an external antenna to PMP 450i Series, PMP 450 Series, PMP 450i Series AP 900 MHz
and PMP 450 Series SM
See Installing an integrated ODU on page 6-51
Align the AP as follows:
a. Move the module to where the link will be unobstructed by the radio horizon and
no objects penetrate the Fresnel zone.
b. Use a local map, compass, and/or GPS device as needed to determine the
direction that one or more APs require to each cover the intended 60° sector.
c.
Apply the appropriate degree of downward tilt.
d. Ensure that the nearest and furthest SMs that must register to this AP are within
the beam coverage area.
Adjust the azimuth to achieve visual alignment, lock the AP in the proper direction
and downward tilt.
Attach the cables to the AP (See Powering the AP/SM/BH for test configuration on
Page 5-17)

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 36 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.

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.
Remove 60 mm (2.5 inches) of the drop cable outer sheath.
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.
Fold the ground wire strap around the drop cable screen and fit cable ties.
Page 6-66
Chapter 6: Installation
Supplemental installation information
Tighten the cable ties with pliers. Cut the surplus from the cable ties.
Cut a 38mm (1.5 inches) section of self-amalgamating tape and wrap it completely around the
joint between the drop and ground cables.
Use the remainder of the self-amalgamating tape to wrap the complete assembly. Press the
tape edges together so that there are no gaps.
Page 6-67
Chapter 6: Installation
Supplemental installation information
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.
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.
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 antioxidant 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.

Supplemental installation information
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).
Ensure the connection is tight. A torque wrench should be used if available:
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:

below the edge of the self-amalgamating tape, overlapping at half width.
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.

Preparing for configuration
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 4-33.
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.

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 you 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 separate NTP server is addressable from the AP/BHM.
If the AP/BHM should obtain time and date from a CMM4, or a separate NTP server, enter the IP
address 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 through NTP.

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

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.

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.

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 1-27
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.
Page 7-33
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
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.
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.

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 DHCPassigned 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.
Page 7-40
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
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

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.

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

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

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.
Page 7-45
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
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 remarking 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:
Page 7-46
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
•
Promote IPv4/IPv6 priority – The priority in the IP header is copied to the Q-tag/C-tag.
•
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

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:

Header
S-VLAN
EthType 0x88a8
C-VLAN EthType
0x8100

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

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 00-00-00-00-0000 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 (Qin-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

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.

Configuring IP and Ethernet interfaces
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.
Page 7-60
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
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.

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
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.
CodePoint 49

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 (highpriority channel).
Page 7-62
Chapter 7: Configuration
Configuring IP and Ethernet interfaces
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.
CodePoint Select
This represents the CodePoint Selection to be modified via Priority

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.

Upgrading the software version and using CNUT
Upgrading the software version and using CNUT
This section consists of the following procedures:
•
Checking the installed software version on page 7-66
•
Upgrading to a new software version on page 7-66
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 4.11.2 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
Click on General tab under Home menu.
Note the installed Software Version (under Device Information):
PMP/PTP 450/450i/450m
Go to the support website (see Contacting Cambium Networks on page 1) and find Pointto-Multipoint software updates. Check that the latest 450 Platform Family software
version is the same as the installed Software Version.
To upgrade software to the latest version, see Upgrading to a new software version on
page 7-66.
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.
Page 7-66
Chapter 7: Configuration
Upgrading the software version and using CNUT
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.
Page 7-67
Chapter 7: Configuration
Upgrading the software version and using CNUT
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:
•
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
•

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:
Page 7-72
Chapter 7: Configuration
General configuration
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.
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.

Chapter 7: Configuration
Forward Unknown
Unicast Packets
General configuration
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

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.

•
A connected CMM4 passes time and date (GPS time and date, if

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 7-70).
PMP/PTP 450i Series has following synchronization options:
•
AutoSync
•
AutoSync + Free Run
•
Generate Sync
•
Free Run Before GPS Sync
Figure 140 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).
Page 7-99
Chapter 7: Configuration
Configuring synchronization
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.

Requiring SM Authentication
Applicable products

 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 7-116. For descriptions of each of the configurable security parameters on the
SM, see Security on page 7-121.
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 7-229.

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
3-44.

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).
