Configuring LLDP and LLDP-MED

Beginning in privileged EXEC mode, follow these steps to enable LLDP on an interface when it has been

disabled:

This example shows how to enable LLDP on an interface.

Switch# configure terminal

Switch(config)# interface GigabitEthernet1/0/1

Switch(config-if)# no shutdown

Switch(config-if)# port-type nni

Switch(config-if)# lldp transmit

Switch(config-if)# lldp receive

Switch(config-if)# end

Configuring LLDP-MED TLVs

By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end

device. It will then send LLDP packets with MED TLVs as well. When the LLDP-MED entry has been

aged out, it only sends LLDP packets again.

Using the lldp interface configuration command, you can configure the interface not to send the TLVs

listed in Table 24-2.

Step 3 no lldp transmit No LLDP packets are sent on the interface.

Step 4 no lldp receive No LLDP packets are received on the interface.

Step 5 end Return to privileged EXEC mode.

Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.

Command Purpose

Step 1 configure terminal Enter global configuration mode.

Step 2 interface interface-id Specify the interface on which you are enabling LLDP, and enter

interface configuration mode. LLDP is supported only on NNIs and

ENIs. It is not supported on UNIs. If necessary, use the port-type

{eni | nni} interface configuration command to change the port type.

Step 3 no shutdown If necessary, enable the port. By default NNIs are enabled, and ENIs

and UNIs are disabled.

Step 4 lldp transmit LLDP packets are sent on the interface.

Step 5 lldp receive LLDP packets are received on the interface.

Step 6 end Return to privileged EXEC mode.

Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file.
