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.
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.
