application layers on top of the protocol, in order to achieve these related properties.
Initially, a Network Connectivity Device will only transmit LLDP TLVs in an LLDPDU. Only after
an LLDP-MED Endpoint Device is detected, will an LLDP-MED capable Network
Connectivity Device start to 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 of an LLDP frame being lost during transmission between neighbors, it is recommended
to repeat the fast start transmission multiple times to increase the possibility of the neighbors
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.
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 should be normalized to within 0-90 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 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.
The Map Datum is used for the coordinates given in these options:
WGS84: (geographical 3D) - World Geodesic System 1984, CRS Code 4327, and
Prime Meridian Name: Greenwich.
NAD83/NAVD88: North American Datum 1983, CRS Code 4269, Prime Meridian
Name: Greenwich; the associated vertical datum is the North American Vertical
Datum of 1988 (NAVD88). This datum pair is to be used when referencing locations
on land, not near tidal water (which would use Datum = NAD83/MLLW).
NAD83/MLLW: North American Datum 1983, CRS Code 4269, Prime Meridian
Name: Greenwich; the associated vertical datum is Mean Lower Low Water (MLLW).
This datum pair is to be used when referencing locations on water/sea/ocean.
