With this in mind LLDP-MED defines an LLDP-MED Fast Start interaction
between the protocol and the application layers on top of the protocol, in
order to achieve these related properties. 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 neighbour has been detected in order
share LLDP-MED information as fast as possible to new neighbours.
Because there is a risk of an LLDP frame being lost during transmission
between neighbours, it is recommended to repeat the fast start
transmission multiple times to increase the possibility of the neighbours
receiving the LLDP frame. With Fast start repeat count it is possible to
specify the number of times the fast start transmission would be repeated.
The recommended value is 4 times, given that 4 LLDP frames with a 1
second interval will be transmitted, when an 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 Network Connectivity
Devices, or other types of links.
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 meridia
n.
