I have cisco catalyst switch and i want to configure port mirroring on that. For that i configured the switch using following :
Switch(config)# monitor session 1 source interface gigabitethernet0/1
Switch(config)# monitor session 1 destination interface gigabitethernet0/2
But after this configuration my switch show line protocol down for monitored interfaces.Please provide your valuable suggestion to get this resolve.
I also want to know how to test whether I'm getting mirrored traffic on monitored port?
I'm trying it with wireshark.
