Quidway S8500 Series Routing Switches
Parameter
None
Description
Use the vlan-vpn uplink enable command to set a port to be a VLAN-VPN uplink port.
Use the undo vlan-vpn uplink command to remove the configuration.
When sending a packet, a VLAN-VPN uplink port replaces the TPID value in the outer
VLAN tag with the configured TPID value. You can use the vlan-vpn tpid command to
set the TPID value used by the VLAN-VPN uplink port.
Caution:
At present, LSBM1XP4 and LSBM1TGX1 cards do not support this command.
The vlan-vpn uplink enable command and the vlan-vpn enable command are
mutually exclusive. That is, if you execute the vlan-vpn enable command on a port,
you will fail to execute the vlan-vpn uplink enable command on the same port; if
you execute the vlan-vpn uplink enable command on a port, you will fail to execute
the vlan-vpn enable command on the same port either.
Example
# Set Ethernet3/1/1 port to be a VLAN-VPN uplink port.
[Quidway-Ethernet3/1/1] vlan-vpn uplink enable
# Restore Ethernet3/1/1 port to a common port.
[Quidway-Ethernet3/1/1] undo vlan-vpn uplink
VLAN-VPN uplink status: enabled
