RSPAN Mirroring Commands
– 466 –
Command Usage
◆ Only 802.1Q trunk or hybrid (i.e., general use) ports can be configured as an
RSPAN uplink port – access ports are not allowed (see switchport mode).
◆ Only one uplink port can be configured on a source switch, but there is no
limitation on the number of uplink ports configured on an intermediate or
destination switch.
◆ 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)
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)#no rspan session 1
Console(config)#
