RSPAN Mirroring Commands
– 416 –
â—† Only destination and uplink ports will be assigned by the switch as members of
this VLAN. Ports cannot be manually assigned to an RSPAN VLAN with the
switchport allowed vlan command. Nor can GVRP dynamically add port
members to an RSPAN VLAN. Also, note that the show vlan command will not
display any members for an RSPAN VLAN, but will only show configured RSPAN
VLAN identifiers.
Example
The following example enables RSPAN on VLAN 2, specifies this device as an RSPAN
destination switch, and the uplink interface as port 3:
Console(config)#rspan session 1 remote vlan 2 destination uplink ethernet 1/3
Console(config)#
no rspan session Use this command to delete a configured RSPAN session.
Syntax
no rspan session session-id
session-id – A number identifying this RSPAN session. (Range: 1-2)
Only two mirror sessions are allowed, including both local and remote
mirroring. If local mirroring is enabled with the port monitor command,
then there is only one session available for RSPAN.
Command Mode
Global Configuration
Command Usage
The no rspan session command must be used to disable an RSPAN VLAN before it
can be deleted from the VLAN database (see the vlan command).
Example

Console(config)#

Syntax

session-id – A number identifying this RSPAN session. (Range: 1-2)
Only two mirror sessions are allowed, including both local and remote
mirroring. If local mirroring is enabled with the port monitor command,
then there is only one session available for RSPAN.
