We want to use the Neighbor is down alert, but only for MPLS interfaces. So I created an interface custom property called MPLS_Interface and set it to True on the interfaces that we care about. I then copied the alert Neighbor is down and I am trying to scope the alert to only use interfaces with that custom property. My issue is that It does not let me select from interfaces, only from Nodes in the first box. Interfaces is not an option. Any idea why? Are neighbors not defined by interface and only by nodes?
