Link Layer Discovery Protocol (LLDP)
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 system implementation of LLDP is based on IEEE standard
801.1ab.
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).
Topics:
• LLPD Commands
• snmp-notification-interval
• LLDP-MED Commands
LLPD Commands
The following are LLDP commands.
advertise dot1-tlv

To remove advertised dot1-tlv, use the no advertise dot1-tlv {port-protocol-vlan-id |
port-vlan-id | vlan-name} command.
Parameters
port-protocol-
vlan-id
Enter the keywords port-protocol-vlan-id to advertise the port protocol
VLAN identification TLV.
port-vlan-id Enter the keywords port-vlan-id to advertise the port VLAN identification
TLV.
vlan-name Enter the keywords vlan-name to advertise the vlan-name TLV. This keyword is
