There is a limitation with port mirroring. A port channel cannot be the source for a mirror, this includes the physical ports in the port channel. You will find that if you get rid of the port channel the individual ports will be able to be mirrored.
Hi  I am using Dell P6448 is my access switch with Router on a stick architecture. There is a port-chennel between the dell switch and the router's LAN interfaces. Now my requirement is that I want to sniff all the traffic going on that port chennel on switch end and mirror it to some free port. Problem is once I configure moonitor session 1 source interface ? It gives option for physical interface only and port-chennel1 can not be specified there. Secondly if we try the physical ports in the source interface of monitor session command it gives an error that this port can not be used as source interface. I am using 3.3.1.10 Image. Thanks for the help in advance. Ashok Dhaktode
