Important Points to Remember
● LLDP is enabled by default.
● Dell Networking systems support up to eight neighbors per interface.
● Dell Networking systems support a maximum of 8000 total neighbors per system. If the number of interfaces multiplied by
eight exceeds the maximum, the system does not configure more than 8000.
● INTERFACE level configurations override all CONFIGURATION level configurations.
● LLDP is not hitless.
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
mode LLDP mode configuration (default = rx and tx)
multiplier LLDP multiplier configuration
no Negate a command or set its defaults
show Show LLDP configuration
Dell(conf-lldp)#exit
Dell(conf)#interface tengigabitethernet 0/3
Dell(conf-if-te-0/3)#protocol lldp
Dell(conf-if-te-0/3-lldp)#?
advertise Advertise TLVs
disable Disable LLDP protocol on this interface
end Exit from configuration mode
exit Exit from LLDP configuration mode
hello LLDP hello configuration
mode LLDP mode configuration (default = rx and tx)
multiplier LLDP multiplier configuration
no Negate a command or set its defaults
show Show LLDP configuration
Dell(conf-if-te-0/3-lldp)#
Enabling LLDP
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.
