Usage Guidelines
When a VLAN is converted from a normal VLAN to an RSPAN VLAN (or the reverse), the VLAN is
first deleted and is then recreated with the new configuration. The RSPAN feature is propagated by
VLAN Trunking Protocol (VTP) for VLAN-IDs that are lower than 1005.
Before you configure the RSPAN remote-span feature, use the vlan (global configuration) command to
create the VLAN.
Examples
