• 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 ofinterfaces 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.LLDP Compatibility• Spanning tree and force10 ring protocol “blocked” ports allow LLDPDUs.• 802.1X controlled ports do not allow LLDPDUs until the connected device is authenticated.CONFIGURATION versus INTERFACE ConfigurationsAll LLDP configuration commands are available in PROTOCOL LLDP mode, which is a sub-mode of theCONFIGURATION mode and INTERFACE mode.• Configurations made at the CONFIGURATION level are global; that is, they affect all interfaces on thesystem.• Configurations made at the INTERFACE level affect only the specific interface; they overrideCONFIGURATION level configurations.Example of the protocol lldp Command (CONFIGURATION Level)R1(conf)#protocol lldpR1(conf-lldp)#?advertise Advertise TLVsdisable Disable LLDP protocol globallyend Exit from configuration modeexit Exit from LLDP configuration modehello LLDP hello configurationmode LLDP mode configuration (default = rx and tx)multiplier LLDP multiplier configurationno Negate a command or set its defaultsshow Show LLDP configurationDell(conf-lldp)#exitDell(conf)#interface tengigabitethernet 1/3/1Dell(conf-if-te-1/3/1)#protocol lldpDell(conf-if-te-1/3/1-lldp)#?advertise Advertise TLVsdisable Disable LLDP protocol on this interfaceend Exit from configuration modeexit Exit from LLDP configuration modehello LLDP hello configurationmode LLDP mode configuration (default = rx and tx)multiplier LLDP multiplier configurationno Negate a command or set its defaultsshow Show LLDP configurationDell(conf-if-te-1/3/1-lldp)#Link Layer Discovery Protocol (LLDP) 535
