DRAFT: BROCADE CONFIDENTIAL
To advertise the optional LLDP TLVs, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter LLDP configuration mode.
switch(config)#protocol lldp
3. Advertise the optional LLDP TLVs.
switch(conf-lldp)#advertise optional-tlv management-address port-description

Configuring the advertisement of LLDP DCBX-related TLVs
NOTE
By default, the dcbx-tlv is advertised; the dot1-tlv, dot3-tlv, dcbx-fcoe-app-tlv, and
dcbx-fcoe-logical-link-tlv are not advertised.
To configure the LLDP DCBX-related TLVs to be advertised, perform the following steps from
privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter LLDP configuration mode.
switch(config)#protocol lldp
3. Advertise the LLDP DCBX-related TLVs using these commands:
•switch(conf-lldp)#advertise dcbx-fcoe-app-tlv
•switch(conf-lldp)#advertise dcbx-fcoe-logical-link-tlv
•switch(conf-lldp)#advertise dcbx-tlv
•switch(conf-lldp)#advertise dot1-tlv
•switch(conf-lldp)#advertise dot3-tlv
Configuring FCoE priority bits
The FCoE priority bit setting is a bitmap setting where each bit position stands for a priority. When
you set a bit for a particular priority, that priority setting is applied to the FCoE traffic (that is, the
incoming FCoE traffic will have that priority). The default value is 0.
NOTE
FCoE traffic is only supported on the priority level that also has flow control enabled. This means that
the final advertised FCoE priority consists of the configured FCoE priority setting and the per-priority
flow control setting.
Even though setting multiple bits is allowed (exercising the full range of values), it doesn't make
sense to set more than one bit, because adapters don't support multiple priorities for FCoE.
To configure the FCoE priority bits, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter LLDP configuration mode.
switch(config)#protocol lldp
3. Configure the FCoE priority bits.
switch(conf-lldp)#lldp fcoe-priority-bits 3
