153
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.
Coordinates Location
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.
Map Datum
The Map Datum is used for the coordinates given in these options:
