Switch port mirroring is often used when sniffing traffic to/from a device. Se drawing below.
Cisco Switch
Example below: Send a copy of traffic on fastethernet 0/1 to fastethernet 0/2. Traffic in both directions are mirrored.
SW1# <input>configure terminal</input>
SW1(config)# <input>monitor session 1 source fastethernet0/1</input>
SW1(config)# <input>monitor session 1 destination fastethernet 0/2</input>Remove mirror from session 1.
SW1# <input>CONFIGURE TERMINAL</input>
SW1(config)# <input>no MONITOR SESSION 1</input>Zyxel switch
Copy traffic from port 1,4,5 and 6 to port 3
Switch(config)# <input>mirror-port</input>
Switch(config)# <input>mirror-port 3</input>
Switch(config)# <input>interface port-channel 1,4-6</input>
Switch(config-interface)# <input>mirror</input>
Switch(config-interface)# <input>mirror dir egress</input>Remove mirror again
Switch(config)# <input>no mirror-port</input>LG iPECS ES-3026P
From CLI
Monitor traffic in both directions on port 1/7 mirrorport 1/17
iPECS Ethernet Switch Administration
Username: <input>admin</input>

CLI session with the ES-3026P is opened.
To end the CLI session, enter [Exit].
