You can configure RSPAN VLANs only in config-VLAN mode (entered by using the vlan global

Before you configure the RSPAN remote-span command, use the vlan (global configuration) command

to create the VLAN.

The RSPAN VLAN has these characteristics:

RSPAN VLAN traffic flows only on trunk ports.

Spanning Tree Protocol (STP) can run in the RSPAN VLAN, but it does not run on RSPAN

destination ports.

When an existing VLAN is configured as an RSPAN VLAN, the VLAN is first deleted and then recreated

as an RSPAN VLAN. Any access ports are made inactive until the RSPAN feature is disabled.
