Currently there is no way to hide, remove, or destroy the off page reference icons. In SPECTRUM version 9.2 a new user preference to hide off page references within all Topology views will be introduced.
A "workaround" some users have implemented is to move all of the off page reference icons on top of another so it looks like there is only one OPR in the view.
Another "workaround" is to use Global Collections to model e.g. the core devices. The Global Collection topology will display connections between collection members but will not display any off page references.
Can off page reference (OPR) models be destroyed or hidden within SPECTRUM OneClick?
After discovery runs, there are lots of off page references.
How can off page references be removed without destroying the associated model?
Causes of this problem:
The off-page reference icon is a special purpose topology icon. It represents a device that is directly connected to a device in the current view but which is modeled in another layer.
