Chapter 66 Configuring SPAN and RSPAN
Configuring RSPAN
This example shows how to configure VLAN 901 as the source remote VLAN and how to configure the
destination port for ingress traffic on VLAN 5 by using a security device that supports 802.1Q
encapsulation:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface gigabitEthernet1/2 ingress vlan 5
Switch(config)# end
Removing Ports from an RSPAN Session
To remove a port as an RSPAN source for a session, perform this task:
Step 3
Switch(config)# [monitor session
session_number destination interface
interface-id [encapsulation {dot1q
[ingress vlan vlan id]} | ingress vlan
vlan id] [learning]]
Specifies the RSPAN session, the destination port, the packet
encapsulation, and the ingress VLAN.
For session_number, specifies the session number identified with this
RSPAN session (1 through 6).
For interface-id, specifies the destination port. Valid interfaces
include physical interfaces.
(Optional) Specifies the encapsulation of the packets transmitted on
the RSPAN destination port. If no encapsulation is specified, all
transmitted packets are sent in native format (untagged).
• Enter encapsulation dot1q to send native VLAN packets
untagged, and all other VLAN tx packets tagged dot1q.
(Optional) Specifies whether forwarding is enabled for ingress traffic
on the RSPAN destination port.
• For native (untagged) and dot1q encapsulation, specify ingress
vlan vlan id to enable ingress forwarding with vlan id as the
native VLAN; vlan id is also used as the native VLAN for
transmitted packets.
• Specify learning to enable learning when ingress is enabled.
Step 4
Switch(config)# end
Returns to privileged EXEC mode.
Step 5
Switch# show monitor [session
session_number]
Verifies your entries.
Step 6
Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
