16-4 Cisco Prime Network 4.3.2 User Guide Chapter 16 Managing DWDM Networks Viewing G.709 Properties Viewing G.709 Properties The Telecommunication Standardization Sector (ITU-T) Recommendation G.709 provides a standardized method for transparently transporting services over optical wavelengths end to end. A significant component of G.709 is the FEC code that improves performance and extends the distance that optical signals can span. To view G.709 properties: Step 1In the Vision client, double-click the device on which DWDM is configured. Step 2In the Inventory window, choose Physical Inventory > Chassis and navigate to the interface configured for DWDM. Step 3In the content pane, click G709 Details. Figure 16-2 and Figure 16-3 provide examples of the G709 Info Properties windows. Most devices provide the information shown in Figure 16-2.

16-10 Cisco Prime Network 4.3.2 User Guide Chapter 16 Managing DWDM Networks Viewing Performance Monitoring Configuration Step 5To close the G709 Info Properties window, click the upper right corner. Viewing Performance Monitoring Configuration Performance monitoring parameters are used to gather, store, set thresholds for, and report performance data for early detection of problems. Thresholds are used to set error levels for each performance monitoring parameter. During the accumulation cycle, if the current value of a performance monitoring parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) can be generated. The TCAs provide early detection of performance degradation. The Vision client enables you to view the configuration settings for performance monitoring. Performance monitoring statistics are accumulated on a 15-minute basis, synchronized to the start of each quarter-hour. They are also accumulated on a daily basis starting at midnight. Historical counts are maintained for thirty-three 15-minute intervals and two daily intervals. To view performance monitoring configuration settings: Step 1In the Vision client, double-click the device on which DWDM is configured. Step 2In the Inventory window, choose Physical Inventory > Chassis and navigate to the interface configured for DWDM. Step 3In the content pane, select the performance monitoring configuration settings you want to view: To view the performance monitoring 15-minute configuration settings, click PM 15-min Settings. To view the performance monitoring 24-hour configuration settings, click PM 24-hour Settings. The Client DWDM PM Settings Properties window is displayed as shown in Figure 16-4. ODU Alert Counters Tab (Displayed for devices such as the Cisco 7600 series.) Type Type of OTU alert, such as SD-BER or SF-BER. Threshold Threshold set for the type of alert.

Max TCA If enabled, indicates a TCA is generated if the value of the parameter exceeds the maximum threshold during the performance monitoring period. If disabled, TCAs are not generated if the maximum threshold is exceeded. Min Threshold Minimum threshold configured for the parameter. Min TCA If enabled, indicates a TCA is generated if the value of the parameter drops below the minimum threshold during the performance monitoring period. If disabled, TCAs are not generated if the value drops below the minimum threshold. Table 16-4 Client DWDM PM Settings Properties Window and Tabs (continued) Field Description
