compatible settings. If you disable DCBX globally on a switch, you can re-enable it to ensure consistent operation
of peers in a converged data center network.
Example
OS10(config)# dcbx enable
Supported Releases 10.3.0E or later
dcbx tlv-select
Congures the DCB TLVs advertised by a DCBX-enabled port.
Syntax
dcbx tlv-select {[ets-conf] [ets-reco] [pfc]}
Parameters
• ets-conf — Advertise ETS conguration TLVs.
• ets-reco — Advertise ETS recommendation TLVs.
• pfc — Advertise PFC TLVs.
Default DCBX advertises PFC, ETS Recommendation, and ETS Conguration TLVs.
Command Mode INTERFACE
Usage Information A DCBX-enabled port advertises all TLVs to DCBX peers by default. If PFC or ETS TLVs are disabled, enter the
command to re-enable PFC or ETS TLV advertisements. You can enable multiple TLV options, such as ets-conf,
ets-reco, and pfc with the same command.
Example
OS10(conf-if-eth1/1/2)# dcbx tlv-select ets-conf pfc
Supported Releases 10.3.0E or later
dcbx version
Congures the DCBX version used on a port interface.
Syntax
dcbx version {auto | cee | ieee}
Parameters
• auto — Automatically select the DCBX version based on the peer response.
• cee — Set the DCBX version to CEE.
• ieee — Set the DCBX version to IEEE 802.1Qaz.
Default Auto
Command Mode INTERFACE
Usage Information In Auto mode, a DCBX-enabled port detects an incompatible DCBX version on a peer device port and automatically
recongures a compatible version on the local port. The no version of this command disables the DCBX version.
Example
OS10(conf-if-eth1/1/2)# dcbx version cee
