Command History
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 This example shows how to configure an RSPAN VLAN:
Switch(config)# vlan 901
Switch(config-vlan)# remote-span
This example shows how to remove the RSPAN feature from a VLAN:
Switch(config)# vlan 901
Switch(config-vlan)# no remote-span
You can verify your settings by entering the show vlan user EXEC command.
