LLDP and LLDP-MED are used primarily in conjunction with network management tools to provide information about network topology and configuration, and to help troubleshoot problems that occur on the network. The discovery protocols can also facilitate inventory management within a company. LLDP and the LLDP-MED extension are vendor-neutral discovery protocols that can discover devices made by numerous vendors. LLDP-MED is intended to be used on ports that connect to VoIP phones. Additional applications for LLDP-MED include device location (including for Emergency Call Service/E911) and Power over Ethernet management. 3.13.1. LLDP and Data Center Application DCBX uses TLV information elements over LLDP to exchange information, so LLDP must be enabled on the port to enable the information exchange. 3.13.2. Configuring LLDP This example shows how to configure LLDP settings for the switch and to allow port 0/3 to transmit all LLDP information available. To configure the switch: 1. Configure the transmission interval, hold multiplier, and reinitialization delay for LLDP PDUs sent from the switch. (Switch) #configure (Switch) (Config)#lldp timers interval 60 hold 5 reinit 3 2. Enable port 0/3 to transmit and receive LLDP PDUs. (Switch) (Config)#interface 0/3 (Switch) (Interface 0/3)#lldp transmit (Switch) (Interface 0/3)#lldp receive 3. Enable port 0/3 to transmit management address information in the LLDP PDUs and to send topology change notifications if a device is added or removed from the port. (Switch) (Interface 0/3)#lldp transmit-mgmt (Switch) (Interface 0/3)#lldp notification 4. Specify the TLV information to be included in the LLDP PDUs transmitted from port 0/3. (Switch) (Interface 0/3)#lldp transmit-tlv sys-name sys-desc sys-cap port-desc 5. Set the port description to be transmitted in LLDP PDUs. (Switch) (Interface 0/3)#description "Test Lab Port" 6. Exit to Privileged EXEC mode. (Switch) (Interface 0/3)# 7. View global LLDP settings on the switch. NETGEAR M4500 Series Switches Software Administration Manual 99
