In some cases when a change is done on the profile level for a sub interface , the change is not synced to the edges in this profile correctly and the sub interface is not created on the edge,
The issue is caused by bug #154266 where the main interface is overridden at edge-level, the sub interfaces under that interface are not resolved properly in edgeHeartbeat and that is causing this issue.
Issue is seen on all VCO versions before 6.4.
Workaround: Do any dummy change in the UI for a particular edge with issue, then the sub interfaces get resolved by the UI which makes it work even when main interface is overridden at edge-level.
Issue will be resolved in VCO version 6.4
