monitor session Chapter 2 IE 3000 Switch Cisco IOS Commands Examples • When you enter monitor session session_number destination interface interface-id encapsulation dot1q ingress, egress encapsulation uses the IEEE 802.1Q encapsulation method; ingress encapsulation depends on the keywords that follow-dot1q or untagged. (This applies to local SPAN only; RSPAN does not support encapsulation dot1q.) • When you enter monitor session session_number destination interface interface-id encapsulation replicate with no other keywords, egress encapsulation replicates the source interface encapsulation; ingress forwarding is not enabled. (This applies to local SPAN only; RSPAN does not support encapsulation replication.) • When you enter monitor session session_number destination interface interface-id encapsulation replicate ingress, egress encapsulation replicates the source interface encapsulation; ingress encapsulation depends on the keywords that follow-dot1q or untagged. (This applies to local SPAN only; RSPAN does not support encapsulation replication.) This example shows how to create a local SPAN session 1 to monitor both sent and received traffic on source port 1 to destination port 2: Switch(config)# monitor session 1 source interface gigabitethernet1/1 both Switch(config)# monitor session 1 destination interface gigabitethernet1/2 This example shows how to delete a destination port from an existing local SPAN session: Switch(config)# no monitor session 2 destination gigabitethernet1/2 This example shows how to limit SPAN traffic in an existing session only to specific VLANs: Switch(config)# monitor session 1 filter vlan 100 - 110 This example shows how to configure RSPAN source session 1 to monitor multiple source interfaces and to configure the destination RSPAN VLAN 900. Switch(config)# monitor session 1 source interface gigabitethernet1/1 Switch(config)# monitor session 1 source interface port-channel 2 tx Switch(config)# monitor session 1 destination remote vlan 900 Switch(config)# end This example shows how to configure an RSPAN destination session 10 in the switch receiving the monitored traffic. Switch(config)# monitor session 10 source remote vlan 900 Switch(config)# monitor session 10 destination interface gigabitethernet1/2 This example shows how to configure the destination port for ingress traffic on VLAN 5 by using a security device that supports IEEE 802.1Q encapsulation. Egress traffic replicates the source; ingress traffic uses IEEE 802.1Q encapsulation. Switch(config)# monitor session 2 destination interface gigabitethernet1/2 encapsulation replicate ingress dot1q vlan 5 This example shows how to configure the destination port for ingress traffic on VLAN 5 by using a security device that does not support encapsulation. Egress traffic and ingress traffic are untagged. Switch(config)# monitor session 2 destination interface gigabitethernet1/2 ingress untagged vlan 5 You can verify your settings by entering the show monitor privileged EXEC command. You can display SPAN and RSPAN configurations on the switch by entering the show running-config privileged EXEC command. SPAN information appears near the end of the output. 2-252 Cisco IE 3000 Switch Command Reference OL-13019-01
