Displays the number of unknown TLVs received by this port. 14.4 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, power via MDI, inventory management, and device location details.  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. TLV Network Policy TLV Description 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. Location Identification TLV The Location Identification TLV provides for advertisement of location identifier information to Communication Endpoint Devices, based on configuration of the Network Connectivity Device it's connected to. You can set the Location Identification content in Location Identification Parameters. If Location Identification TLV is included and Location Identification Parameters isn't set, a default value is used in Location Identification TLV. Extended Power-Via-MDI TLV The Extended Power-Via-MDI TLV is intended to enable advanced power management between LLDP-MED Endpoint and Network Connectivity Devices, and it allows advertisement of fine grained power requirement details, Endpoint power priority, as well as both Endpoint and Network Connectivity Device power status. 236

TLV
Description
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.
Location Identification TLV
The Location Identification TLV provides for advertisement of
location identifier information to Communication Endpoint
Devices, based on configuration of the Network Connectivity
Device it's connected to. You can set the Location
Identification content in Location Identification Parameters. If
Location
Identification
TLV
is
included
and
Location
Identification Parameters isn't set, a default value is used in
Location Identification TLV.
Extended Power-Via-MDI TLV
The Extended Power-Via-MDI TLV is intended to enable
advanced power management between LLDP-MED Endpoint
and
Network
Connectivity
Devices,
and
it
allows
advertisement of fine grained power requirement details,
Endpoint power priority, as well as both Endpoint and Network
Connectivity Device power status.
