FTOS Configuration Guide for the C-Series - Force10 Networks

Important Points to Remember
• LLDP is disabled by default.
• The Force10 system suppports a maximum of 8000 neighbors.
• 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.
• FTOS processes CDP TLVs but does not transmit them. The following CDP TLVs are processed:
Device-ID, Address, Port-ID, Capabilities, Version, Platform, Native VLAN, and Full/Half Duplex.
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.
