Vlan Configuration Mode - Cisco Catalyst 3750 Metro Command Reference Manual

Chapter 2 Catalyst 3750 Metro Switch 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 Gigabit Ethernet 1 to destination port Gigabit Ethernet 2:
Switch(config)# monitor session 1 source interface gigabitethernet1/0/1 both
Switch(config)# monitor session 1 destination interface gigabitethernet1/0/2
This example shows how to delete a destination port from an existing local SPAN session:
Switch(config)# no monitor session 2 destination gigabitethernet1/0/2
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 fastethernet1/0/10 , fastethernet1/0/12
Switch(config)# monitor session 1 source interface fastethernet1/0/2 rx
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 fastethernet1/0/10
This example shows how to configure the destination port for ingress traffic on VLAN 5 by using a
security device that supports 802.1Q encapsulation. Egress traffic replicates the source; ingress traffic
uses 802.1Q encapsulation.
Switch(config)# monitor session 2 destination interface fastethernet1/0/5 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 fastethernet1/0/5 ingress untagged
vlan 5
You can verify your settings by entering the show monitor privileged EXEC command. You can view
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.
