31 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). LLPD Commands The following are LLDP commands. advertise dot1-tlv Advertise dot1 TLVs (Type, Length, Value). C9000 Series Syntax advertise dot1-tlv {port-protocol-vlan-id | port-vlan-id | vlan-name} To remove advertised dot1-tlv, use the no advertise dot1-tlv {portprotocol-vlan-id | port-vlan-id | vlan-name} command. Parameters port-protocolvlan-id port-vlan-id Enter the keywords port-protocol-vlan-id to advertise the port protocol VLAN identification TLV. Enter the keywords port-vlan-id to advertise the port VLAN identification TLV. Link Layer Discovery Protocol (LLDP) 1269
