LLDP Globals tab fields
Field		Description
lldpMessageTxInterval		The interval (in seconds) at which LLDP
		frames are transmitted on behalf of this
		LLDP agent.
lldpMessageTx		The time-to-live value expressed as
HoldMultiplier		a multiple of the object. The actual
		time-to-live value used in LLDP frames,
		transmitted on behalf of this LLDP agent,
		is expressed by the following formula:
		TTL = min(65535, (lldpMessageTxInterval
		*lldpMessageTxHoldMultiplier))
		For example, if the value of
		lldpMessageTxInterval is 30, and
		the value of lldpMessageTxHoldMultiplier
		is 4, the value 120 is encoded in the TTL
		field in the LLDP header.
lldpReinitDelay		The lldpReinitDelay indicates the delay
		(in seconds) from when the LLDP Port
		AdminStatus of a particular port is disabled
		until reinitialization begins.
lldpTxDelay		The lldpTxDelay indicates the delay (in
		seconds) between successive LLDP
		frame transmissions initiated by value or
		status changes in the LLDP local systems
		MIB. The recommended value for the
		lldpTxDelay is set by the following formula:
		1 <= lldpTxDelay <= (0.25 *
		lldpMessageTxInterval)
lldpNotificationInterval		This object controls the transmission
		of LLDP notifications. The agent
		must not generate more than one
		lldpRemTablesChange notification-event
		in the indicated period, where a
		notification-eventis the "transmission of
		a single notification PDU type to a list
		of notification destinations." If additional
		changes in lldpRemoteSystemsData
		object groups occur within the indicated
		throttling period, these trap-events must
		be suppressed by the agent. An NMS
		must periodically check the value of
		lldpStatsRemTableLastChangeTime to
		detect any missed lldpRemTablesChange
		notification-events, for example, due to
		throttling or transmission loss. If notification
