    Hello!

    How to enable port mirroring on a cisco router and can it be used for
    sniffing?

    It depends on what type of switch IOS or CatOS. For IOS try...

    monitor session 1 source interface FaX/X
    monitor session 1 destination interface FaX/X

    For CatOS try

    set span 2/1 3/1

    Good luck,
    -Jeff C
