Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 251 18.1.6 Security Tab of the AP An example of the Security tab of the AP is displayed in Figure 86. Figure 86: Security tab of AP, example In the Security tab of the AP, you may set the following parameters. Authentication Mode If the AP has authentication capability, then you can use this field to select from among the following authentication modes: ◦ Authentication Disabled—the AP requires no SMs to authenticate.
Installation and Configuration Guide Release 8 252 Draft 2 for Regulatory Review Issue 2, December 2006 ◦ Authentication Required—the AP requires any SM that attempts registration to be authenticated in BAM or Prizm before registration. If the AP does not have authentication capability, then this parameter displays Authentication Not Available. Authentication Server 1 to 3 If either BAM or the BAM subsystem in Prizm is implemented and the AP has authentication capability, enter the IP address of one or more BAM servers that perform authentication for SMs registered to this AP. Enter these in order of primary, secondary, then tertiary. Encryption Specify the type of air link security to apply to this AP: ◦ Encryption Disabled provides no encryption on the air link. This is the default mode. ◦ Encryption Enabled provides encryption, using a factory-programmed secret key that is unique for each module. Encrypt Downlink Broadcast When Encryption Enabled is selected in the Airlink Security parameter (described above) and Enable is selected in the Encrypt Downlink Broadcast parameter, the AP encrypts downlink broadcast packets as ◦ DES where the AP is DES capable. ◦ AES where the AP is AES capable. For more information about the Encrypt Downlink Broadcast feature, see Encrypting Downlink Broadcasts on Page 380. SM Display of AP Evaluation Data You can use this field to suppress the display of data about this AP on the AP Evaluation tab of the Tools page in all SMs that register. Web, Telnet, FTP Session Timeout Enter the expiry in seconds for remote management sessions via HTTP, telnet, or ftp access to the AP. IP Access Control You can permit access to the AP from any IP address (IP Access Filtering Disabled) or limit it to access from only one, two, or three IP addresses that you specify (IP Access Filtering Enabled). If you select IP Access Filtering Enabled, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted from any IP address, including access and management by Prizm. Allowed Source IP 1 to 3 If you selected IP Access Filtering Enabled for the IP Access Control parameter, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted to the AP from any IP address. You may populate as many as all three. If you selected IP Access Filtering Disabled for the IP Access Control parameter, then no entries in this parameter are read, and access from all IP addresses is permitted.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 253 The Security tab of the AP also provides the following buttons. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented. 18.1.7 VLAN Tab of the AP An example of the AP VLAN tab is displayed in Figure 87. Figure 87: VLAN tab of AP, example In the VLAN tab of the AP, you may set the following parameters. VLAN Specify whether VLAN functionality for the AP and all linked SMs should (Enabled) or should not (Disabled) be allowed. The default value is Disabled.
Installation and Configuration Guide Release 8 254 Draft 2 for Regulatory Review Issue 2, December 2006 Dynamic Learning Specify whether the AP should (Enabled) or should 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. Allow Frame Types Select the type of arriving frames that the AP should tag, using the VID that is stored in the Untagged Ingress VID parameter. The default value is All Frames. VLAN Aging Timeout Specify how long the AP should 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. SM Management VID Pass-through Specify whether to allow the SM (Enable) or the AP (Disable) to control the VLAN settings of this SM. The default value is Enable. CAUTION! Do not set this parameter to Enable where both ◦ a BAM release earlier than 2.1 is implemented. ◦ the Configuration Source parameter in the AP is set to BAM. This combination causes the SMs to become unmanageable, until you gain direct access with an override plug and remove this combination from the AP configuration. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 255 18.1.8 VLAN Membership Tab of the AP An example of the VLAN Membership tab of the AP is displayed in Figure 88.

