Chapter 28 Configuring LLDP and LLDP-MED

Configuring LLDP and LLDP-MED

Configuring LLDP-MED TLVs

By default, the switch only sends LLDP packets until it receives LLDP-MED packets from the end device. The device continues to send LLDP-MED packets until it receives LLDP packets only.

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