Configuring VLAN Interfaces

rspan
- Keyword to create a VLAN used for mirroring traffic from
remote switches. The VLAN used for RSPAN cannot include VLAN 1 (the
switch’s default VLAN). Nor should it include VLAN 4093 (which is used
for switch clustering). Configuring VLAN 4093 for other purposes may
cause problems in the Clustering operation. For more information on
configuring RSPAN through the CLI, see “RSPAN Mirroring Commands”
on page 405.
