Usage
Information
LLDP must be enabled globally from CONFIGURATION mode, before it can be configured
on an interface. 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 the INTERFACE mode, interfaces
will begin to inherit the configuration from the global LLDP CONFIGURATION mode.
