Configuring DCBX

Configuring DCBX

DCB allows DCB devices at both ends of a link to discover and exchange DCB configurations.

Pre-configuration Tasks

Before configuring DCBX, complete the following task:
  • Configuring a link layer protocol so that interfaces at both ends of a link are Up


  1. Run:


    The system view is displayed.

  2. Run:

    lldp enable

    The Link Layer Discovery Protocol (LLDP) is enabled globally.

  3. Run:

    interface interface-type interface-number

    The interface view is displayed.

  4. Run:

    lldp tlv-enable dcbx

    The interface is configured to advertise DCBX TLVs.

  5. (Optional) Run:

    dcb compliance intel-oui

    The version number in the outgoing DCBX TLV is set.

    Two standards are available for the Data Center Bridging eXchange (DCBX) protocol: IEEE DCBX and Intel DCBX.

    By default, an interface sends DCBX TLVs of the IEEE standard version.

  6. Run:


    The configuration is committed.

Checking the Configuration

Run the display lldp tlv-config [ interface interface-type interface-number ] command to check TLV types supported by the system or an interface.
