limited LLDPU space and to reduce security and system integrity issues that can
come with inappropriate knowledge of the network policy.
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.
