Link Layer Discovery Protocol (LLDP)
The link layer discovery protocol (LLDP) advertises connectivity and management from the local station
to the adjacent stations on an IEEE 802 LAN.
This chapter contains the following sections:
• LLPD Commands
• LLDP-MED Commands
LLDP facilitates multi-vendor interoperability by using standard management tools to discover and make
available a physical topology for network management. The Dell Networking operating software
implementation of LLDP is based on IEEE standard 801.1ab.
TheDell Networking OS supports the basic LLDP commands on S4820T platform.
The starting point for using LLDP is invoking LLDP with the protocol lldp command in either
CONFIGURATION or INTERFACE mode.
The information LLDP distributes is stored by its recipients in a standard management information base
(MIB). You can access the information by a network management system through a management
protocol such as simple network management protocol (SNMP).
LLPD Commands
The following are LLDP commands.
advertise dot1-tlv
Advertise dot1 TLVs (Type, Length, Value).
S4820T
Syntax
advertise dot1-tlv {port-protocol-vlan-id | port-vlan-id |
vlan-name}
To remove advertised dot1-tlv, use the no advertise dot1-tlv {port-
protocol-vlan-id | port-vlan-id | vlan-name} command.
