Command

Step 10

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.
This example shows how to configure VLAN 901 as the source remote VLAN and port 1 as the
destination interface:
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface gigabitethernet0/1
Switch(config)# end
Creating an RSPAN Destination Session and Configuring Ingress Traffic
Beginning in privileged EXEC mode, follow these steps to create an RSPAN destination session, to
specify the source RSPAN VLAN and the destination port, and to enable ingress traffic on the destination
port for a network security device (such as a Cisco IDS Sensor Appliance).
For details about the keywords not related to ingress traffic, see the
Note
Session" section on page
Command
Step 1
configure terminal
Step 2
no monitor session {session_number | all
| local | remote}
Step 3
monitor session session_number source
remote vlan vlan-id
OL-9639-07
Purpose
Specify the RSPAN session and the destination interface.
For session_number, enter the number defined in Step 6.
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
26-18. This procedure assumes that the RSPAN VLAN has been configured.
Purpose
Enter global configuration mode.
Remove any existing SPAN configuration for the session.
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.
