As i understand you have a router with G0/0 interface connecting to a switch on port 4/8


Choose a spare port on the switch which will act as the destination port (say 4 /12)


monitor session 1 source interface 4/8

monitor session 1 destination interface 4/12

Ah... so you have a switch module on the router


i dont think it is poosible to mirror the router fe ports to a switch module connected to the same router..

Perhaps I am not understanding something in your request. But port monitoring is a function done on a switch and not on a router. Does this router have a switch module installed as one of its cards?


Perhaps you can supply some additional detail about the router and about what you are trying to do, so that we can understand better and be able to give you better answers.

I think that you only can mirror the ports on the 16 ports wic module.

I do not believe that it is possible to mirror from a Gig interface of the router to a switch port on the switch module in the router. That is why the router does not accept the second command.
