Symptom
Post upgrade from 17.3.2 to 17.3.4a ip domain lookup got disabled automatically. This lead to tracking and UTD issues and we have to enable it manually.
Conditions
Upgrade triggered the issue. Reload also causes the issue to resurface.
Workaround
* Reattaching the template resolves the issue. We are able to see that domain lookup gets enabled again.
*Change it to CLI mode and configure it manually. Post which we can change it to vmanage mode again.
* Use a CLI Add on template with "ip domain lookup" configuration, so that even after reload/Upgrade the issue doesn't resurface
Further Problem Description
NCS is trying to sync config of device with vmanage which is triggering the issue.
