VLAN and revert it to a normal MAC learning VLAN.

Default Configuration
There is no default configuration for this command.
Command Modes
VLAN Configuration mode.
User Guidelines
Remote-span VLANs must be configured as a tagged VLAN on trunk or
general mode ports on RSPAN transit switches. Traffic in an RSPAN VLAN is
always flooded as MAC address learning and link local protocols are disabled
on RSPAN VLANs. VLANs on transit switches must be configured as remote-
span VLANs in order to ensure delivery of all mirrored packets. Remote-span
VLANs configured on transit switches may co-exist with other non remote-
span VLANs on trunk ports. Do not configure the RSPAN VLAN as a member
of spanning tree (RSTP-PV or MST).
Example
console#vlan 10
console(config-vlan10)#remote-span
