Configuring SPAN and RSPAN
Creating an RSPAN Destination Session
You configure the RSPAN destination session on a different switch or switch stack; that is, not the switch
or switch stack on which the source session was configured.
Beginning in privileged EXEC mode, follow these steps to define the RSPAN VLAN on that switch, to
create an RSPAN destination session, and to specify the source RSPAN VLAN and the destination port:
Command
Step 1
configure terminal
Step 2
vlan vlan-id
Step 3
remote-span
Step 4
exit
Step 5
no monitor session {session_number | all |
local | remote}
Step 6
monitor session session_number source
remote vlan vlan-id
Step 7
monitor session session_number
destination interface interface-id
Step 8
end
Step 9
show monitor [session session_number]
show running-config
Step 10
copy running-config startup-config
To delete a SPAN session, use the no monitor session session_number global configuration command.
To remove a destination port from the SPAN session, use the no monitor session session_number
destination interface interface-id global configuration command. To remove the RSPAN VLAN from
the session, use the no monitor session session_number source remote vlan vlan-id.

Purpose
Enter global configuration mode.
Enter the VLAN ID of the RSPAN VLAN created from the source
switch, and enter VLAN configuration mode.
If both switches are participating in VTP and the RSPAN VLAN ID
is from 2 to 1005, Steps 2 through 4 are not required because the
RSPAN VLAN ID is propagated through the VTP network.
Identify the VLAN as the RSPAN VLAN.
Return to global configuration mode.
Remove any existing RSPAN configuration for the session.
For session_number, the range is 1 to 66.
Specify all to remove all RSPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
Specify the RSPAN session and the source RSPAN VLAN.
For session_number, the range is 1 to 66.
For vlan-id, specify the source RSPAN VLAN to monitor.
Specify the RSPAN session and the destination interface.
For session_number, enter the number defined in Step 6.
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
