How does ClientMatch handle unsteerable clients?

QuestionHow does ClientMatch handle unsteerable clients?

 

Controller keeps track of successive steer failures for the respective steer reason
to the desired destination radio

Upon 5 consecutive failed steer attempts, controller notifies the associated AP
to mark the client as unsteerable (with reason)

AP will not attempt to steer that client for that specific reason (e.g. if a client is deemed
non band steerable, the AP can still continue to do a sticky health check rather than
completely overlooking the client)

Controller logs the client in a unsteerable list that can be read using
“show ap arm client-match unsupported”

Default Unsteerable client ageout 2880 mins


Example:

Enable debugging for the client:

#logging level debugging arm-user-debug <client-mac>


To Show the logs:
(Aruba3600) #show log arm 50 | include 18:46:17:eb:ab:40
