Requested Paths
Displays a list of permitted Paths which specifies the Path(s) into which the
MAC may be inserted Possible values are Local, Secondary-alternate,
Primary-alternate, concatenated-alternate, secondary-preferred, Primary-
preferred, Concatenated-preferred, and Thru.
Port LER Thresholds View
The SynOptics FDDI Port LER Thresholds view contains Line Error Rate
information for the SynOptics FDDI 5000 Series. This view provides the
following information:
SMT Index
Displays a unique value for each port.
Port Index
Displays a unique value for each port within a given SMT.
LEM Reject Count
Displays a link error monitoring count of the times a link has been rejected.
LEM Error Count
Displays the aggregate link error monitor error count, set to zero only on
station initialization.
LCT Failure Count
Displays the count of the consecutive times the link confidence test (LCT) has
failed during connection management.
LER Cutoff
Displays the link error rate estimate at which a link connection will be
broken. It ranges from 10**-4 to 10**-15 and is reported as the absolute value
of the base 10 logarithm. The default is 7.
LER Alarm
Displays the link error rate estimate at which a link connection will generate
an alarm. It ranges from 10**-4 to 10**-15 and is reported as the absolute
value of the base 10 logarithm of the estimate. The default is 8.
LER Estimate
Displays a long term average link error rate. It ranges from 10**-4 to 10**-15
and is reported as the absolute value of the base 10 logarithm.
LER Condition
Displays the condition becomes active when the value of
fddiPORTLerEstimate is less than or equal to fddiPORTLerAlarm. This will
be reported with the Status Report Frames (SRF).
