Figure 82. Extended Power via MDI TLVConfigure LLDPConfiguring LLDP is a two-step process.1. Enable LLDP globally.2. Advertise TLVs out of an interface.Related Configuration Tasks• Viewing the LLDP Configuration• Viewing Information Advertised by Adjacent LLDP Agents• Configuring LLDPDU Intervals• Configuring Transmit and Receive Mode• Configuring a Time to Live• Debugging LLDPImportant 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 eightexceeds 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 the CONFIGURATION mode andINTERFACE 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 levelconfigurations.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 configurationLink Layer Discovery Protocol (LLDP) 503
