Displaying Vlan-Vpn Configuration; Vlan-Vpn Configuration Example; Transmitting User Packets Through A Tunnel In The Public Network By Using Vlan-Vpn - H3C S5100-SI Operation Manual

Operation
Set the TPID value globally
Enter Ethernet port view
Set the port to be a VLAN-VPN
uplink port
A port cannot be configured as both a VLAN VPN port and a VLAN VPN uplink port at the same
time.
With the TPID being 0x8100, every port can be configured as a VLAN VPN uplink port. However, if
the TPID value is not the default value, you need to use the vlan-vpn uplink enable command to
specify a VLAN VPN uplink port.
A VLAN VPN uplink port does not remove the outer VLAN tags of packets to be sent through it, so
a VLAN VPN uplink port must be configured as a trunk port or hybrid port and configured to keep
the outer VLAN when sending packets of the outer VLAN.

Displaying VLAN-VPN Configuration

After the configuration above, you can execute the display command in any view to view the running
status of VLAN-VPN and verify the configuration.
