Chapter 7 Performance Monitoring
Monitoring SONET Performance
Viewing Section Total Statistics
Total statistics are performance statistics collected since the previous midnight. So just before midnight
there are almost 24 hours of statistics available, at midnight the statistic counters are reset, and after
midnight the system starts accumulating new data. To view total statistics for a single line, enter the
lsssectiontst command, specifying the slot and line number delimited by a period. The system displays
the total statistics for the specified line:
=======================================================================
Sonet Section Total Statistics (lsssectiontst)
=======================================================================
Sonet section Slot.Line : 9.1
Errored Seconds : 87293
Severely Errored Seconds : 87293
Severely Errored Framing Seconds : 87293
Coding Voilations : 0
To view total statistics for all lines, enter the lsssectiontsts command. The system displays total
statistics for all lines:
=======================================================================
Sonet Section Total Statistics for all Lines (lsssectiontsts)
=======================================================================
Slot.Line Error Secs SeverSecs FrameSecs CodingVoilations
========= =========== ========= ========= ===========
9.1 87293 87293 87293 0
9.2 63892 63892 63892 0
Clearing Section Total Statistics
To clear statistics, enter the clrssectiontst command, specifying the slot and line number delimited by
a period and the statistical counter to clear. Specify the counter as follows:
1—None
2—All
3—ES
4—SES
5—SEFS
6—CV
For example, the following command clears all total section statistics for slot 9 line 1:
clrssectiontst 9.1 2
Viewing Section Interval Statistics
Interval statistics are collected by each interface for the previous 24 hours of operation. The 24 hours
are broken into 96 15-minute intervals, where interval 1 is the most recent and 96 is the oldest. As time
progresses, the system drops the oldest interval and adds the latest one, creating a sliding 24-hour
window that moves with time.
