Command
Step 4 monitor session session_number
destination {interface interface-id [, | -]
[ingress {dot1q vlan vlan-id | isl | untagged
vlan vlan-id | vlan vlan-id}]}
Step 5 end
Step 6 show monitor [session session_number]
show running-config
Step 7
copy running-config startup-config
To delete an RSPAN session, use the no monitor session session_number global configuration
command. To remove a destination port from the RSPAN session, use the no monitor session
session_number destination interface interface-id global configuration command. The ingress options
are ignored with the no form of the command.
This example shows how to configure VLAN 901 as the source remote VLAN in RSPAN session 2, to
configure Gigabit Ethernet source port 2 as the destination interface, and to enable forwarding of
incoming traffic on the interface with VLAN 6 as the default receiving VLAN.
Switch(config)# monitor session 2 source remote vlan 901
Switch(config)# monitor session 2 destination interface gigabitethernet0/2 ingress vlan 6
Switch(config)# end
OL-8915-01
Purpose
Specify the SPAN session, the destination port, the packet
encapsulation, and the incoming VLAN and encapsulation.
For session_number, enter the number defined in Step 4.
In an RSPAN destination session, you must use the same session
number for the source RSPAN VLAN and the destination port.
For interface-id, specify the destination interface. The destination
interface must be a physical interface.
Though visible in the command-line help string, encapsulation
replicate is not supported for RSPAN. The original VLAN ID is
overwritten by the RSPAN VLAN ID, and all packets appear on the
destination port as untagged.
(Optional) [, | -] Specify a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the
hyphen.
Enter ingress with additional keywords to enable forwarding of
incoming traffic on the destination port and to specify the
encapsulation type:
dot1q vlan vlan-id—Forward incoming packets with IEEE
•
802.1Q encapsulation with the specified VLAN as the default
VLAN.
isl—Forward ingress packets with ISL encapsulation.
•
untagged vlan vlan-id or vlan vlan-id—Forward incoming
•
packets with untagged encapsulation type with the specified
VLAN as the default VLAN.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
