Sniffer port in 3750 Switch

Hi Guys,

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.

Cheers!

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.
