I recently upgraded my CW LMS from v2.6 to 3.1.
Apparently in the topology maps some links between some equipments are not present after the upgrade.
Does someone else have the same issue?
After the upgrade, make sure you run a full Campus Data Collection. Additionally, some known topology issues have been fixed in the latest CM 5.1.3, so consider applying the 5.1.3 SP from Common Services > Software Center > Software Update.
