Configuration Guide - Ethernet Switching

CloudEngine 8800, 7800, 6800, and 5800 V200R003C00

This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, VLANs, MUX VLAN, Voice VLAN, VLAN mapping, QinQ, GVRP, VCMP, STP/RSTP/MSTP, VBST, SEP, RRPP, ERPS, LBDT, and Layer 2 protocol transparent transmission.

Enabling Layer 2 Protocol Transparent Transmission on an Interface

Enabling Layer 2 Protocol Transparent Transmission on an Interface


Perform the following operations on PEs based on the required Layer 2 protocol transparent transmission mode.


The l2protocol-tunnel and l2protocol-tunnel vlan commands cannot specify the same protocol type on the same interface. Otherwise, the configurations conflict.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The user-side interface view is displayed.

  3. Run port link-type hybrid

    The link type of the interface is set to hybrid.

  4. Run port hybrid pvid vlan vlan-id

    The default VLAN of the interface is configured.

  5. Run port hybrid untagged vlan vlan-id

    The interface is added to the default VLAN in untagged mode.


    The VLAN tag specified in step 5 must be the same as that specified in step 4.

  6. Run l2protocol-tunnel { all | protocol-type | user-defined-protocol protocol-name } enable

    Layer 2 protocol transparent transmission is enabled on the interface.

  7. (Optional) Run l2protocol-tunnel drop-threshold

    The drop threshold for Layer 2 protocol packets is configured.

    By default, the drop threshold is 0, meaning that interfaces enabled with Layer 2 protocol tunneling do not limit the volume of received Layer 2 protocol packets.

    Configuring a drop threshold for Layer 2 protocol packets protects interfaces enabled with Layer 2 protocol tunneling against protocol packet attacks. The interfaces drop excess Layer 2 protocol packets when the number of Layer 2 protocol packets received in 1s exceeds the configured drop threshold.

  8. Run commit

    The configuration is committed.
