F5 LTM Custom SNMP query not working

Hi Team,

I'm trying to configure the Custom SNMP query on my LTM to send VIP/Pool UP/Down status to the HP NNM.

I have edited the /config/user_alert.conf file as per article K3727. In article below point has been mentioned.

****The object ID is in standard object identifier (OID) format, and within the following range:

.1.3.6.1.4.1.3375.2.4.0.300 through .1.3.6.1.4.1.3375.2.4.0.999****

I can able to receive the alerts only if the following OIDs are used.

 snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.301"

 snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.302"

 snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.303"

 snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.304"

if i user any OID other then this 4 alerts are not coming to the NNM. Is there any limitation to use other than this 4, or am i doing anything worngly.
