3.6.8 Deleting Links
You can delete one or multiple links from the Link table. You can delete a single link from the Network Map.

Step 2 Click OK in the confirmation dialog box.
Step 3 For multiple link deletion, complete the following substeps:

•To remove a valid autodiscovered link from CTM, you must remove the topology neighbors from both NEs at the end of the link.
•CTM can delete physical links even if there is an autodiscovered SONET/SDH link.
