Initially, a Network Connectivity Device will only transmit LLDP
TLVs in an LLDPDU. Only after an LLDP-MED Endpoint Device is
detected, will an LLDP-MED capable Network Connectivity Device
start to advertise LLDP-MED TLVs in outgoing LLDPDUs on the
associated port. The LLDP-MED application will temporarily speed
up the transmission of the LLDPDU to start within a second, 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 that a LLDP frame being lost during
transmission between neighbors, it is recommended to repeat
the fast start transmission multiple times to increase the
possibility for that the neighbors has received the LLDP frame.
With Fast start repeat count it is possible to specify the number
of times the fast start transmission is repeated. The
recommended value is 4 times, giving that 4 LLDP frames with a 1
second interval will be transmitted, when a 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 between Network Connectivity Devices, or to other
types of links.
Coordinates Location
Object Description
• 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
