Standby APs on active table

By esupport posted Aug 05, 2020 09:19 AM

  
Q:

Does standby APs list comes in "active AP" table in a controller?



A:

This article applies to all controllers and APs supporting 8.x version.

Starting from 8.x version we will be able to see the standby APs on #show ap active table on the same controller if two or more controllers are present and only if clustering feature is enabled among them.

For example:

AP1’s AAC is controller 1,

AP2’s AAC is controller 2,

a client connect to AP2, and UAC is controller1.

When we perform the #show ap active command on controller 1, it will show both AP1 and AP2.

Verification:

 

On MD "Controller-2":

(Controller-2) [MDC] #show ap database-summary

On the above output we have 367 active tunnels. But when you check the #show ap active table you could see the total count as 649.

(MC7220-T2) [MDC] #show ap active | include Num

Num APs:649

 

When you verify the #show ap active table, it shows APs with standby flag and clients are connected to it. Below is an example.

 

(Controller-2) [MDC] #show ap active.    ( S indicates the standby flag)
