Controller Based WLANs

How to push a random channel to the AP's on Aruba Controller running 8.0?
Requirement:
Random channel push helps in replacing the dynamic channel change solution in a high density environment, thereby overcoming the issue with convergence. Random channel assignment helps in certain customer deployments where administrators want to control channels assigned and also for initial channel assignment to seed ARM channel computation.


Solution:
We can push the random channel to the AP's in a specific group, we need to set the ARM Assignment to Maintain mode and execute the below command, random channels are pushed from the managed device STM/SAPM to APs that belong to a specific ap-group.


Configuration:
 
We need to execute the below command on the MD to push random channels to the AP's in a specific group which has the ARM in maintain mode.
(Local) *#
(Local) *#ap randomize-channel ap-group MainCampus phy-type 80211a
(Local) *#ap randomize-channel ap-group MainCampus phy-type 80211g
