LLDP is disabled by default.

•

Dell Force10 systems support up to 8 neighbors per interface. 

•

Dell Force10 systems support a maximum of 8000 total neighbors per system. If the number of 
interfaces multiplied by 8 exceeds the maximum, the system will not configure more than 8000.

•

INTERFACE level configurations override all CONFIGURATION level configurations.

•

LLDP is not hitless.

•

Spanning Tree and Force10 Ring Protocol “blocked” ports allow LLDPDUs.

•

802.1X controlled ports do not allow LLDPDUs until the connected device is authenticated.

All LLDP configuration commands are available in PROTOCOL LLDP mode, which is a sub-mode of 
CONFIGURATION mode and INTERFACE mode.

•

Configurations made at CONFIGURATION level are global, that is, they affect all interfaces on the 
system.

•

Configurations made at INTERFACE level affect only the specific interface, and they override 
CONFIGURATION level configurations.
