Controller port bounce feature

Q:

Port bounce feature on controller.



A:

Support for Port bounce has been introduced in 8.2.x version. With this feature, the ports can be shutdown for upto 60 seconds (max) and wired clients can be forced to reconnect/reauthenticate. This can also be used to change the VLAN of the client by sending a CoA.

CoA (Change of Authorization) can be sent by any RADIUS server such as CPPM using the Aruba VSA: Aruba-Host-Port-Bounce.
The Disconnect Request contains the client mac address in the calling-stattion-id and can specify time for which the port has to be in shutdown state. Max value is 60 seconds.

If the value is specified as '0', the port is not shutdown.