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.
Installation and Configuration Guide Release 8 256 Draft 2 for Regulatory Review Issue 2, December 2006 18.1.9 DiffServe Tab of the AP An example of the DiffServe tab of the AP is displayed in Figure 89. Figure 89: DiffServe tab of AP, example
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 257 You may set the following DiffServe tab parameters. CodePoint 1 through CodePoint 47 CodePoint 49 through CodePoint 55 CodePoint 57 through CodePoint 63 The default priority value for each settable CodePoint is shown in Figure 119. 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). You 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 for all downlinks within the sector and in the SM for each uplink. See DSCP Field on Page 89. The DiffServe tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented.
Installation and Configuration Guide Release 8 258 Draft 2 for Regulatory Review Issue 2, December 2006 18.1.10 Unit Settings Tab of the AP An example of the Unit Settings tab of the AP is shown in Figure 90. Figure 90: Unit Settings tab of AP, example The Unit Settings tab of the AP contains an option for how the AP should react when it detects a connected override plug. You may set this option as follows. Set to Factory Defaults Upon Default Plug Detection If Enabled is checked, then an override/default plug functions as a default plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all parameter values are reset to defaults. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug cannot see or learn the settings that were previously configured in it. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the default values for any that were not. If Disabled is checked, then an override/default plug functions as an override plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all previously configured parameter values remain and are displayed. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug can see and learn the settings. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the previous values for any that were not. See Overriding Forgotten IP Addresses or Passwords on AP, SM, or BH on Page 375. The Unit Settings tab also contains the following buttons.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 259 Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented. Undo Unit-Wide Saved Changes When you click this button, any changes that you made in any tab but did not commit by a reboot of the module are undone. Set to Factory Defaults When you click this button, all configurable parameters on all tabs are reset to the factory settings. 18.2 CONFIGURING AN SM FOR THE DESTINATION If an ADMINISTRATOR-level password has been set in the SM, you must log into the module before you can configure its parameters. See Managing Module Access by Passwords on Page 373.
Installation and Configuration Guide Release 8 260 Draft 2 for Regulatory Review Issue 2, December 2006 18.2.1 General Tab of the SM An example of a General tab in the SM is displayed in Figure 91. Figure 91: General tab of SM, example In the General tab of the SM, you may set the following parameters. Link Speeds Specify the type of link speed for the Ethernet connection. The default for this parameter is that all speeds are selected. The recommended setting is a single speed selection for all APs, BHs, and SMs in the operator network.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 261 802.3 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. 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. 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 should be a longer period than the ARP (Address Resolution Protocol) cache timeout of the router that feeds the network. 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. CAUTION! An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. SM Power Up Mode With No 802.3 Link Specify the default mode in which this SM will power up when the SM senses no Ethernet link. Select either ◦ Power Up in Aim Mode—the SM boots in an aiming mode. When the SM senses an Ethernet link, this parameter is automatically reset to Power Up in Operational Mode. When the module senses no Ethernet link within 15 minutes after power up, the SM carrier shuts off. ◦ Power Up in Operational Mode—the SM boots in Operational mode. The module attempts registration. Unlike in previous releases, this is the default selection in Release 8. 2X Rate Disable this parameter to facilitate initial aiming from the destination. Then see 2X Operation on Page 91.
Installation and Configuration Guide Release 8 262 Draft 2 for Regulatory Review Issue 2, December 2006 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. See Wiring to Extend Network Sync on Page 369. The General tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented. 18.2.2 NAT and IP Tabs of the SM with NAT Disabled An example of the NAT tab in an SM with NAT disabled is displayed in Figure 92.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 263 Figure 92: NAT tab of SM with NAT disabled, example This implementation is illustrated in Figure 46 on Page 157. In the NAT tab of an SM with NAT disabled, you may set the following parameters.
Installation and Configuration Guide Release 8 264 Draft 2 for Regulatory Review Issue 2, December 2006 NAT Enable/Disable This parameter enables or disabled the Network Address Translation (NAT) feature for the SM. NAT isolates devices connected to the Ethernet/wired side of an 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/wired side of the SM. For further information, see Network Address Translation (NAT) on Page 156 and NAT and IP Tabs of the SM with NAT Enabled on Page 268. NAT Private Network Interface Configuration, IP Address This parameter is not configurable when NAT is disabled.

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 1440 minutes (24 hours). 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. DHCP Client Enable/Disable This parameter is not configurable when NAT is disabled. DHCP Server Enable/Disable This parameter is not configurable when NAT is disabled. DHCP Server Lease Timeout This parameter is not configurable when NAT is disabled. DNS IP Address This parameter is not configurable when NAT is disabled. Preferred DNS IP Address This parameter is not configurable when NAT is disabled. Alternate DNS IP Address This parameter is not configurable when NAT is disabled. The NAT tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module.

