I ran a test in my lab. I created one event that only generates an event. I created another event that generates an alarm. I added an Event Condition rule to the first event to check the value of the Network_Address attribute id 0x12d7f and if equal to a specfic value, generate the 2nd event that asserts an alarm. Here are my EventDisp configurations for the events:
0xfff00133 E 0 R CA.EventCondition, "({a 0x12d7f} == {A 10.241.249.74})" , "0xfff00134 -:-"
0xfff00134 E 0 A 3,0xfff00134
Worked like a charm.
