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 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.

R1(conf)#protocol lldp
R1(conf-lldp)#?
