 Bridging: transmit LLDP PDU in the same VLAN.
 Flooding: transmit LLDP PDU for all port.
 Transmission Interval
The switch is periodically transmitting LLDP frames to its neighbors for having the
network discovery information up-to-date. The interval between each LLDP
frame is determined by the Transmission Interval value. Valid values are
restricted to 5 - 32768 seconds.
Default: 30 seconds

(Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission Interval
>= (4 * Delay Interval)
 Holdtime Multiplier
Each LLDP frame contains information about how long the information in the
LLDP frame shall be considered valid. The LLDP information valid period is set to
Holdtime multiplied by Transmission Interval seconds. Valid values are
restricted to 2 - 10 times.
TL in seconds is based on the following rule:
erefore, the default TTL is 4*30 = 120 seconds.

 Reinitialization Delay
When a port is disabled, LLDP is disabled or the switch is rebooted a LLDP
shutdown frame is transmitted to the neighboring units, signaling that the LLDP
information isn't valid anymore. TX Reinit controls the amount of seconds
between the shutdown frame and a new LLDP initialization. Valid values are
restricted to 1 - 10 seconds.
 Transmit Delay
If some configuration is changed (e.g. the IP address) a new LLDP frame is
transmitted, but the time between the LLDP frames will always be at least the
value of Transmit Delay seconds. Transmit Delay cannot be larger than 1/4 of
the Transmission Interval value. Valid values are restricted to 1 - 8192 seconds.
This attribute must comply with the rule:
(4 * Delay Interval) ≤Transmission Interval
 LLDP-MED Fast Start
Repeat Count
Confi Us to transmit during the
activation process of the LLDP-MED Fast Start mechanism.

Default: 3 packets
