DESCRIPTION
"This object indicates whether a change in the received CDL
Defect Indications, including the implicit end-to-end path
defect indication as well as the CDL defect indication bits in
the CDL OAM field, causes a notification to be generated.
disabled: Received CDL aggregate defect indication bit changes
do not cause coCdlRxAggDefectIndChange notifications to be
generated, and CDL flow defect indication changes from the
CDL network at path terminating interfaces do not cause
coCdlFromCdlNetFlowDIChange notifications to be generated.
enabledAtTerminatingInterfaces: A coCdlRxAggDefectIndChange
notification is generated whenever
- the received hop-by-hop forward defect indication (FDI-H)
or the received hop-by-hop backward defect indication bit
(BDI-H) changes at a hop terminating interface, or
- the received end-to-end (aggregate path) defect
indication bit (FDI-E) changes at an aggregate path
terminating interface.
A coCdlFromCdlNetFlowDIChange notification is generated
whenever a CDL flow defect indication, i.e. implicit
end-to-end path forward defect indication or end-to-end
path backward defect indication bit, from the CDL network
changes at a path terminating interface.
enabledAtAllInterfaces: a coCdlRxAggDefectIndChange
notification is generated whenever a received CDL aggregate
defect indication bit changes on any interface, and a
coCdlFromCdlNetFlowDIChange notification is generated
whenever a CDL flow defect indication, i.e. implicit
end-to-end path forward defect indication or end-to-end
path backward defect indication bit, from the CDL network
changes at a path terminating interface.
To minimize the probability of prematurely reacting to
momentary signal variations, a soak time may be incorporated
into the notification in the following manner. A notification
is generated after a defect is first detected, when the defect
persists for a period of time that exceeds the set soak
interval specified by coCdlDefectIndSetSoakInterval. A
notification is generated after a defect stops being detected,
when the defect does not appear over a period of time that
exceeds the clear soak interval specified by
coCdlDefectIndClearSoakInterval.
When changes in CDL defect indications are received for
multiple interfaces within a short time span, notifications
should be deferred so that each notification is generated at
least one coCdlDINotifyThrottleInterval after the previous
notification."
