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 neighbor has been

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

neighbors.

Because there is a risk that a LLDP frame being lost during transmission

between neighbors, it is recommended to repeat the fast start transmission

multiple times to increase the possibility for that the neighbors has received the

LLDP frame. With Fast start repeat count it is possible to specify the number of

times the fast start transmission is repeated. The recommended value is 4 times,

giving that 4 LLDP frames with a 1 second interval will be transmitted, when a

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 between Network Connectivity Devices, or to

other types of links.

Coordinates Location

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.
