Does anyone know if feature is available on EX? I've used it on SRX with RPM probe to making gateway/routing changes and now i have to do it on EX switch. Running 12.1 and services ip-monitoring is not there. Are Event scripts is the way to go here?
Yes, services ip-monitoring is not supported on EX and you can achieve something similar with event policy.
