CONFIGURATION versus INTERFACE Congurations
All LLDP conguration commands are available in PROTOCOL LLDP mode, which is a sub-mode of the CONFIGURATION mode and
INTERFACE mode.
• Congurations made at the CONFIGURATION level are global; that is, they aect all interfaces on the system.
• Congurations made at the INTERFACE level aect only the specic interface; they override CONFIGURATION level
congurations.