Installation and Configuration Guide Release 8 266 Draft 2 for Regulatory Review Issue 2, December 2006 Figure 93: IP tab of SM with NAT disabled, example This implementation is illustrated in Figure 46 on Page 157. In the IP tab of an SM with NAT disabled, you may set the following parameters. LAN1 Network Interface Configuration, 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 set and then forget this parameter, then you must both 1. physically access the module. 2. use an override plug to electronically access the module configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses or Passwords on AP, SM, or BH on Page 377. RECOMMENDATION: 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.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 267 LAN1 Network Interface Configuration, Network Accessibility Specify whether the IP address of the SM should be visible to only a device connected to the SM by Ethernet (Local) or should be visible to the AP as well (Public). LAN1 Network Interface Configuration, Subnet Mask Enter an appropriate subnet mask for the SM to communicate on the network. The default subnet mask is 255.255.0.0. See Allocating Subnets on Page 162. LAN1 Network Interface Configuration, Gateway IP Address Enter the appropriate gateway for the SM to communicate with the network. The default gateway is 169.254.0.0. LAN1 Network Interface Configuration, 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. The IP tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented.

An example of the IP tab in an SM with NAT enabled is displayed in Figure 95. 18.2.4 Radio Tab of the SM An example of the Radio tab in the SM is displayed in Figure 96. Figure 96: Radio tab of SM, example In the Radio tab of the SM, you may set the following parameters. Custom Radio Frequency Scan Selection List Check any frequency that you want the SM to scan for AP transmissions. The frequency band of the SM affects what channels you should select.
Installation and Configuration Guide Release 8 274 Draft 2 for Regulatory Review Issue 2, December 2006 IMPORTANT! In the 2.4-GHz frequency band, the SM can register to an AP that transmits on a frequency 2.5 MHz higher than the frequency that the SM receiver locks when the scan terminates as successful. This establishes a poor-quality link. To prevent this, select frequencies that are at least 5 MHz apart. In a 2.4-GHz SM, this parameter displays all available channels, but has only three recommended channels selected by default. See 2.4-GHz AP Cluster Recommended Channels on Page 137. In a 5.2- or 5.4-GHz SM, this parameter displays only ISM frequencies. In a 5.7-GHz SM, this parameter displays both ISM and U-NII frequencies. If you select all frequencies that are listed in this field (default selections), then the SM scans for a signal on any channel. If you select only one, then the SM limits the scan to that channel. Since the frequencies that this parameter offers for each of these two bands are 5 MHz apart, a scan of all channels does not risk establishment of a poor-quality link as in the 2.4-GHz band. A list of channels in the band is provided in Considering Frequency Band Alternatives on Page 136. (The selection labeled Factory requires a special software key file for implementation.) Color Code 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. On all Canopy modules, the default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). RECOMMENDATION: Note the color code that you enter. Ensure that you can readily associate this color code both with the module and with the other data that you store about the module. External Filters Delay This parameter is present in only 900-MHz modules and can have effect in only those that have interference mitigation filter(s). If this value is present, leave it set to 0, regardless of whether the SM has an interference mitigation filter.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 275 Transmitter Output Power Nations and regions may regulate transmitter output power. For example ◦ Both 900-MHz and 5.7-GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. In addition to setting the power in the 5.7-GHz connectorized module, the operator must set the antenna gain/cable loss such that the module can accurately report received power at the antenna. ◦ Legal maximum allowable transmitter output power and EIRP (Equivalent Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and region. The output power of Series P9 2.4-GHz modules can be adjusted to meet these national or regional regulatory requirements. ◦ Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT member states, for example), generally require equipment using the band to have adjustable power. The professional installer of Canopy 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. For information on how to calculate the permissible transmitter output power to enter in this parameter, see Adjusting Transmitter Output Power on Page 326. The Radio tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory.

