How can I setup a sniffer in 3750 switch? I would like to monitor a specific port. Is there a command like monitor port like this?
Switch(config-if)#interface fastethernet 0/4
Switch(config-if)#port monitor fastethernet 0/3
Thanks in advance.
Here's an example of the commands to setup a SPAN port.
monitor session 1 source interface Gi10/21
monitor session 1 destination interface Gi11/2
Hope that helps.
