Switch(config)# end
Step 5
Creating a Local SPAN Session and Configuring Incoming Traffic
Beginning in privileged EXEC mode, follow these steps to create a SPAN session, to specify the source ports
or VLANs and the destination ports, and to enable incoming traffic on the destination port for a network
security device (such as a Cisco IDS Sensor Appliance).
SUMMARY STEPS
1.
configure terminal
2.
no monitor session {session_number | all | local | remote}
3.
monitor session session_number source {interface interface-id | vlan vlan-id} [, | -] [both | rx | tx]
4.
monitor session session_number destination {interface interface-id [, | -] [encapsulation replicate]
[ingress {dot1q vlan vlan-id | isl | untagged vlan vlan-id | vlan vlan-id}]}
