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:
• 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). Use this
datum when referencing locations on land. If land is near tidal water, use nad83-mllw (below).
• nad83-mllw - North American Datum 1983, CRS Code 4269, Prime Meridian Name: Greenwich;
The associated vertical datum is mean lower low water (MLLW). Use this datum when referencing
locations on water, sea, or ocean.
Example coordinate-based location configuration
The following shows an example coordinate-based location configuration for the Sears Tower, at the
following location.
103rd Floor233 South Wacker DriveChicago, IL 60606
device(config)#lldp med location-id coordinate-based latitude 41.87884 resolution 18
longitude 87.63602 resolution 18 altitude floors 103 resolution 30 wgs84
The above configuration shows the following:
• Latitude is 41.87884 degrees north (or 41.87884 degrees).
• Longitude is 87.63602 degrees west (or 87.63602 degrees).
• The latitude and longitude resolution of 18 describes a geo-location area that is latitude 41.8769531
to latitude 41.8789062 and extends from -87.6367188 to -87.6347657 degrees longitude. This is an
area of approximately 373412 square feet (713.3 ft. x 523.5 ft.).
• The location is inside a structure, on the 103rd floor.
• The WGS 84 map was used as the basis for calculating the location.
Example coordinate-based location advertisement
The coordinate-based location advertisement will appear similar to the following on the remote device,
and in the CLI display output on the Brocade device (show lldp local-info ).

Configuring civic address location
When you configure a media Endpoint location using the address-based location, you specify the
location the entry refers to, the country code, and the elements that describe the civic or postal
address.
To configure a civic address-based location for LLDP-MED, enter commands such as the following at
the Global CONFIG level of the CLI.
device(config)#lldp med location-id civic-address refers-to client country US elem 1
