advertise LLDP-MED TLVs in outgoing LLDPDUs on the associated port. The

LLDP-MED application will temporarily speed up the transmission of the

LLDPDU to start within a second, when a new LLDP-MED neighbour has been

detected in order share LLDP-MED information as fast as possible to new

neighbours.

Because there is a risk of an LLDP frame being lost during transmission between

neighbours, it is recommended to repeat the fast start transmission multiple times

to increase the possibility of the neighbours receiving the LLDP frame. With Fast

start repeat count

it is possible to specify the number of times the fast start

transmission would be repeated. The recommended value is 4 times, given that 4

LLDP frames with a 1 second interval will be transmitted, when an LLDP frame

with new information is received.

It should be noted that LLDP-MED and the LLDP-MED Fast Start mechanism is

only intended to run on links between LLDP-MED Network Connectivity Devices

and Endpoint Devices, and as such does not apply to links between LAN

infrastructure elements, including Network Connectivity Devices, or other types

of links.

Coordinates Location

Object

Description

Latitude

Latitude

SHOULD be normalized to within 0-90 degrees with a maximum of 4

digits.

It is possible to specify the direction to either North of the equator or South of the

equator.

Longitude

Longitude

SHOULD be normalized to within 0-180 degrees with a maximum of 4

digits.

It is possible to specify the direction to either East of the prime meridian or West

of the prime meridian.

Altitude

Altitude

SHOULD be normalized to within -32767 to 32767 with a maximum of 4

digits.

It is possible to select between two altitude types (floors or meters).

Meters

: Representing meters of Altitude defined by the vertical datum specified.

Floors

: Representing altitude in a form more relevant in buildings which have

different floor-to-floor dimensions. An altitude = 0.0 is meaningful even outside a

building, and represents ground level at the given latitude and longitude. Inside a

building, 0.0 represents the floor level associated with ground level at the main

entrance.
