increase the probability that multiple, rather than single changes, are reported
in each transmission.
This attribute must comply with the rule:
(4 * Delay Interval) 
Transmission Interval
◆ Reinitialization Delay – Configures the delay before attempting to re-initialize
after LLDP ports are disabled or the link goes down. (Range: 1-10 seconds;
Default: 2 seconds)
When LLDP is re-initialized on a port, all information in the remote systems
LLDP MIB associated with this port is deleted.
◆ Notification Interval – Configures the allowed interval for sending SNMP
notifications about LLDP MIB changes. (Range: 5-3600 seconds;
Default: 5 seconds)
This parameter only applies to SNMP applications which use data stored in the
LLDP MIB for network monitoring or management.
Information about changes in LLDP neighbors that occur between SNMP
notifications is not transmitted. Only state changes that exist at the time of a
notification are included in the transmission. An SNMP agent should therefore
periodically check the value of lldpStatsRemTableLastChangeTime to detect
any lldpRemTablesChange notification-events missed due to throttling or
transmission loss.
◆ MED Fast Start Count – Configures the amount of LLDP MED Fast Start
LLDPDUs to transmit during the activation process of the LLDP-MED Fast Start
mechanism. (Range: 1-10 packets; Default: 4 packets)
The MED Fast Start Count parameter is part of the timer which ensures that the
LLDP-MED Fast Start mechanism is active for the port. LLDP-MED Fast Start is
critical to the timely startup of LLDP, and therefore integral to the rapid
availability of Emergency Call Service.
