How to mirror a switch port that belongs to Port-Channel interface?
Generally port mirroring allows ingress/egress packets on the port(s) to be mirrored. Starting 6.4 AOS version, it allows administrator to mirror port-channel interface. Assume you want to mirror "Port-channel 1" and send all monitored traffic to port 0/0/2 (the monitor port), CLI command as below,
(Aruba 7240) (config) #interface gigabitethernet 0/0/1
(Aruba 7240) (config-if)#port monitor port-channel ?
