Chapter 11 Configuring SPAN and RSPAN
Configuring SPAN and RSPAN
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.
EXAMPLE
This example shows how to configure VLAN 901 as the source remote VLAN in RSPAN session 2,
configure Gigabit Ethernet source port 2 as the destination interface, and 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
Step 4
monitor session session_number
destination {interface interface-id [,
| -] [ingress {dot1q vlan vlan-id |
untagged vlan vlan-id | vlan
vlan-id}]}
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
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.
Step 5
end Return to privileged EXEC mode.
Step 6
show monitor [session
session_number]
show running-config
Verify the configuration.
Step 7
copy running-config startup-config (Optional) Save the configuration in the configuration file.
