Enabling QinQ-based Layer 2 Transparent Transmission on an Interface
Context
Perform the following operations on PEs based on the required Layer 2 protocol transparent transmission mode.
The l2protocol-tunnel vlan and l2protocol-tunnel commands cannot specify the same protocol type on the same interface. Otherwise, the configurations conflict.
Procedure
- Run:
system-view
The system view is displayed.
- Run:
interface interface-type interface-number
The user-side interface view is displayed.
- Run:
port link-type hybrid
The link type of the interface is set to hybrid.
- Run:
port hybrid untagged vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }
The interface is added to specified VLANs in untagged mode.
- Run:
port vlan-stacking vlan vlan-id1 [ to vlan-id2 ] stack-vlan vlan-id3
The interface is configured to add an outer VLAN tag to Layer 2 protocol packets.
- Run:
l2protocol-tunnel { all | protocol-type | user-defined-protocol protocol-name } vlan { low-id [ to high-id ] } &<1-10>
QinQ-based Layer 2 protocol transparent transmission is enabled on the interface.
The outer VLAN tag (vlan-id3) specified in the port vlan-stacking command must be included in the VLAN range specified in the port hybrid untagged vlan command.
