read-only user o Username = Canopyro o Authentication Password = authCanopyro o Privacy Password = privacyCanopyro  Read-write user (by default read-write user is disabled) o Username = Canopy o Authentication Password = authCanopy o Privacy Password = privacyCanopy SNMPv3 Trap Configuration The traps may be sent from radios in SNMPv3 format based on parameter settings.

Chapter 7: Configuration Configuring security Page 7-116 Attribute Meaning Authentication Mode Operators may use this field to select from among the following authentication modes: Disabled—the AP/BHM requires no SMs/BHS to authenticate. (Factory default). Authentication Server —the AP/BHM requires any SM/BHS that attempts registration to be authenticated in Wireless Manager before registration. AP PreShared Key - The AP/BHM acts as the authentication server to its SMs/BHS and will make use of a user-configurable pre-shared authentication key. The operator enters this key on both the AP/BHM and all SMs/BHS desired to register to that AP/BHM. There is also an option of leaving the AP/BHM and SMs/BHS at their default setting of using the “Default Key”. Due to the nature of the authentication operation, if you want to set a specific authentication key, then you MUST configure the key on all of the SMs/BHS and reboot them BEFORE enabling the key and option on the AP/BHM. Otherwise, if you configure the AP/BHM first, none of the SMs/BHS is able to register. RADIUS AAA - When RADIUS AAA is selected, up to 3 Authentication Server (RADIUS Server) IP addresses and Shared Secrets can be configured. The IP address(s) configured here must match the IP address(s) of the RADIUS server(s). The shared secret(s) configured here must match the shared secret(s) configured in the RADIUS server(s). Servers 2 and 3 are meant for backup and reliability, not for splitting the database. If Server 1 doesn’t respond, Server 2 is tried, and then server 3. If Server 1 rejects authentication, the SM is denied entry to the network, and does not progress trying the other servers. Note This parameter is applicable to BHM.
Chapter 7: Configuration Configuring security Page 7-117 Authentication Server DNS Usage The management DNS domain name may be toggled such that the name of the authentication server only needs to be specified and the DNS domain name is automatically appended to that name. Note This parameter is applicable to BHM. Authentication Server 1 to 5 Enter the IP address or server name of the authentication server (RADIUS or WM) and the Shared Secret configured in the authentication server. When Authentication Mode RADIUS AAA is selected, the default value of Shared Secret is “CanopySharedSecret”. The Shared Secret may consist of up to 32 ASCII characters. Note This parameter is applicable to BHM. Radius Port This field allows the operator to configure a custom port for RADIUS server communication. The default value is 1812. Note This parameter is applicable to BHM. Authentication Key The authentication key is a 32-character hexadecimal string used when Authentication Mode is set to AP PreShared Key. By default, this key is set to 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF. Note This parameter is applicable to BHM. Select Key This option allows operators to choose which authentication key is used: Use Key above means that the key specified in Authentication Key is used for authentication Use Default Key means that a default key (based off of the SM’s MAC address) is used for authentication Note This parameter is applicable to BHM. Dynamic Authorization Extensions for RADIUS Enable CoA and Disconnect Message: Allows to control configuration parameters of SM using RADIUS CoA and Disconnect Message feature. Disable CoA and Disconnect Message: Disables RADIUS CoA and Disconnect Message feature. To enable CoA and Disconnect feature, the Authentication Mode should be set to RADIUS AAA. Bypass Authentication for ICC SMs Enabled: SM authentication is disabled when SM connects via ICC (Installation Color Code). Disabled: SM authentication is enabled. Encryption Setting Specify the type of airlink security to apply to this AP. The encryption setting must match the encryption setting of the SMs.

Phase 1 The protocols supported for the Phase 1 (Outside Identity) phase of authentication are EAPTTLS (Extensible Authentication Protocol Tunneled Transport Layer Security) or MSCHAPv2 (Microsoft Challenge-Handshake Authentication Protocol version 2).
