Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands
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.