Installation and Configuration Guide Release 8 276 Draft 2 for Regulatory Review Issue 2, December 2006 18.2.5 SNMP Tab of the SM An example of the SNMP tab in an SM is displayed in Figure 97. Figure 97: SNMP tab of SM, example In the SNMP tab of the SM, you may set the following parameters. Community String Specify a control string that allows Prizm or an NMS (Network Management Station) to access MIB information about this SM. No spaces are allowed in this string. The default string is Canopy.
Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 277 The Community String value is clear text and is readable by a packet monitor. Additional security derives from the configuration of the Accessing Subnet, Trap Address, and Permission parameters. Accessing Subnet Specify the addresses that are allowed to send SNMP requests to this SM. Prizm or the NMS has an address that is among these addresses (this subnet). You must enter both ◦ The network IP address in the form xxx.xxx.xxx.xxx ◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx For example ◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits in the address range are identical among all members of the subnet). ◦ 192.168.102.0 specifies that any device whose IP address is in the range 192.168.102.0 to 192.168.102.254 can send SNMP requests to the SM, presuming that the device supplies the correct Community String value. The default treatment is to allow all networks access (set to 0). For more information on CIDR, execute an Internet search on “Classless Interdomain Routing.” RECOMMENDATION: The subscriber can access the SM by changing the subscriber device to the accessing subnet. This hazard exists because the Community String and Accessing Subnet are both visible parameters. To avoid this hazard, configure the SM to filter (block) SNMP requests. See Filtering Protocols and Ports on Page 378. Trap Address 1 to 10 Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which trap information should be sent. Trap information informs Prizm or an NMS that something has occurred. For example, trap information is sent ◦ after a reboot of the module. ◦ when Prizm or an NMS attempts to access agent information but either − supplied an inappropriate community string or SNMP version number. − is associated with a subnet to which access is disallowed. Read Permissions Select Read Only if you wish to disallow Prizm or NMS SNMP access to configurable parameters and read-only fields of the SM. Site Name Specify a string to associate with the physical module. This parameter is written into the sysName SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128 characters.
Installation and Configuration Guide Release 8 278 Draft 2 for Regulatory Review Issue 2, December 2006 Site Contact Enter contact information for the module administrator. This parameter is written into the sysContact SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128 characters. Site Location Enter information about the physical location of the module. This parameter is written into the sysLocation SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128 characters. The SNMP tab also provides the following buttons.

Release 8 Installation and Configuration Guide Issue 2, December 2006 Draft 2 for Regulatory Review 283 In the Security tab of the SM, you may set the following parameters. Authentication Key Only if the AP to which this SM will register requires authentication, specify the key that the SM should use when authenticating. For alpha characters in this hex key, use only upper case. Select Key The Use Default Key selection specifies the predetermined key for authentication in BAM or Prizm. See Authentication Manager Capability on Page 385. The Use Key above selection specifies the 32-digit hexadecimal key that is permanently stored on both the SM and the BAM or Prizm database. NOTE: The SM and BAM or Prizm pad the key of any length by the addition of leading zeroes, and if the entered keys match, authentication attempts succeed. However, Canopy recommends that you enter 32 characters to achieve the maximal security from this feature. Web, Telnet, FTP Session Timeout Enter the expiry in seconds for remote management sessions via HTTP, telnet, or ftp access to the SM. Ethernet Access Control If you want to prevent any device that is connected to the Ethernet port of the SM from accessing the management interface of the SM, select Ethernet Access Disabled. This selection disables access through this port to via http (the GUI), SNMP, telnet, ftp, and tftp. With this selection, management access is available through only the RF interface via either an IP address (if Network Accessibility is set to Public on the SM) or the Session Status or Remote Subscribers tab of the AP. NOTE: This setting does not prevent a device connected to the Ethernet port from accessing the management interface of other SMs in the network. To prevent this, use the IP Access Filtering Enabled selection in the IP Access Control parameter of the SMs in the network. See IP Access Control below. If you want to allow management access through the Ethernet port, select Ethernet Access Enabled. This is the factory default setting for this parameter. IP Access Control You can permit access to the SM from any IP address (IP Access Filtering Disabled) or limit it to access from only one, two, or three IP addresses that you specify (IP Access Filtering Enabled). If you select IP Access Filtering Enabled, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted from any IP address, including access and management by Prizm.
Installation and Configuration Guide Release 8 284 Draft 2 for Regulatory Review Issue 2, December 2006 Allowed Source IP 1 to 3 If you selected IP Access Filtering Enabled for the IP Access Control parameter, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted to the SM from any IP address. You may populate as many as all three. If you selected IP Access Filtering Disabled for the IP Access Control parameter, then no entries in this parameter are read, and access from all IP addresses is permitted. The Security tab of the SM also provides the following buttons. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory.

Installation and Configuration Guide Release 8 288 Draft 2 for Regulatory Review Issue 2, December 2006 In the DiffServe tab of the SM, you may set the following parameters. CodePoint 1 through CodePoint 47 CodePoint 49 through CodePoint 55 CodePoint 57 through CodePoint 63 The default priority value for each settable CodePoint is shown in Figure 119. 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). You 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 for all downlinks within the sector and in the SM for each uplink.

