interface status on alert

I have create an alert that notified when an interface received is less that 1 bps and set the custom status to critical. 

The alert is working fine, but the interface status cannot change to Critical.

i got this " "test" action has failed Execution of CustomStatus action with Entity type - Orion.NPM.Interfaces failed. CustomStatus alerting action works only with Orion.Nodes."

Can anybody help me please.  I want to change the interface status to WARNING or CRITICAL status when an interface does not received any packets
