Device Type
Any LLDP-MED Device is operating as a specific type of LLDP-MED Device,
which may be either a Network Connectivity Device or a specific Class of
Endpoint Device, as defined below.
A Network Connectivity Device is a LLDP-MED Device that provides access
to the IEEE 802 based LAN infrastructure for LLDP-MED Endpoint Devices
An LLDP-MED Network Connectivity Device is a LAN access device based
on any of the following technologies:
1. LAN Switch/Router.
2. IEEE 802.1 Bridge.
3. IEEE 802.3 Repeater (included for historical reasons).
4. IEEE 802.11 Wireless Access Point.
5. Any device that supports the IEEE 802.1AB and MED extensions that can
relay IEEE 802 frames via any method.
An Endpoint Device a LLDP-MED Device that sits at the network edge and
provides some aspect of IP communications service, based on IEEE 802
LAN technology.
The main difference between a Network Connectivity Device and an
Endpoint Device is that only an Endpoint Device can start the LLDP-MED
information exchange.
Even though a switch always should be a Network Connectivity Device, it
is possible to configure it to act as an Endpoint Device, and thereby start
the LLDP-MED information exchange (In the case where two Network
Connectivity Devices are connected).
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 digit. 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:
