How does client match handle unsteerable clients?

Applicable for 6.2 and above ArubaOS which features ARM 3.0

 

Client Match – Handling 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:
