LLDP configuration and management 8 3. Advertise the optional LLDP TLVs. switch(conf-lldp)#advertise optional-tlv [port-description |system-name | system-capabilities | system-description | management-address] 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 0x08. 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. 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 Configuring LLDP profiles You can configure up to 64 profiles on a switch. Using the no profile NAME command deletes the entire profile. Dell Converged Enhanced Ethernet Administrator's Guide 83 53-1002116-01
