Displaying Pseudowire Transmission Statistics
The pseudowire transmission statistics enable analyzing pseudowire traffic
volume, evaluate the end-to-end transmission quality (as indicated by sequence
errors), and jitter buffer performance. By resetting the status data at the desired
instant, it is possible to ensure that only current, valid data is taken into
consideration.
³ To display diagnostic statistics data for pseudowires:
1. Navigate to Monitoring > Applications > Multi-Service over PSN > PW screen,
and select Statistics.
2. On the Statistics screen, select Counters.
3. The Status screen displays the statistics data for the first pseudowire. To
select another pseudowire you can either specify its index number, in the
range of 1 to 640, or sequentially scroll forward or backward by typing F or B.
Unused index numbers are automatically skipped.
4. After selecting a pseudowire, the information displayed on the screen is
updated to display the accumulated statistics data.
You can clear the displayed statistics (that is, reset the monitoring counters) by
typing C: all the counters are simultaneously reset. The counters are also reset
when the MPW-1 is powered up.
Table 4-6 explains the statistics counters parameters.
