Session Agent monitoring (SNMP trap)

Hi guys,

 

I understand that when a session agent's state changes From I (In-Service) to O (Out-of-Service), the SD is able to send out a SNMP trap.

 

My quietist is that does the SD also send a SNMP trap when the session agent's state changes in another direction, i.e. from O (Out-of-Service) to I (In-Service). If so, how do we differentiate the two scenarios?

 

Basically my monitoring element want to take different action under the two scenarios.

 

Thanks in advance,

 

Chris
