Enabling DCBX

Support for DCBX is automatically enabled when you enable LLDP. This procedure provides alternative manual steps in case certain automatic processes fail.

How to Enable the Data Center Bridging Exchange Feature Manually

Before You Begin

Ensure that you install LLDP. For more information about enabling LLDP, see Enabling LLDP on the System.

  1. Become an administrator.

    For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

  2. Verify that the LLDP service is running.
    $ svcs lldp

    If the LLDP service is disabled, start the service with the following command:

    $ svcadm enable svc:/network/lldp:default
  3. Ensure that the LLDP agent is running on Rx and Tx modes.
    $ lldpadm show-agentprop -p mode agent

    If the LLDP agent is not enabled on both modes, type the following command:

    $ lldpadm set-agentprop -p mode=both agent

    For the other possible configurations of the LLDP agents, see Enabling LLDP on the System.

  4. Verify that the underlying NIC supports DCB.
    $ dladm show-linkprop -p ntcs agent

    A property value that is greater than zero (0) indicates that the NIC supports DCB.
