Workflow for interface

Workflow for interface

Hi ALL.
I need help with Workflow for my regional routers.
I want create request to SDP if router has certain interface down more than 60 min?
My plan is:
1) if interface goind down, OpManager run workflow
2) Workflow add delay 60 mins
3) after 60 mins delay workflow does recheck this interface and if it still down = create case to SDP
But I cant fing any actions about interface/device recheck ((
How i can create this workflow??
