802.1ab Link Layer Discovery Protocol

802.1ab Link Layer Discovery Protocol (LLDP) is a standard for discovering the physical

topology between neighboring devices. 802.1ab LLDP defines a standard method for Ethernet

network devices, such as switches, routers, and IP Deskphones to advertise information about

themselves to other nodes on the network and to store the information they discover in a

Management Information Base (MIB).

802.1ab (LLDP) takes advantage of the VLAN Name and Network Policy TLVs, and provides

an automatic configuration of the IP Deskphone network policy parameters. Key parameters,

such as VLAN ID, L2 priority, and DSCP values are received from the switch and are

automatically configured in the IP Deskphone.

802.1ab Link Layer Discovery Protocol (LLDP) provides the following functionality

• Periodic transmission of advertisements containing device information, device

capabilities and media specific configuration information to neighbors attached to the

same network.

• Reception of LLDP advertisements from its neighbors.

• Implementation of behavioral requirements specified by Link Layer Discovery Protocol

Media Endpoint Discovery (LLDP-MED).

• Storage of received data in local data structures, for example, in MIB modules.

TLVs

The information fields in each MIB are contained in a Link Layer Discovery Protocol Data Unit

(LLDPDU) as a sequence of short, variable-length, information elements known as TLVs that

each include type, length, and value fields. Each LLDPDU includes several mandatory TLVs

plus optional TLVs. Optional TLVs may be inserted in any order.

The IP Deskphone supports both the transmit and receive LLDP mode.

Transmit direction:

An LLDPDU transmitted by the IP Deskphone supports the following TLVs:
