Usage
Information
Before LLDP can be configured on an interface, it must be enabled globally from CONFIGURATION mode.
This command places you in LLDP mode on the interface; it does not enable the protocol.
When you enter the LLDP protocol in the Interface context, it overrides global configurations. When you
execute the no protocol lldp from INTERFACE mode, interfaces begin to inherit the configuration
from global LLDP CONFIGURATION mode.
