Huawei Technologies Proprietary
1-6
Caution:
z You can execute the vlan-vpn enable or vlan-vpn uplink enable command for a
port, but do not execute both of the two commands for a port.
z When the TPID is set to the default value 0x8100, a port can serve as an uplink port
no matter whether the vlan-vpn uplink enable command is configured on this port
or not. However, if the TPID is not set to 0x8100, you must enable the vlan-vpn
uplink enable command on the port if you want to make the port an uplink port.
