Considerations When Using DCB

    Note the following considerations for using DCB:

  • DCB is only supported on Intel Niantic physical NICs.

    To verify whether the NIC supports DCB, issue the following command:

    # dladm show-linkprop -p ntcs agent

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

  • DCB ports that are configured in DCB mode cannot be aggregated (trunk or DLMP mode).

  • Because DCB supports only the IEEE version of DCBX (not the CEE or CIN versions), external bridges must support the IEEE version to interoperate with Oracle Solaris DCB.

  • DCB supports ETS configuration and recommendation TLVs.

  • DCB is only supported in the eight traffic class configuration.

  • DCB does not support congestion notification (CN).
