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.

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)
