Configuring SPAN

The SPAN interface can be any interface on the switch as long as it's a static-access port. The SPAN port also has to reside in the same VLAN as the ports being monitored. To configure SPAN, follow these steps:

1. Once you are in exec mode, enter global configuration mode by typing configure terminal.

2. Enter interface <interface> to configure the interface that will act as the monitoring port.

3. Enter port monitor <interface> to enable port monitoring.

4. Enter end.

5. Enter show running config to verify your configuration.

6. To disable SPAN, follow the preceding steps but at step 3 put a no in front of the command.
