◆Device Class – Any of the following categories of endpoint devices:
 Class 1 – The most basic class of endpoint devices.
 Class 2 – Endpoint devices that supports media stream capabilities.
 Class 3 – Endpoint devices that directly supports end users of the IP communication systems.
 Network Connectivity Device – Devices that provide access to the IEEE 802 based LAN infrastructure for
LLDP-MED endpoint devices. These may be any LAN access device including LAN switch/router, IEEE 802.1
bridge, IEEE 802.3 repeater, IEEE 802.11 wireless access point, or any device that supports the IEEE 802.1AB and
MED extensions defined by this Standard and can relay IEEE 802 frames via any method.
◆Supported Capabilities – The supported set of capabilities that define the primary function(s) of the port:
 LLDP-MED Capabilities
 Network Policy
 Location Identification
 Extended Power via MDI – PSE
 Extended Power via MDI – PD
 Inventory
◆Current Capabilities – The set of capabilities that define the primary function(s) of the port which are currently enabled. Port
Details – Network Policy
8
◆Application Type – The primary application(s) defined for this network policy:
 Voice
 Voice Signaling
 Guest Signaling
 Guest Voice Signaling
 Softphone Voice
 Video Conferencing
 Streaming Video
 Video Signaling
◆Tagged Flag – Indicates whether the specified application type is using a tagged or untagged VLAN.
◆Layer 2 Priority – The Layer 2 priority to be used for the specified application type. This field may specify one of eight priority
levels (0-7), where a value of 0 represents use of the default priority.
◆Unknown Policy Flag – Indicates that an endpoint device wants to explicitly advertise that this policy is required by the
device, but is currently unknown.
◆VLAN ID – The VLAN identifier (VID) for the port as defined in IEEE 802.1Q. A value of zero indicates that the port is using
priority tagged frames, meaning that only the IEEE 802.1D priority level is significant and the default PVID of the ingress port is
used instead.
◆DSCP Value – The DSCP value to be used to provide Diffserv node behavior for the specified application type. This field may
contain one of 64 code point values (0-63). A value of 0 represents use of the default DSCP value as defined in RFC 2475. Port
Details – Location Identification
8
◆Location Data Format – Any of these location ID data formats:
 Coordinate-based LCI9 – Defined in RFC 3825, includes latitude resolution, latitude, longitude resolution, longitude,
altitude type, altitude resolution, altitude, and datum.
 Civic Address LCI9 – Includes What, Country code, CA type, CA length and CA value.
 ECS ELIN – Emergency Call Service Emergency Location Identification Number supports traditional PSAP-based
Emergency Call Service in North America.
◆Country Code – The two-letter ISO 3166 country code in capital ASCII letters. (Example: DK, DE or US)
◆What – The type of device to which the location applies as described for the field entry. Port Details – Inventory
8
◆Hardware Revision – The hardware revision of the end-point device.
