Parameters Config
Transmit Interval:
Enter the interval for the local device to transmit LLDPDU to its
neighbors. The default value is 30.

TTL (Time To Live) value used in an LLDPDU. TTL = Hold
Multiplier * Transmit Interval. The default value is 4.
Transmit Delay: Enter a value from 1 to 8192 in seconds to specify the time for the
local device to transmit LLDPDU to its neighbors after changes
occur so as to prevent LLDPDU being sent frequently.
The default
value is 2.
Reinit Delay: This parameter indicates the amount of delay from when LLDP
status becomes "disable" until re-initialization will be attempted.
The default value is 3.