Chapter 7: Configuration Configuring security Page 7-122 Phase 2 Select the desired Phase 2 (Inside Identity) authentication protocol from the Phase 2 options of PAP (Password Authentication Protocol), CHAP (Challenge Handshake Authentication Protocol), and MSCHAP (Microsoft’s version of CHAP, version 2 is used). The protocol must be consistent with the authentication protocol configured on the RADIUS server. Identity/Realm If Realms are being used, select Enable Realm and configure an outer identity in the Identity field and a Realm in the Realm field. These must match the Phase 1/Outer Identity and Realm configured in the RADIUS server. The default Identity is “anonymous”. The Identity can be up to 128 non-special (no diacritical markings) alphanumeric characters. The default Realm is “canopy.net”. The Realm can also be up to 128 non-special alphanumeric characters. Configure an outer Identity in the Username field. This must match the Phase 1/Outer Identity username configured in the RADIUS server. The default Phase 1/Outer Identity Username is “anonymous”. The Username can be up to 128 non-special (no diacritical markings) alphanumeric characters. Username Enter a Username for the SM. This must match the username configured for the SM on the RADIUS server. The default Username is the SM’s MAC address. The Username can be up to 128 non-special (no diacritical markings) alphanumeric characters. Password Enter the desired password for the SM in the Password and Confirm Password fields. The Password must match the password configured for the SM on the RADIUS server. The default Password is “password”. The Password can be up to 128 non-special (no diacritical markings) alphanumeric characters Upload Certificate File To upload a certificate manually to a SM, first load it in a known place on your PC or network drive, then click on a Delete button on one of the Certificate description blocks to delete a certificate to provide space for your certificate. Click on Choose File, browse to the location of the certificate, and click the Import Certificate button, and then reboot the radio to use the new certificate. When a certificate is in use, after the SM successfully registers to an AP, an indication of In Use will appear in the description block of the certificate being used. The public certificates installed on the SMs are used with the private certificate on the RADIUS server to provide a public/private key encryption system. Up to 2 certificates can be resident on a SM. An installed certificate can be deleted by clicking the Delete button in the certificate’s description block on the Configuration > Security tab. To restore the 2 default certificates, click the Use Default Certificates button in the RADIUS Certificate Settings parameter block and reboot the radio.
Chapter 7: Configuration Configuring security Page 7-123 Encryption Setting Specify the type of airlink security to apply to this SM. The encryption setting must match the encryption setting of the AP. None provides no encryption on the air link. DES (Data Encryption Standard): An over-the-air link encryption option that uses secret 56-bit keys and 8 parity bits. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES encryption does not affect the performance or throughput of the system. AES (Advanced Encryption Standard): An over-the-air link encryption option that uses the Rijndael algorithm and 128-bit keys to establish a higher level of security than DES. AES products are certified as compliant with the Federal Information Processing Standards (FIPS 197) in the U.S.A. Web, Telnet, FTP Session Timeout Enter the expiry in seconds for remote management sessions via HTTP, telnet, or FTP access to the SM.

Chapter 7: Configuration Configuring radio parameters Page 7-128 PMP 450m Series – configuring radio Radio page - PMP 450m AP 5 GHz The Radio tab of the PMP 450m AP contains some of the configurable parameters that define how an AP operates. Note Only the frequencies available for your region and the selected Channel bandwidth are displayed. Table 141 PMP 450m AP Radio attributes - 5 GHz
Chapter 7: Configuration Configuring radio parameters Page 7-129 Attribute Meaning Frequency Band Select the desired operating frequency band. Frequency Carrier Specify the frequency for the module to transmit. The default for this parameter is None. For a list of channels in the band, see the drop-down list on the radio GUI. Channel Bandwidth The channel size used by the radio for RF transmission. The setting for the channel bandwidth must match between the AP and the SM. The supported Channel Bandwidths are 5MHz, 10 MHz, 15 MHz, 20 MHz, and 40 MHz. Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol to allow multi-pathing to settle before receiving the desired data. A 1/16 cyclic prefix means that for every 16 bits of throughput data transmitted, an additional bit is used. Color Code Specify a value from 0 to 254. For registration to occur, the color code of the SM and the AP must match. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. Color code allows you to force a SM to register to only a specific AP, even where the SM can communicate with multiple APs. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). Subscriber Color Code Rescan (When not on a Primary Color Code) This timer may be utilized to initiate SM rescans in order to register to an AP configured with the SM‘s primary color code. The time (in minutes) for a subscriber to rescan (if this AP is not configured with the SM‘s primary color code). This timer will only fire once – if the Subscriber Color Code Wait Period for Idle timer is configured with a nonzero value and the Subscriber Color Code Rescan expires, the Subscriber Color Code Wait Period for Idle is started. If the Subscriber Color Code Wait Period for Idle timer is configured with a zero value and the Subscriber Color Code Rescan timer expires, the SM will immediately go into rescan mode Subscriber Color Code Wait Period for Idle The time (in minutes) for a subscriber to rescan while idle (if this AP is not configured with the SM’s primary color code). This timer will fire periodic events. The fired event determines if any RF unicast traffic (either inbound or outbound) has occurred since the last event. If the results of the event determine that no RF unicast traffic has occurred (SM is idle), then the subscriber will rescan.
