Cisco Switch
Example below: Send a copy of traffic on fastethernet 0/1 to fastethernet 0/2. Traffic in both directions are mirrored.
SW1# configure terminal
SW1(config)# monitor session 1 source interface fastethernet0/1
SW1(config)# monitor session 1 destination interface fastethernet 0/2Remove mirror from session 1.
SW1# CONFIGURE TERMINAL
SW1(config)# no MONITOR SESSION 1Zyxel switch
Copy traffic from port 1,4,5 and 6 to port 3 (Note both means mirror traffic in both directions)
