Port Spanning on Cisco 2950

An example of a SPAN configuration on a Cisco 2950 Switch is below.

• Monitor session 1 source interface fastethernet 0/1, 0/2, 0/3
• Monitor session 1 destination interface fastethernet 0/4 encap ingress vlan 1

The above example mirrors data from ports 0/1, 0/2 and 0/3 to the destination port 0/4 using vlan1 for vlan tagging.

To show the status of a SPAN monitor session use the following command.

• show monitor session 1

Where 1 is the session number from the above statement.
