Chapter 30 Configuring LLDP, LLDP-MED, and Wired Location Service
Command
Step 3

Step 4
lldp timer rate
Step 5 lldp tlv-select
Step 6

Step 9 copy running-config startup-config
Use the no form of each of the LLDP commands to return to the default setting.
This example shows how to configure LLDP characteristics.
Switch# configure terminal
Switch(config)# lldp holdtime 120
Switch(config)# lldp reinit 2
Switch(config)# lldp timer 30
Switch(config)# end
Configuring LLDP-MED TLVs
By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end
device. It then sends LLDP packets with MED TLVs, as well. When the LLDP-MED entry has been aged
out, it again only sends LLDP packets.
By using the lldp interface configuration command, you can configure the interface not to send the TLVs
listed in
Table 30-2
LLDP-MED TLV
inventory-management
location
network-policy
power-management
Beginning in privileged EXEC mode, follow these steps to enable a TLV on an interface:
Command
Step 1
configure terminal
Step 2 interface interface-id
OL-21521-01
Purpose
(Optional) Specify the delay time in seconds for LLDP to initialize on an
interface.
The range is 2 to 5 seconds; the default is 2 seconds.
(Optional) Set the sending frequency of LLDP updates in seconds.
The range is 5 to 65534 seconds; the default is 30 seconds.
(Optional) Specify the LLDP TLVs to send or receive.
(Optional) Specify the LLDP-MED TLVs to send or receive.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the configuration file.
Table 30-2.
