The above location ID formats are defined in the following sections.
Coordinate-based location
Coordinate-based location is based on the IETF RFC 3825 [6] standard, which specifies a Dynamic
Host Configuration Protocol (DHCP) option for the coordinate-based geographic location of a client.
When you configure an Endpoint location information using the coordinate-based location, you
specify the latitude, longitude, and altitude, along with resolution indicators (a measure of the
accuracy of the coordinates), and the reference datum (the map used for the given coordinates).
To configure a coordinate-based location for an Endpoint device, enter a command such as the
following at the Global CONFIG level of the CLI.
Brocade(config)#lldp med location-id coordinate-based latitude
-78.303 resolution 20 longitude 34.27 resolution 18 altitude meters 50 resolution

latitude <degrees> resolution <bits>
longitude <degrees> resolution <bits>
altitude floors <number> resolution <bits> | meters <number> resolution <bits>
<datum>
latitude <degrees> is the angular distance north or south from the earth equator measured
through 90 degrees. Positive numbers indicate a location north of the equator and negative
numbers indicate a location south of the equator.
resolution <bits> specifies the precision of the value given for latitude. A smaller value increases
the area within which the device is located. For latitude, enter a number between 1 and 34.
longitude <degrees> is the angular distance from the intersection of the zero meridian. Positive
values indicate a location east of the prime meridian and negative numbers indicate a location
west of the prime meridian.
resolution <bits> specifies the precision of the value given for longitude. A smaller value increases
the area within which the device is located. For longitude resolution, enter a number between 1
and 34.
altitude floors <number> is the vertical elevation of a building above the ground, where 0
represents the floor level associated with the ground level at the main entrance and larger values
represent floors that are above (higher in altitude) floors with lower values. For example, 2 for the
2nd floor. Sub-floors can be represented by non-integer values. For example, a mezzanine
between floor 1 and floor 2 could be represented as 1.1. Similarly, the mezzanines between floor 4
and floor 5 could be represented as 4.1 and 4.2 respectively. Floors located below ground level
could be represented by negative values.
resolution <bits> specifies the precision of the value given for altitude. A smaller value increases
the area within which the device is located. For floors resolution, enter the value 0 if the floor is
unknown, or 30 if a valid floor is being specified.
altitude meters <number> is the vertical elevation in number of meters, as opposed to floors.
resolution <bits> specifies the precision of the value given for altitude. A smaller value increases
the area within which the device is located. For meters resolution, enter a value from 0 to 30.
<Datum> is the map used as the basis for calculating the location. Specify one of the following:
