6 Troubleshooting SU link from AP
This section will show you how to identify an SU that is having problem from an AP.
Identify SU
The hmm mac stats of the AP can identify that there is a problem in the sector, but is unable to identify
which SU is having a problem. Follow the steps below to identify which SU is having a problem.
1. To identify a problem SU you can use the pnms sector command which will give you 5 vital
statistics for each SU in the sector. You will be able to identify the SU that is having a problem by
the IP address. For more information on this command refer to PNMS Sector section.
2. Another command that can be used to identify an SU that is having problems is the bun list
channels command. This command displays the packet count on a per PVC basis. For more
information on this command refer to Bun list channels section. As you can see in the example
below the SU with MID 3 is having a small problem. The PVC 0/768 which is for MID 3 has
received 10 packets out of 168 with errors.
