If an explicit path is added, this link will be selectable as shown in the Path Options section of the create window in Figure A-53. By clicking an explicit path link, a non-editable Explicit Path Viewer in Figure A-54 appears.
Figure A-53 Path Options

Create TE Backup Tunnel
To access the TE Protection SR window for managing backup tunnels, go to Service Inventory > Inventory and Connection Manager > Traffic Engineering Management > Create TE Backup Tunnel. The TE Protection SR window in Figure A-62 appears.
Figure A-62 TE Protection SR
The TE Protection SR window contains the following elements:
The columns in the tunnel list provides the following information:
•Op—Current SR operation on the tunnel. This can be one of the following:
–ADD—Indicates a newly added tunnel, either calculated by the system or entered by the user.
–MODIFY—Indicates a modified existing tunnel.
–DELETE—Indicates an existing tunnel to be deleted, either computed by the system or originated by the user.
•Tunnel ID—Unique tunnel identifier used within ISC TEM.
•Head—Hostname of the head router.
•Dest—Hostname of the destination router.
•T#—Tunnel number on the head router.
•BW Quota—The amount of bandwidth this backup tunnel can protect. The router limits the LSPs that can use this backup tunnel so that the sum of the bandwidth of the LSPs does not exceed the specified amount of bandwidth. If there are multiple backup tunnels, the router will use the best-fit algorithm.
•Deploy Status—Tunnel deployment status.
•Conformance—Indicates whether the tunnel is found to be conformant when running discovery. A tunnel is non-conformant if it has a non-zero bandwidth reservation and a zero hold or setup priority. If a tunnel is entered through ISC TEM, it is always conformant.
The following actions can be performed (buttons):
•Close—Close the Topology Display applet if open.
•Display—Open a Topology Display for the network and highlight the selected backup tunnel(s). The selected tunnel(s) is/are marked in color with directional arrows.
•Details—Open the TE Tunnel Details window, which provides type, status, LSP, and other information about the tunnel.
•Create—Create a backup tunnel.
•Edit—Edit the selected backup tunnel.
•Delete—Delete the selected backup tunnels.
•Audit SR—Audit protection of protected elements using all existing backup tunnels and proposed changes in the SR.
•Save & Deploy (Figure A-63)—For committing resource changes in the SR. Two options for saving and deploying Backup Tunnel SRs to the network:
–SR Tunnels Only—Deploy all tunnel changes in the SR, or if no changes were made to the SR, use this to re-deploy the SR that was in Requested or Invalid state.
–Force Deploy All Tunnels—Force deployment of all tunnels in this SR. This could be useful when previous provisioning of the SR has failed, so that it is necessary to force through the deployment of all tunnels in the SR.
Figure A-63 Save & Deploy Tunnels
•Cancel—Cancel the operation and return to the Traffic Engineering Management Services window.
The tunnel SR search tool allows you to look for particular tunnels by selecting tunnel characteristics in the drop-down menu tunnels with and specify matching criteria in the Matching field:

–Tunnel Status—Tunnel deployment status.
–Conformance—Conformant or non-conformant tunnel.
•matching/equal—Specify matching criteria for your search. Wildcards are accepted. matching changes to equal if Head, Dest Device is selected in the drop-down menu. For equal, the exact host name of the head or tail device must be entered (wildcards not accepted).
•Find—Click the Find button when the search criteria has been entered.

To view the task log for a TE task, three sequential steps are required:
1. Access the Task Runtime Actions window.
2. Select a runtime action to reach the Runtime Actions window.
3. Select the desired log in the Task Log window.
Each window in this process is described as follows.
Note Specific instructions for how to view a task log for a TE Discovery task are found in the TE Discovery Task Logs, page 3-6.
Task Runtime Actions
To access the Task Runtime Actions window, go to Monitoring > Task Manager. Select Logs in the table of contents on the left side of the Tasks window. The Task Runtime Actions window in Figure A-68 appears.
