LLDP-MED
LLDP-MED is an extension of LLDP intended for managing endpoint devices such as Voice
over IP phones and network switches. The LLDP-MED TLVs advertise information such as
network policy and inventory management.
Elements
LLDP-MED Device:
Refers to any device which implements this Standard.
LLDP-MED Device Type:
LLDP-MED devices are comprised of two primary device types:
Network Connectivity Devices and Endpoint Devices.
Network Connectivity Device:
Refers to an LLDP-MED Device that provides access to the
IEEE 802 based LAN infrastructure for LLDP-MED Endpoint Devices. Bridge is a Network
Connectivity Device.
Endpoint Device:
Refers to an LLDP-MED Device at the network edge, providing some aspects
of IP communications service, based on IEEE 802 LAN technology. Endpoint Devices may be a
member of any of the Endpoint Device Classes. Endpoint Devices are composed of three
defined Classes: Class I, Class II and Class III.
Generic Endpoint Device (Class I):
The most basic class of Endpoint Device.
Media Endpoint Device (Class II):
The class of Endpoint Device that supports media stream
capabilities.
Communication Device Endpoint (Class III):
The class of Endpoint Device that directly
supports end users of the IP communication system.
Network Policy TLV
The Network Policy TLV allows both Network Connectivity
Devices and Endpoints to advertise VLAN configuration and
associated Layer 2 and Layer 3 attributes that apply for a
set of specific applications on that port.
Inventory TLV
The Inventory TLV set contains seven basic Inventory
management TLVs, that is, Hardware Revision TLV,
Firmware Revision TLV, Software Revision TLV, Serial
Number TLV, Manufacturer Name TLV, Model Name TLV
and Asset ID TLV. If support for any of the TLVs in the
Inventory Management set is implemented, then support for
all Inventory Management TLVs shall be implemented.
LLDP-MED is configured on the
Global Config
