Step 1
Login to the CLI as outlined in “Connecting to the Subscriber Unit Command Line
Interface” on page 2-6.
Step 2
Enter the following command:
show bridgeFilter
This command is valid for software versions 2.0.21 and later. It replaces the command,
dlLearnFilter, available in earlier versions: The displayed value should be 1, indicating that
the bridge filter is enabled.
The Subscriber Unit Host Limitation
In addition to the operator-configured MAC limitation, the bridge filters impose a maximum
limit of 256 MAC addresses per SU. Additionally, a new host device must transmit traffic
upstream before any traffic will be permitted downstream to that host.
If you are experiencing connectivity issues with a specific host device, while other devices
are working as expected, use the following command to verify that the subscriber unit has
properly learned the host device's MAC:
Step 1
Login to the CLI as outlined in “Connecting to the Subscriber Unit Command Line
Interface” on page 2-6.
Step 2
Enter the following command:
show learnedHosts
You will see the MAC address of any CPE detected behind the subscriber unit. You can
also verify that detected number of host devices is less than or equal to the maximum
allowed.
Verifying the Host Devices from the Sector Controller
Verify that the host device has been properly provisioned on the sector controller by
issuing the same command on the sector controller, followed by the SU's MAC address.
Step 1
Login to the CLI as outlined in “Connecting to the Sector Controller Command Line
Interface” on page 2-5.
Step 2
Enter the following command:
show learnedHosts 00:09:02:03:ab:cd
Low Throughput
The first step in resolving poor subscriber unit throughput is to verify that device has a
functional wireless link. The link should be configured to allow the maximum data
throughout.
