Link Layer Discovery Protocol (LLDP) is a neutral link layer protocol for the provider that network devices use to advertise their identity, capabilities and neighbors in a local IEEE 802 based network, essentially wired Ethernet.
To support non-Cisco devices and allow interworking between other devices, the adapter supports the IEEE 802.1AB link layer discovery (LLDP) protocol. LLDPis is a neighbor discovery protocol that is used for network devices to advertise information to other devices on the network.
LLDP is enabled by default on all supported interfaces to send and receive LLDP packets. The frame contains the MAC address of the device as the multicast address that is not forwarded outside the network, assuming compliance with 802.1D. LLDP supports a set of features that it uses to know information about neighboring devices. These attributes have a specific format known as Type-Length-Value (TLV). Devices that support LLDP can use TLV to receive and send information to their neighbors.
LLDP for media endpoint devices (LLDP-MED) is an LLDP enhancement that works between endpoint devices such as IP phones and network devices as adapters. It specifically provides support for Voice over Internet Protocol (VoIP) applications and provides additional TLVs. LLDP-MED below is compatible with TLV: LLDP-MED TLV capabilities.
