Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands monitor session Examples This example shows how to create a local SPAN session 1 to monitor both sent and received traffic on source port 21 to destination port 22: Switch(config)# monitor session 1 source interface gigabitethernet0/21 both Switch(config)# monitor session 1 destination interface gigabitethernet0/22 This example shows how to delete a destination port from an existing local SPAN session: Switch(config)# no monitor session 2 destination gigabitethernet0/22 This example shows how to limit SPAN traffic in an existing session only to specific VLANs: Switch(config)# monitor session 1 filter vlan 100 - 304 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 gigabitethernet0/21 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 gigabitethernet0/22 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 gigabitethernet0/22 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 replicates the source encapsulation; ingress traffic is untagged. Switch(config)# monitor session 2 destination interface gigabitethernet0/22 encapsulation replicate ingress untagged vlan 5 You can verify your settings by entering the show monitor privileged EXEC command. You can display SPAN and RSPAN configuration on the switch by entering the show running-config privileged EXEC command. SPAN information appears near the end of the output. Related Commands Command remote-span show monitor show running-config Description Configures an RSPAN VLAN in vlan configuration mode. Displays SPAN and RSPAN session information. Displays the current operating configuration.