Chapter 7: Configuration Configuring radio parameters Page 7-130 Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. While the SM is accessible for configuration from above the AP (for remote provisioning) and below the SM (for local site provisioning), no user data is passed over the radio link. When using the Installation Color Code feature, ensure that the SM is configured with the factory default Color Code configuration (Color Code 1 is “0”, Color Code 2-10 set to “0” and “Disable”). The status of the Installation Color Code can be viewed on the AP Eval web GUI page, and when the SM is registered using the Installation Color Code the message “SM is registered via ICC – Bridging Disabled!” is displayed in red on every SM GUI page. The Installation Color Code parameter is configurable without a radio reboot for both the AP and SM. If a SM is registered via Installation Color Code and the feature is then disabled, operators will need to reboot the SM or force it to reregister (i.e. using Rescan APs functionality on the AP Eval page). Max Range Enter a number of miles (or kilometers divided by 1.61, then rounded to an integer) for the furthest distance from which a SM is allowed to register to this AP. Do not set the distance to any greater number of miles. A greater distance  does not increase the power of transmission from the AP.  can reduce aggregate throughput. For example, with a 20 MHz channel and 2.5 ms frame, every additional 2.24 miles reduces the data air time by one symbol (around 1% of the frame). Regardless of this distance, the SM must meet the minimum requirements for an acceptable link. The parameters have to be selected so that there is no overlap between one AP transmitting and another AP receiving. A co-location tool is provided to help with selecting sets of parameters that allow co-location. The default value of this parameter is 2 miles (3.2 km). Downlink Data Specify the percentage of the aggregate throughput for the downlink (frames transmitted from the AP to the subscriber). For example, if the aggregate (uplink and downlink total) throughput on the AP is 90 Mb, then 75% specified for this parameter allocates 67.5 Mb for the downlink and 22.5 Mb for the uplink. The default for this parameter is 75%. This parameter must be set in the range of 15% - 85%, otherwise the invalid input will not be accepted and the previously-entered valid setting is used. Note In order to prevent self-interference, the frame configuration needs to align which includes Downlink Data, Max Range and Contention slots. For DFS regions, the maximum Downlink % for a 5.4 GHz radio is 75% only. Contention Slots (a.k.a. Control Slots) This field indicates the number of (reserved) Contention slots configured by the operator. The SM uses reserved Contention slots and unused data slots for bandwidth requests. See Contention slots on page 7-176.
Chapter 7: Configuration Configuring radio parameters Page 7-131 EIRP This field indicates the combined power level at which the AP will transmit, based on the Country Code. It also includes the antenna gain and array gain. SM Receive Target Level Each SM’s Transmitter Output Power is automatically set by the AP. The AP monitors the received power from each SM, and adjusts each SM’s Transmitter Output Power so that the received power at the AP from that SM is not greater what is set in this field. This value represents the transmitted and received power (combined power) perceived on the SM. Receive Quality Debug To aid in link performance monitoring, the AP and SM now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM and 256-QAM) and per channel (polarization). Note Due to CPU load, this will slightly degrade packet per second processing. Near Field Operation This parameter is enabled by the Near Field Operation control. This is only available when the EIRP is set to 22 dBm or below. When Near Field Operation is enabled, the Near Field Range is used to apply compensation to the unit’s calibration to support operation in the near field.

