Configuration Notes

Configuration Notes

This section describes the notes about configuring Layer 2 protocol transparent transmission.

Network Element Involved


License Support

Layer 2 Protocol Transparent Transmission is a basic feature of a router and is not under license control.

Feature Dependency and Limitation

  • When configuring Layer 2 protocol transparent transmission, do not use multicast MAC addresses that have been used on the device.
  • The user-side interface cannot be a VLANIF interface; otherwise, protocol packets cannot be transmitted.
  • Currently, the device supports transparent transmission of packets of the following Layer 2 protocols:

    • Spanning Tree Protocol (STP)
    • Link Aggregation Control Protocol (LACP)
    • Link Layer Discovery Protocol (LLDP)
    • Cisco Discovery Protocol (CDP)
    • User-defined protocols
