Chapter24 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. T he 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 int erfac e, an d to e nab le ingr es s f orward ing
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
Specifying VLANs to Filter
Beginning in privileged EXEC mode, follow these steps to configure the RSPAN source session to limit
RSPAN source traffic to specific VLANs:
Step5 end Return to privileged EXEC mode.
Step6 show monitor [session session_number]
show running-config
Verify the configuration.
Step7 copy running-config startup-config (Optional) Save the configuration in the configuration file.
Command Purpose
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 no monitor session {session_number | all |
local | remote}Remove any existing SPAN configuration for the session.
For session_number, the range is 1 to 66.
Specify all to remove all SPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
Step3 monitor session session_number source
interface interface-id Specify the characteristics of the source port (monitored port) and
SPAN session.
For session_number, the range is 1 to 66.
For interface-id, specify the source port to monitor. The interface
specified must already be configured as a trunk port.
Step4 monitor session session_number filter vlan
vlan-id [, | -]Limit the SPAN source traffic to specific VLANs.
For session_number, enter the session number specified in step 3.
For vlan-id, the range is 1 to 4094.
(Optional) Use a comma (,) to specify a series of VLANs or use a
hyphen (-) to specify a range of VLANs. Enter a space before and after
the comma; enter a space before and after the hyphen .
