Configuring LLDP Characteristics
You can configure the frequency of LLDP updates, the amount of time to hold the information before
discarding it, and the initialization delay time. You can also select the LLDP and LLDP-MED TLVs to
send and receive.
Beginning in privileged EXEC mode, follow these steps to configure the LLDP characteristics.
Note Steps 2 through 5 are optional and can be performed in any order.
Use the no form of each of the LLDP commands to return to the default setting.
This example shows how to configure LLDP characteristics.