Chapter 7: Configuration Configuring radio parameters Page 7-135 Contention Slots (a.k.a. Control Slots) This field indicates the number of (reserved) Contention slots configured by the operator. The SM uses reserved Contention slots and unused data slots for bandwidth requests. See Contention slots on page7-176. Broadcast Repeat Count The default is 2 repeats (in addition to the original broadcast packet, for a total of 3 packets sent for every one needed), and is settable to 1 or 0 repeats (2 or 1 packets for every broadcast). ARQ (Automatic Repeat reQuest) is not present in downlink broadcast packets, since it can cause unnecessary uplink traffic from every SM for each broadcast packet. For successful transport without ARQ, the AP repeats downlink broadcast packets. The SMs filter out all repeated broadcast packets and, thus, do not transport further. The default of 2 repeats is optimum for typical uses of the network as an internet access system. In applications with heavy download broadcast such as video distribution, overall throughput is significantly improved by setting the repeat count to 1 or 0. This avoids flooding the downlink with repeat broadcast packets. Transmitter Output Power This value represents the combined power of the AP’s two transmitters. Nations and regions may regulate transmitter output power. For example  900 MHz, 5.4 GHz and 5.8 GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. The professional installer of the equipment has the responsibility to  maintain awareness of applicable regulations.  calculate the permissible transmitter output power for the module.  confirm that the initial power setting is compliant with national or regional regulations.  confirm that the power setting is compliant following any reset of the module to factory defaults. External Gain This value needs to correspond to the published gain of the antenna used to ensure the radio will meet regulatory requirements. SM Receive Target Level See Table 141 PMP 450m AP Radio attributes - 5 GHz on page 7-127 Multicast VC Data Rate This pull down menu of the Multicast Data Control screen helps in configuring multicast packets to be transmitted over a dedicated channel at a configurable rate of 1X, 2X, 4X or 6X. The default value is “Disable”. If set to the default value, all multicast packets are transmitted over the Broadcast VC data path. This feature is available only for the PMP 450 Series and is not backward compatible with PMP 430 series of radios.
Chapter 7: Configuration Configuring radio parameters Page 7-136 Multicast Repeat Count This value is the number of packets that are repeated for every multicast VC packet received on the AP (located under Radio tab of Configuration). Multicast (like Broadcast) packets go over a VC that is shared by all SMs, so there is no guaranteed delivery. The repeat count is an attempt to improve the odds of the packets getting over the link. If the user has issues with packets getting dropped, they can use this parameter to improve the performance at the cost of the overall throughput possible on that channel. The default value is 0. Multicast Downlink CIR This value is the committed information rate for the multicast downlink VC (located under the Radio tab of Configuration). The default value is 0 kbps. The range of this parameter is based on the number of repeat counts. The higher the repeat count, the lower the range for the multicast downlink CIR. SM Registration All This field allows to control registration of all type 450 Platform Family SM including 430 Series SM(450i/450/430) or 450i Series SM only. PMP 430 SM Registration This field allows to control of PMP 430 SMs whether PMP 430 SMs are allowed to register to PMP 450i APs. By default, it is enabled and PMP 430 SM registrations are accepted. When this field is set to disabled, PMP 430 SM’s registrations fail with reject reason 8. This will cause SMs to lock out the AP for 15 minutes. Note This option is not displayed if the Frame Period is set to 5 ms. This option applies only to PMP 450/450i Series APs - 5 GHz. Control Message Controls whether the control messages are sent in MIMO-B or MIMO-A mode. MIMO-A is recommended. However, if an AP on 13.2 is attempting to connect to an SM on 13.1.3 or before, changing to MIMO-B may aid in getting the SM registered. PMP 450/430 Legacy mode Disabled: It is factory default setting. It allows to operate in 450i Series capabilities. Enabled: It allows to operate radio in Legacy mode PMP 450 or 430. PMP 430 Interop Mode For n-1 compatibility, In SISO mode this forces the AP to only send Control and Beacons over one of the RF paths. Receive Quality Debug To aid in link performance monitoring, the AP and SM now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM) and per channel (polarization). Note Due to CPU load, this will slightly degrade packet per second processing. Frame Alignment Legacy Mode Mode Behavior (non-900 MHz radios) Behavior (FSK 900 MHz radios)

Chapter 7: Configuration Configuring radio parameters Page 7-142 Attribute Meaning Custom Radio Frequency Scan Selection List Check the frequencies that SM has to scan for AP transmissions. See Radio Frequency Scan Selection List on page 7-169. Channel Bandwidth Scan The channel size used by the radio for RF transmission. Note Selecting multiple channel bandwidths will increase registration and re-registration times. Cyclic Prefix Scan The cyclic prefix for which AP scanning is executed. AP Selection Method Operators may configure the method by which a scanning SM selects an AP. By default, AP Selection Method is set to “Optimize for Throughput”, which has been the mode of operation in releases prior to 12.0.3.1. Power Level: AP selection based solely on power level Note For operation with a PMP 450m AP, select the Power Level option or Optimize for Throughput: AP selection based on throughput optimization – the selection decision is based on power level (which affects the modulation state), channel bandwidth (which affects throughput) and number of SM registrations to the AP (which affects system contention performance). Color Code 1 Color code allows you to force the SM to register to only a specific AP, even where the SM can communicate with multiple APs. For registration to occur, the color code of the SM and the AP must match. Specify a value from 0 to 254. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). SMs may be configured with up to 20 color codes. These color codes can be tagged as Primary, Secondary, or Tertiary, or Disable. When the SM is scanning for APs, it will first attempt to register to an AP that matches one of the SM’s primary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM’s secondary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM’s tertiary color codes. This is all done in the scanning mode of the SM and will repeat until a registration has occurred.
