Data Center Bridging (DCB)

Data center bridging (DCB) refers to a set of IEEE Ethernet enhancements that provide data centers with a single, robust,

converged network to support multiple trac types, including local area network (LAN), server, and storage trac. DCB features are

auto-congured in standalone mode.

The Dell Networking OS commands for DCB features include 802.1Qbb priority-based ow control (PFC), 802.1Qaz enhanced

transmission selection (ETS), and the data center bridging exchange (DCBX) protocol.

CLI commands for individual DCB features are as follows:

DCB command

• dcb enable auto-detect on-next-reload

• show qos dcb-map

PFC Commands

• clear pfc counters

• show interface pfc

• show interface pfc statistics

ETS Commands

• clear ets counters

• show interface ets

DCBX Commands

• dcbx version

• clear dcbx counters

• show dcb

• show interface dcbx detail

advertise dcbx-appln-tlv

On a DCBX port with a manual role, congure the application priority TLVs advertised on the interface to DCBX peers.

Syntax

advertise dcbx-appln-tlv {fcoe | iscsi}

To remove the application priority TLVs, use the no advertise dcbx-appln-tlv {fcoe |

iscsi} command.

Parameters

{fcoe | iscsi} Enter the application priority TLVs, where:

• fcoe: enables the advertisement of FCoE in application priority TLVs.
