Environment : This article applies to Aruba Instant Access Points running InstantOS 3.4 and later.


Aruba Instant is a cluster architecture, where in all slave IAPs need continuous supply of master beacons from the IAP acting as Virtual Controller(VC). Delay in these beacons, cause the slave IAP to assume the current master is down and transition itself for an election of new master. This could cause if virtual controller allocates excessive CPU for Datapath and Management of associated clients, thereby delaying or queuing the master beacons. This is mainly observed in high client density environments.

To avoid these circumstances, InstantOS 3.4 introduces a feature to reserve Virtual Controller CPU for management and Control Plane functions.
Below screen shot from Instant GUI shows the Dynamic CPU Management options for specific environments:
