snmp alarm auto clear

Hi ,

I am developing a large NMS solution using java. The application is recieveing SNMP alarm successfully From port 162 coming from different network elements and showing them in a jtable. Manually I can remove alarm trap entry from Jtable.

Now challange is: how the application can determine the error issue is solved and regarding alarm remove from jtable.

Case Example:

1)A port is down at cisco switch, cisco send a snmp saying port is down. Assme snmp codes with a id :8887

2)user made the cisco port up,cisco send snmp trap that port is up with a new snmp id:8888
Now as the problem solved, how application can determine to remove alarm holding id:8887?

Can any one help who worked with NMS?

Thanks!
