Describing the command "#show ap remote bss-table <ap-name>"

Aruba Employee
Problem:

Sometimes end devices cannot see the SSIDs being broadcasted from the AP.

The AP show up as up on the controller:

#show ap database long

To check if the AP is broadcasting the SSID, we can check the BSS tables:

#show ap bss-table ap-name "AP1" 
Aruba AP BSS Table

bss                ess        port  ip             phy   type  ch/EIRP/max-EIRP  cur-cl  ap name   in-t(s)  tot-t          mtu   acl-state  acl  fm

Diagnostics:

however, the SSIDs are still not visible to end devices. Next we need to pull the BSS table information from the AP itself by using the following command:

 

#show ap remote bss-table ap-name "AP1" 
Device did not respond, please make sure the AM or AP IP is valid by issuing 'show ap bss-table'

 

Here we see that the BSS table is not retrievable from the AP. That is why the SSID was not visible to the end devices.



Solution

Summary:

# show ap bss-table <ap-name>                         : fetches the data from controller STM.

# show ap remote bss-table <ap-name>           : fetches the data from the AP
