vlan-vpn enable

Syntax
vlan-vpn enable
undo vlan-vpn
View
Ethernet port view/PVC view
Parameter
None
Description
Use the vlan-vpn enable command to enable VLAN VPN feature for the port or
the PVC.
Use the undo vlan-vpn command to disable VLAN VPN feature for the port or
the PVC.
With VLAN VPN enabled, a received packet is tagged with the default VLAN tag of
the port no matter whether or not the packet carries a VLAN tag. So, if the packet
already carries a VLAN tag, the default VLAN tag becomes a nested VLAN tag in
the packet. Otherwise, the packet is transmitted with the default VLAN tag
carried.
Make sure the VLAN identified by the nested-vlanid argument exists to prevent
otherwise the packets from being discarded due to no outbound port found.
The traffic-redirect modified-vlan command modifies the outer VLAN tag of
a packet.
At present, only 3C17514, 3C17516, and 3C17528 cards support the
traffic-redirect { nested-vlan | modified-vlan } command.
