LLDP Globals tab fields
Field
Description
lldpMessageTxInterval
The interval (in seconds) at which LLDP
frames are transmitted on behalf of this
LLDP agent.
lldpMessageTx
HoldMultiplier
The time-to-live value expressed as
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-event is 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
