4-6 Monitoring Performance MPW-1 MP-4100 Ver. 2.0
Monitoring Pseudowire Services
The pseudowire services monitoring functions include:
• Status data for each pseudowire terminated on MPW-1 ports
• Diagnostic statistics for the current 15-minute interval (interval 0), any
previous 15-minute interval within the last 24 hours for which valid
performance data exists, and data for the current 24-hour interval.
• Transmission performance statistics.
The statistics data is continuously collected, and is stored as long as the
equipment operates. The stored data is deleted when the MPW-1 is reset or
removed, and is also lost when the Megaplex-4100 is powered down.
You can clear the displayed statistics (that is, reset the monitoring counters) by
typing C. The counters are also reset when the MPW-1 is powered up.
The collected data enables the system administrator to monitor the pseudowire
performance, and thus the quality of service provided to users, for statistical
purposes. In addition, when problems are reported by users served by MPW-1,
the collected data can be used for diagnostic purposes, because it can help
identify the source of the problem.
Displaying Pseudowire Status Data
³ To display status data for pseudowires:
1. Navigate to Monitoring > Applications > Multi-Service over PSN > PW screen,
and select Status.
2. The Status screen displays the status 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.
3. After selecting a pseudowire, the information displayed on the screen is
updated to display its status.
Table 4-4 explains the pseudowire status parameters.
