Hi there!
This time, I will share with you a case about how to configure ODUk trails.
Operation procedure:
Step 1 On the main menu of the U2000, choose Service > WDM Trail > Create WDM Trail
Step 2 In the displayed window, set Level to the desired ODUk level, for example, ODU1.
l When Level is set to ODU2, the Rate parameter has two values: Standard Mode and Speedup Mode. When the WDM-side signal is OTU2e, or when the client-side signal is 10GE LAN and Port Mapping is set to Bit Transparent Mapping (11.1 G) for the client-side port, set this parameter to Speedup Mode. In other cases, set this parameter to Standard Mode. l When the trail level is ODUflex, set Service Type to the same value as the service type configured in the NE Explorer. To configure 10GE LAN->ODUflex services for the TTA board, you must set Service Type to PACKET
Step 3 Click Browse on the right of the Source field. In the displayed Select Board Port-Source dialog box, select the desired NE and specify a port on the NE as the source port of the endto-end trail.
In the Select Board Port-Source window, click Working Mode Setting and set Working mode for the port when using the board that supports multiple application scenarios. Follow the same process to specify the sink port.
Step 4 Optional: Specify route constraints. l Method 1: Specify route constraints in the Create WDM Trails window. a. Click the Explicit Link tab. Right-click in a blank area and choose Add from the shortcut menu. In the Add Explicit Link window, search for the existing server trails and set them as the explicit links of the trails to be created. Select the Select Channel check box and select the channels for the explicit links. If no channel is selected for the explicit links, the U2000 automatically calculates route channels. b. Click the Explicit Node tab. Right-click in a blank area and choose Add NE Restriction or Add Board/Port Restriction from the shortcut menu. In the window that is displayed, you can search for NEs, boards, or ports and set them as the explicit nodes for the trails to be created. c. Click the Excluded Node tab. Right-click in a blank area and choose Add NE Restriction from the shortcut menu. In the window that is displayed, you can search for NEs and set them as the excluded nodes for the trails to be created. l Method 2: You can also specify route constraints in the topology view. When you create a service, the server links of the OCh level are automatically filtered and displayed in green in the topology view. After routes are successfully calculated, the working route is displayed in blue between the source and sink NEs.
a. Specify the explicit link. Click a server link in green between the source and sink NEs. In the dialog box that is displayed, specify the explicit server link for the service. Select the Select Channel check box and select the channels for the explicit links. If no channel is selected for the explicit links, the U2000 automatically calculates route channels.
b. Specify the explicit nodes. Right-click the desired NE, choose Set Explicit Node > NE or Set Explicit Node > Board/Port from the shortcut menu, and set NEs, boards, or ports as the explicit nodes for the trails to be created. A selected NE is marked with . Double-click the NE again to cancel the selection.
c. Specify the excluded nodes. Right-click the desired NE, choose Set Excluded Node > NE or Set Excluded Node > Board/Port from the shortcut menu, and set NEs, boards or ports as the excluded nodes for the trails to be created. A selected NE is marked with . Double-click the NE again to cancel the selection.
Step 5 On the Trail Settings tab, select the Auto-Calculation and Activate the trail check boxes.
Step 6 After the trail computation is complete, the server-layer route information of the to-be-created trail, the list of new dynamic cross-connections, and the port attribute list are displayed at the bottom of the topology view. l Click the Server Layer Route Details tab to view the server-layer route information of the working and protection trails. l Click the Create Cross-Connection tab to view new dynamic cross-connections. The user can modify the level of the pass-through cross-connections on the intermediate pass-through node by selecting a value from the Traversal Level drop-down list. The default level is the smallest granularity.
Step 7 Click Apply to complete the trial settings. The Create Trail dialog box is displayed, showing the trail creation progress. Wait until the Operation Result dialog box displays the message Operation succeeded.
That's all, I hope you like it.
Thank you!
