All,


Is there any way to do a port span or tap of all traffic going to and from a WiSM?  You can't seem to monitor the port channel that goes into the controller.


Thanks

Sure, you can set the port-channel interface as the source of the monitor session.


lab1sup720ip1(config)#monitor session 1 source interface ?
  FastEthernet     FastEthernet IEEE 802.3
  GigabitEthernet  GigabitEthernet IEEE 802.3z
  Port-channel     Ethernet Channel of interfaces
