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 software (FTOS) implementation of LLDP is
based on IEEE standard 801.1ab.
The FTOS supports the basic LLDP commands on Z9000 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).
Z9000
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.
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 only supported on the C-Series and S-Series.
