Reference Guide

• 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 conguration 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.

5 Enable DCBX on all switch ports in CONFIGURATION mode to activate the exchange of DCBX TLV messages with PFC, ETS, and
iSCSI congurations.
