3.6.7 Modifying Links

Note Table 3-14describes the fields in the Modify Link wizard.

Step 1 Open the Modify Link wizard using one of the following methods:

•In the Link table, select a link and choose Edit > Modify Link.

•In the Network Map, select a link and choose Configuration > Modify Link.

Step 2 In the Link Attributes panel, modify the following information, as needed:

•Name

•Description

•Cost

•Shared risk link groups

Note If you modify the SRLG value, you receive the warning popup “There might be circuits routed with diverse SRLG constraints on this link. Changing risk link groups might affect the diversity constraint.” Click OK; then, verify the SRLG value that you entered.

Step 3 Click Next until you reach the Finish panel.

Step 4 Verify the link summary and click Finish.

Note After certain topology reconfigurations that involve removing fiber, the Network Map might not report the correct links. This problem occurs because the CTM server is not synchronized with the new network topology and cannot retrieve network or link updates. This problem applies only to CTC-based NEs. The workaround is to remove the links completely by deleting the SDCC termination on the ports, rather than by simply unplugging the fiber cable.
