Configure DCBX

DCBX allows data center devices to advertise and exchange configuration settings with directly connected peers using LLDP. LLDP is enabled by default.

To ensure the consistent and efficient operation of a converged data center network, DCBX detects peer misconfiguration.

DCBX is disabled at a global level and enabled at an interface level by default. For DCBX to be operational, DCBX must be enabled at both the global and interface levels. You can manually reconfigure DCBX settings or disable DCBX on a per-interface basis.

  1. Configure the DCBX version used on a port in INTERFACE mode.
    dcbx version {auto | cee | ieee}
    • auto — Automatically selects the DCBX version based on the peer response (default).
    • cee — Sets the DCBX version to CEE.
    • ieee — Sets the DCBX version to IEEE 802.1Qaz.
  2. (Optional) A DCBX-enabled port advertises all TLVs by default. If PFC or ETS TLVs are disabled, enter the command in INTERFACE mode to re-enable PFC or ETS TLV advertisements.
    dcbx tlv-select {ets-conf | ets-reco | pfc}
    • ets-conf — Enables ETS configuration TLVs.
    • ets-reco — Enables ETS recommendation TLVs.
    • pfc — Enables PFC TLVs.
  3. (Optional) DCBX is enabled on a port by default. If DCBX is disabled, enable it in INTERFACE mode.
    lldp tlv-select dcbxp
  4. Return to CONFIGURATION mode.
    exit
  5. Enable DCBX on all switch ports in CONFIGURATION mode to activate the exchange of DCBX TLV messages with PFC, ETS, and iSCSI configurations.
    dcbx enable
