Description
Use the vlan-vpn enable command to enable the VLAN-VPN function for a port.
Use the undo vlan-vpn command to disable the VLAN-VPN function for a port.
By default, the VLAN-VPN function is disabled for port.
With the VLAN VPN function enabled, a received packet is tagged with the default
VLAN tag of the receiving port no matter whether or not the packet already carries a
VLAN tag. If the packet already carries a VLAN tag, the packet becomes a dual-tagged
packet. Otherwise, the packet becomes a packet carrying the default VLAN tag of the
port.
Caution:
The VLAN-VPN function is unavailable if the port has any of the protocols among
GVRP, GMRP, STP, IRF, NTDP and 802.1x enabled.
After you enable the VLAN-VPN function for a port, you cannot change the attribute
of the port to trunk or hybrid, or enable GVRP, GMRP, IRF, NTDP, or STP function
for the port.
If there is a port enabled with fabric function on a device, you cannot enable
VLAN-VPN function for this port or for any other port on this device.
