Configuring SPAN and RSPAN
Command
Step 4
monitor session session_number
destination {interface interface-id [, | -]
[ingress {dot1q vlan vlan-id | 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 ingress forwarding
on the interface with VLAN 6 as the default incoming 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

Purpose
Specify the SPAN session, the destination port, the packet
encapsulation, and the ingress VLAN and encapsulation.
For session_number, enter the number defined in Step 4.
Note 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.
Note 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 ingress traffic
forwarding 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.
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.
