CONFIGURATION versus INTERFACE
Configurations
All LLDP configuration commands are available in PROTOCOL LLDP mode, which is a sub-mode of the
CONFIGURATION mode and INTERFACE mode.
• Configurations made at the CONFIGURATION level are global; that is, they affect all interfaces on the
system.
• Configurations made at the INTERFACE level affect only the specific interface; they override
CONFIGURATION level configurations.
Example of the protocol lldp Command (CONFIGURATION Level)
Dell(conf)#protocol lldp
Dell(conf-lldp)#?
advertise Advertise TLVs
disable Disable LLDP protocol globally
end Exit from configuration mode
exit Exit from LLDP configuration mode
hello LLDP hello configuration

no Negate a command or set its defaults

LLDP is enabled by default. Enable and disable LLDP globally or per interface. If you enable LLDP globally, all
UP interfaces send periodic LLDPDUs.
To enable LLDP, use the following command.