Chapter 7: Configuration Configuring radio parameters Page 7-143 Color codes in the same priority group are treated equally. For example, all APs matching one of the SM’s primary color codes are analyzed equally. Likewise, this evaluation is done for the secondary and tertiary groups in order. The analysis for selecting an AP within a priority group is based on various inputs, including signal strength and number of SMs already registered to each AP. The first color code in the configuration is the pre-Release 9.5 color code. Thus, it is always a primary color code for legacy reasons. The color codes can be disabled, with the exception of the first color code. Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. When using the Installation Color Code feature, ensure that the SM is configured with the factory default Color Code configuration (Color Code 1 is “0”, Color Code 2-10 set to “0” and “Disable”). The status of the Installation Color Code can be viewed on the AP Eval web GUI page, and when the SM is registered using the Installation Color Code the message “SM is registered via ICC – Bridging Disabled!” is displayed in red on every SM GUI page. The Installation Color Code parameter is configurable without a radio reboot for both the AP and SM. External Gain This value represents the antenna gain. For ODUs with integrated antenna, this is set at the correct value in the factory. For Connectorized ODUs with external antenna, the user must set this value to the overall antenna gain, including any RF cable loss between the ODU and the antenna. Large VC data Queue SM and BH have a configurable option used to prevent packet loss in the uplink due to bursting IP traffic. This is designed for IP burst traffic particular to video surveillance applications. Receive Quality Debug To aid in link performance monitoring, the AP and SM now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM) and per channel (polarization). Note Due to CPU load, this will slightly degrade packet per second processing. Note The frequencies that a user can select are controlled by the country or a region and the Channel Bandwidth selected. There can be a case where a user adds a custom frequency (from the Custom Frequencies page on page 7-172) and cannot see it in the pull down menu.

The Pager signals typically operate in the 928-930 frequency range. When the filter is enabled, the signals of 920 MHz and above are attenuated which enables better reception of signals in the rest of the band. Note that the AP/SM should not be configured on the frequencies of 920 MHz and above when this filter is enabled.

Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol to allow multi-pathing to settle before receiving the desired data. A 1/16 cyclic prefix means that for every 16 bits of throughput data transmitted, an additional bit is used. Frame Period Select the Frame Period of the radio. The support Frame Periods are : 5 ms and 2.5 ms. Color Code Specify a value from 0 to 254. For registration to occur, the color code of the BHM and the BHS must match. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each link a different color code. Color code allows you to force a BHS to register to only a specific BHM. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). Large VC data Q Enable Large VC Q for applications that burst data high rates. Large Qs may decrease effective throughput for TCP application. Disable Large VC Q if application need not handle bursts of data. Large Qs may decrease effective throughput for TCP application. Downlink Data Specify the percentage of the aggregate throughput for the downlink (frames transmitted from the BHM to the subscriber). For example, if the aggregate (uplink and downlink total) throughput on the BHM is 132 Mbps, then 75% specified for this parameter allocates 99 Mbps for the downlink and 33 Mbps for the uplink. The default for this parameter is 50%. This parameter must be set in the range of 15% - 85%, otherwise the invalid input will not be accepted and the previously-entered valid setting is used. Note In order to prevent self-interference, the frame configuration needs to align. This includes Downlink Data, Max Range and Contention slots. Transmit Power This value represents the combined power of the BHM’s two transmitters. Nations and regions may regulate transmit power. For example  PTP 450i Series modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance.
Chapter 7: Configuration Configuring radio parameters Page 7-148 The professional installer of the equipment has the responsibility to:  Maintain awareness of applicable regulations.  Calculate the permissible transmitter output power for the module.  Confirm that the initial power setting is compliant with national or regional regulations. Confirm that the power setting is compliant following any reset of the module to factory defaults. External Gain This value needs to correspond to the published gain of the antenna used to ensure the radio will meet regulatory requirements. Receive Quality Debug To aid in link performance monitoring, the BHM and BHS now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM and 256-QAM) and per channel (polarization). Note Due to CPU load, this slightly degrades the packet during per second processing. Frame Alignment Legacy Mode See Table 142 PMP 450i AP Radio attributes - 5 GHz on page 7-132.

