When checked the configured PoE (Power Over Ethernet) information for the interface is included in
LLDP-MED information transmitted.
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 -2097151.9 to 2097151.9 with a maximum of 1 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:
WGS84 : (Geographical 3D) - World Geodesic System 1984, CRS Code 4327, 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.
