Configuring DCBX 5

2. Apply the current FCoE profile map to the interface using the fcoeport command.

switch(conf-if-te-0/0)# fcoeport

3. Return to the privileged EXEC mode using the end command.

switch(conf-if-te-0/0)#end

4. Confirm the changes to the interface with the show running-configcommand.

switch#show running-config interface tengigabitethernet 0/0 interface TenGigabitEthernet 0/0

fcoeport shutdown

5. Use the show fcoe-mapcommand to confirm the current status of the FCoE map.

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

switch# show fcoe-map

fcoe-map default	: default
cee-map
fcoe-vlan	:	5
interface(s) :		te0/0

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:

•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.

To configure the TLVs for DCBX, perform the following steps in global configuration mode. 1. Set the protocol type to LLDP.

switch(config)#protocol lldp

2. Activate the protocol.

switch(conf-lldp)#no disable

3. Activate the TLV formats using the advertise command in LLDP configuration mode.

switch(conf-lldp)#advertise dcbx-fcoe-app-tlv switch(conf-lldp)#advertise dcbx-fcoe-logical-link-tlv

4. Enter the copy command to save the running-configfile to the startup-configfile.

switch(conf-lldp)#do copy running-config startup-config
