Monitor Performance
This chapter explains how to enable and view performance monitoring statistics for the CiscoONS15600SDH. Performance monitoring (PM) parameters are used by service providers to gather, store, threshold, and report performance data for early detection of problems. For more PM information, details, and definitions, refer to the CiscoONS15600SDH Reference Manual.
Before You Begin
Before performing any of the following procedures, investigate all alarms and clear any trouble conditions. Refer to the CiscoONS15600 SDH Troubleshooting Guide as necessary.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
1. 
F58 Enable Intermediate-Path Performance Monitoring—Complete as needed.
2. F59 Monitor Optical Performance—Complete as needed after enabling performance monitoring.
Note For additional information regarding PM parameters, refer to the Digital transmission surveillance section in ITU G.826, G.827, G.829. M2101, and M2120, in Telcordia GR-1230-CORE, GR-820-CORE, and GR-253-CORE, and in the ANSI document entitled Digital Hierarchy - Layer 1 In-Service Digital Transmission Performance Monitoring.
NTP-F58 Enable Intermediate-Path Performance Monitoring
Note Regenerator Section and Multiplex Section performance monitoring is enabled when the port(s) are in service (IS). To enable performance monitoring of VC4 traffic through the nodes, you must enable IPPM for the path(s) being monitored.
Step1 Complete the "DLP-F36 Log into CTC" task at the node you want to monitor. If you are already logged in, continue with Step2.
Step2 In node view, double-click an optical (traffic) card. The card view appears.
The Cisco ONS 15600 SDH has the following optical (traffic) cards:
•OC48/STM16 LR/LH 16 Port 1550
•OC48/STM16 SR/SH 16 Port 1310
•OC192/STM64 LR/LH 4 Port 1550
•OC192/STM64 SR/SH 4 Port 1310
Step3 Click the Provisioning > AU4 tabs. Figure8-1 shows the AU4 tab in the Provisioning window.

Step1 In node view, double-click an STM-N card. The card view appears.
Step2 Click the Performance tab.
Step3 Click the 15 min radio button.
Step4 Click Refresh. The PM parameters appear in 15-minute intervals that are synchronized with the time of day.
Step5 View the Current column to find PM counts for the current 15-minute interval.
Each monitored performance parameter has corresponding threshold values for the current time period. If the value of the counter exceeds the threshold value for a particular 15-minute interval, a threshold crossing alert (TCA) is raised. The number represents the counter value for each specific performance monitoring parameter.
Step6 View the Prev-n columns to find PM counts for the preceding 15-minute intervals.
Note If a complete 15-minute interval count is not possible, the value has a yellow background. An incomplete or incorrect count can be caused by changing node timing settings, changing time zone settings, changing the count by using the clear function, replacing a card, resetting a card, or changing port states.
Step7 Return to your originating procedure (NTP).

Step1 In node view, double-click an STM-N card. The card view appears.
Step2 Click the Performance tab.
Step3 Click the 1 day radio button.
Step4 Click Refresh . The PM parameters display in one-day (24-hour) intervals that are synchronized with the time of day. For PM parameter definitions refer to the CiscoONS15600SDH Reference Manual.
Step5 View the Current column to find PM counts for the current one-day interval.
Each monitored performance parameter has corresponding threshold values for the current time period. If the value of the counter exceeds the threshold value for a particular one-day interval, a TCA is raised. The number represents the counter value for each specific performance monitoring parameter.
Step6 View the Prev-n columns to find PM counts for the preceding one-day intervals.
Note If a complete count over a one-day interval is not possible, the value has a yellow background. An incomplete or incorrect count can be caused by changing node timing settings, changing time zone settings, replacing a card, resetting a card, changing port states, or adjusting and clearing the counter.

Step3 Click Baseline .
Note The Baseline button clears the PM count shown in the Current column, but does not clear the PM counts on the card. When the current time interval expires or the window view changes, the total number of PM counts on the card and on the window appear in the appropriate column. The baseline values are discarded if you change views to a different window and then return to the Performance tab window.
Step4 View the Current column to observe changes to PM counts for the current time interval.
Step5 Return to your originating procedure (NTP).

Caution The Clear button can mask problems if used incorrectly. This button is commonly used for testing.
Step1 In node view, double-click an STM-N card. The card view appears.
Step2 Click the Performance tab.
Step3 Click Clear .
Step4 In the Clear Statistics menu, choose one of the following options:
•Displayed statistics : This option erases from the window display all PM counts that are currently displayed in the Performance tab window.
•All statistics for port n : This option erases from the window display and card memory all PM counts associated with the selected port. This means the 15-minute and one-day, near-end and far-end PM counts for the selected port are cleared from the card and the window display.
•All statistics for card : This option erases from the window display and card memory all PM counts associated with the selected card. This means the 15-minute and one-day, near-end and far-end PM counts for the selected card are cleared from the card and the window display.
•All statistics for selected parameters : This option erases from the window display and card memory all PM counts associated with the selected parameters. For example, if the 15 min and the Near End radio buttons are selected, all near-end PM counts in the current 15-minute interval are erased from the card and the window display.
Step5 Click Yes to clear the selected statistics.
Step6 View the displayed columns to verify that the selected PM counts have been cleared.
Step7 Return to your originating procedure (NTP).

•1 Minute : This option sets the window to autorefresh at one-minute time intervals.
•3 Minutes : This option sets the window to autorefresh at three-minute time intervals.
•5 Minutes : This option sets the window to autorefresh at five-minute time intervals.
Step4 Click Refresh . The PM counts for the new time interval appear.
Depending on the selected autorefresh interval, the PM counts shown automatically update when each refresh interval is complete. If the autorefresh interval is set to None, the PM counts are not updated unless you click the Refresh button.
Step5 Return to your originating procedure (NTP).