Chapter 7: Configuration Configuring radio parameters Page 7-150 Attribute Meaning Custom Radio Frequency Scan Selection List Check any frequency that you want the BHS to scan for BHM transmissions. See Radio Frequency Scan Selection List on page 7-169. Channel Bandwidth Scan The channel size used by the radio for RF transmission. Note Selecting multiple channel bandwidths will increase registration and re-registration times.
Chapter 7: Configuration Configuring radio parameters Page 7-151 Cyclic Prefix Scan The cyclic prefix for which BHM scanning is executed. Color Code Color code allows to force the BHS to register to only a specific BHM, even where the BHS can communicate with multiple BHMs. For registration to occur, the color code of the BHS and the BHM must match. Specify a value from 0 to 254. The color codes can be disabled, with the exception of the first color code. Large VC data Q BHM and BHS have a configurable option used to prevent packet loss in the uplink due to bursting IP traffic. This is designed for IP burst traffic particular to video surveillance applications.

Chapter 7: Configuration Configuring radio parameters Page 7-154 Attribute Meaning Custom Radio Frequency Scan Selection List Check the frequencies that SM has to scan for AP transmissions. See Radio Frequency Scan Selection List on page 7-169. Channel Bandwidth Scan The channel size used by the radio for RF transmission. Note Selecting multiple channel bandwidths will increase registration and re-registration times. Cyclic Prefix Scan The cyclic prefix for which AP scanning is executed. AP Selection Method Operators may configure the method by which a scanning SM selects an AP. By default, AP Selection Method is set to “Optimize for Throughput”, which has been the mode of operation in releases prior to 12.0.3.1. Power Level: AP selection based solely on power level Note For operation with a PMP 450m AP, select the Power Level option or Optimize for Throughput: AP selection based on throughput optimization – the selection decision is based on power level (which affects the modulation state), channel bandwidth (which affects throughput) and number of SM registrations to the AP (which affects system contention performance). Color Code 1 Color code allows you to force the SM to register to only a specific AP, even where the SM can communicate with multiple APs. For registration to occur, the color code of the SM and the AP must match. Specify a value from 0 to 254. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). SMs may be configured with up to 20 color codes. These color codes can be tagged as Primary, Secondary, or Tertiary, or Disable. When the SM is scanning for APs, it will first attempt to register to an AP that matches one of the SM’s primary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM’s secondary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM’s tertiary color codes. This is all done in the scanning mode of the SM and will repeat until a registration has occurred.
Chapter 7: Configuration Configuring radio parameters Page 7-155 Color codes in the same priority group are treated equally. For example, all APs matching one of the SM’s primary color codes are analyzed equally. Likewise, this evaluation is done for the secondary and tertiary groups in order. The analysis for selecting an AP within a priority group is based on various inputs, including signal strength and number of SMs already registered to each AP. The first color code in the configuration is the pre-Release 9.5 color code. Thus, it is always a primary color code for legacy reasons. The color codes can be disabled, with the exception of the first color code. Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. When using the Installation Color Code feature, ensure that the SM is configured with the factory default Color Code configuration (Color Code 1 is “0”, Color Code 2-10 set to “0” and “Disable”). The status of the Installation Color Code can be viewed on the AP Eval web GUI page, and when the SM is registered using the Installation Color Code the message “SM is registered via ICC – Bridging Disabled!” is displayed in red on every SM GUI page. The Installation Color Code parameter is configurable without a radio reboot for both the AP and SM. External Gain This value represents the antenna gain. For ODUs with integrated antenna, this is set at the correct value in the factory. For Connectorized ODUs with external antenna, the user must set this value to the overall antenna gain, including any RF cable loss between the ODU and the antenna. Large VC data Queue SM and BH have a configurable option used to prevent packet loss in the uplink due to bursting IP traffic. This is designed for IP burst traffic particular to video surveillance applications. Receive Quality Debug To aid in link performance monitoring, the AP and SM now report the number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM) and per channel (polarization). Note Due to CPU load, this will slightly degrade packet per second processing. Note The frequencies that a user can select are controlled by the country or a region and the Channel Bandwidth selected. There can be a case where a user adds a custom frequency (from the Custom Frequencies page on page 7-172) and cannot see it in the pull down menu.
