Link Layer Discovery Protocol (LLDP)
Commands
The IEEE 802.1AB standard defines the Link Layer Discovery Protocol (LLDP). LLDP support is new
in SFTOS 2.5.1.
The commands in this chapter are:
• To clear LLDP information:
— clear lldp neighbors on page 159
— clear lldp counters on page 159
• To configure LLDP globally (on all ports):
— lldp mode (global) on page 160
• To configure LLDP on a single port:
— lldp mode (interface) on page 161 (timers not supported at interface
level)
— lldp notification on page 162
— lldp transmit-mgmt on page 163
— lldp transmit-tlv on page 163
• To change default timers (all global):
— lldp hello on page 160
— lldp multiplier on page 161
— lldp notification-interval on page 162
— lldp timers-reinit on page 163
• To display LLDP information:
— show lldp interface on page 164
— show lldp local-device on page 165
— show lldp neighbors on page 166
— show lldp remote-device on page 167
LLDP Overview
LLDP allows a switch residing on an 802.1Q VLAN to advertise connectivity, physical description,
management information, and major capabilities. The TLV (Type/Length/Value) information distributed
via this protocol is stored by its recipients in a standard Management Information Base (MIB),
facilitating multi-vendor interoperability and use of standard management tools to discover and make
available physical topology information for network management.
