Chapter 11 Configuring SPAN and RSPAN
Configuring SPAN and RSPAN
To monitor all VLANs on the trunk port, use the no monitor session session_number filter global
configuration command.
EXAMPLE
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN
session 2 to monitor traffic received on Gigabit Ethernet trunk port 2, and send traffic for only VLANs
1 through 5 and VLAN 9 to destination Gigabit Ethernet port 1:
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet0/2 rx
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
Switch(config)# monitor session 2 destination interface gigabitethernet0/1
Switch(config)# end
Configuring RSPAN
• Configuring a VLAN as an RSPAN VLAN, page 11-18
• Creating an RSPAN Source Session, page 11-18
• Creating an RSPAN Destination Session, page 11-20
• Creating an RSPAN Destination Session and Configuring Ingress Traffic, page 11-22
• Specifying VLANs to Filter, page 11-24
Step 5
monitor session session_number
destination {interface interface-id [, |
-] [encapsulation {dot1q |
replicate}]}
Specify the SPAN session and the destination port
(monitoring port).
For session_number, specify the session number entered in
Step 3.
For interface-id, specify the destination port. The destination
interface must be a physical port; it cannot be an
EtherChannel, and it cannot be a VLAN.
(Optional) [, | -] Specify a series or range of interfaces. Enter
a space before and after the comma; enter a space before and
after the hyphen.
(Optional) Enter encapsulation dot1q or encapsulation
replicate to specify 802.1Q encapsulation or that the
destination interface replicates the source interface
encapsulation method. If not selected, the default is to send
packets in native form (untagged).
Step 6
end Return to privileged EXEC mode.
Step 7
show monitor [session
session_number]
show running-config
Verify the configuration.
Step 8
copy running-config startup-config (Optional) Save the configuration in the configuration file.
