Configuring Dcbx - Brocade Communications Systems Converged Enhanced Ethernet 8000 Administrator's Manual

2. Apply the current FCoE profile map to the interface using the fcoeport command.
3. Return to the privileged EXEC mode using the end command.
4. Confirm the changes to the interface with the show running-config command.
5. Use the show fcoe-map command to confirm the current status of the FCoE map.
6. Repeat this procedure for any additional interfaces.

Configuring DCBX

Data Center Bridging eXchange Protocol (DCBX) runs on CEE links and is an extension of the Link
Layer Discovery Protocol (LLDP). The primary goal of DCBX is to allow the discovery of CEE-capable
hosts and switches and allow CEE-specific parameters—such as those for Enhanced Transmission
Selection (ETS) and Priority Flow Control (PFC)—to be sent before the link is shared. DCBX
parameters use a type-length-value (TLV) format. By default, DCBX is turned on and the two TLVs
are enabled. The available TLVS are:
•
•
To configure the TLVs for DCBX, perform the following steps in global configuration mode.
1. Set the protocol type to LLDP.
2. Activate the protocol.
3. Activate the TLV formats using the advertise command in LLDP configuration mode.
4. Enter the copy command to save the running-config file to the startup-config file.

The following example shows that the FCoE VLAN has been assigned the ID of 5, and the map
has been assigned to the interface.

dcbx-fcoe-app-tlv—IEEE Data Center Bridging eXchange FCoE Application TLV.
dcbx-fcoe-logical-link-tlv—IEEE Data Center Bridging eXchange FCoE Logical Link TLV. The
presence of this TLV declares that the FCoE part of the converged link is UP.
