Follow these steps to create a new
VLAN, then configure it to be the RSPAN VLAN for the RSPAN session.
You must create the RSPAN VLAN in all
devices that will participate in RSPAN. If the
RSPAN VLAN-ID is in the normal range (lower than 1005) and VTP is enabled in
the network, you can create the RSPAN VLAN in one
device, and VTP propagates it to the other
devices in the VTP domain. For extended-range
VLANs (greater than 1005), you must configure RSPAN VLAN on both source and
destination
devices and any intermediate
devices.
Use VTP pruning to get an efficient flow of RSPAN traffic, or
manually delete the RSPAN VLAN from all trunks that do not need to carry the
RSPAN traffic.
To remove the remote SPAN characteristic from a VLAN and convert
it back to a normal VLAN, use the
no remote-span VLAN 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 .
