Dell S6000 FTOS 9.0(2.0) Configuration Guide for the System - Page 546

www.dell.com | support.dell.com Important Points to Remember • LLDP is disabled by default. • Dell Networking systems support up to 8 neighbors per interface. • Dell Networking 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. 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 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.
