Configuring SPAN and RSPAN
Command
Step 6
show monitor [session session_number]
show running-config
Step 7
copy running-config startup-config
To delete a SPAN session, use the no monitor session session_number global configuration command.
To remove a source port or VLAN from the SPAN session, use the no monitor session session_number
source {interface interface-id | vlan vlan-id} global configuration command. To remove the RSPAN
VLAN from the session, use the no monitor session session_number destination remote vlan vlan-id.
This example shows how to remove any existing RSPAN configuration for session 1, configure RSPAN
session 1 to monitor multiple source interfaces, and configure the destination as RSPAN VLAN 901.
Switch(config)# no monitor session 1
Switch(config)# monitor session 1 source interface gigabitethernet1/0/1 tx
Switch(config)# monitor session 1 source interface gigabitethernet1/0/2 rx
Switch(config)# monitor session 1 source interface port-channel 2
Switch(config)# monitor session 1 destination remote vlan 901
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:
Command
Step 1
configure terminal
Step 2
no monitor session {session_number | all |
local | remote}
Step 3

Specify all to remove all SPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
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.
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