Figure 105: Unit Settings tab of SM, example The Unit Settings tab of the SM contains an option for how the SM should react when it detects a connected override plug. You may set this option as follows. Set to Factory Defaults Upon Default Plug Detection If Enabled is checked, then an override/default plug functions as a default plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all parameter values are reset to defaults. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug cannot see or learn the settings that were previously configured in it. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the default values for any that were not. If Disabled is checked, then an override/default plug functions as an override plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all previously configured parameter values remain and are displayed. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug can see and learn the settings. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the previous values for any that were not.

Where BAM, then SM is the indication, parameters for which BAM does not send values are obtained from the SM. This is the case where the BAM server is operating on a BAM release that did not support the feature. This is also the case where the feature enable/disable flag in BAM is set to disabled. The values are those previously set or, if none ever were, then the default values. Where BAM is the indication, values in the SM are disregarded. Where SM is the indication, values that BAM sends for the SM are disregarded. The high-priority channel is unavailable to Series P7 and P8 SMs that run Canopy Release 8. For any SM whose Authentication Mode parameter is not set to Authentication Required, the listed settings are derived as shown in Table 51.
Installation and Configuration Guide Release 8 294 Draft 2 for Regulatory Review Issue 2, December 2006 Table 51: Where feature values are obtained for an SM with authentication disabled Values are obtained from Configuration Source Setting in the AP MIR Values VLAN Values High Priority Channel State CIR Values BAM AP AP AP AP SM SM SM SM SM BAM+SM SM SM SM SM BAM Release 2.0 sends only MIR values. BAM Release 2.1 and Prizm Release 2.0 and 2.1 send VLAN and high-priority channel values as well. For the case where the Configuration Source parameter in the AP is set to BAM, the SM stores a value for the Dynamic Learning VLAN parameter that differs from its factory default. When Prizm does not send VLAN values (because VLAN Enable is set to No in Prizm), the SM ◦ uses this stored Disable value for Dynamic Learning. ◦ shows the following in the VLAN Configuration web page: − either Enable or Disable as the value of the Dynamic Learning parameter. − Allow Learning : No under Active Configuration. For the case where the Configuration Source parameter in the AP is set to BAM+SM, and Prizm does not send VLAN values, the SM ◦ uses the configured value in the SM for Dynamic Learning. If the SM is set to factory defaults, then this value is Enable. ◦ shows under Active Configuration the result of the configured value in the SM. For example, if the SM is set to factory defaults, then the VLAN Configuration page shows Allow Learning : Yes. This selection (BAM+SM) is not recommended where Prizm manages the VLAN feature in SMs. 18.4 CONFIGURING A BH TIMING MASTER FOR THE DESTINATION NOTE: The OFDM Series BHs are described in their own dedicated user guides. See Products Not Covered by This User Guide on Page 34. If an ADMINISTRATOR-level password has been set in the BHM, you must log into the module before you can configure its parameters.

Installation and Configuration Guide Release 8 296 Draft 2 for Regulatory Review Issue 2, December 2006 In the General tab of the BHM, you may set the following parameters. Timing Mode Select Timing Master. This BH will provide sync for the link. Whenever you toggle this parameter to Timing Master from Timing Slave, you should also do the following: 1. Make no other changes in this or any other interface page. 2. Save this change of timing mode. 3. Reboot the BH. RESULT: The set of interface web pages that is unique to a BHM is made available. Link Speeds Specify the type of link speed for the Ethernet connection. The default for this parameter is that all speeds are selected. The recommended setting is a single speed selection for all APs, BHs, and SMs in the operator network. Sync Input Specify the type of synchronization for this BH timing master to use. ◦ Select Sync to Received Signal (Power Port) to set this BHM to receive sync from a connected CMMmicro. ◦ Select Sync to Received Signal (Timing Port) to set this BHM to receive sync from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave. ◦ Select Generate Sync Signal where the BHM does not receive sync, and no AP or other BHM is active within the link range. 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 should 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. Bridging Functionality Select whether you want bridge table filtering active (Enable) or not (Disable) on this BHM. Selecting Disable allows you to use redundant BHs without causing network addressing problems. Through a spanning tree protocol, this reduces the convergence time from 25 minutes to mere seconds. However, you should disable bridge table filtering as only a deliberate part of your overall network design. Otherwise, disabling it allows unwanted traffic across the wireless interface.
