For changing the Traps to HP OpenView style, you need to send an SNMP command to the device given below:
snmpset .1.3.6.1.4.1.3854.1.2.2.1.60.0 i X
Where IP is the IP address of the sensorProbe. Community default is ‘public’. and X can take 3 values: 1 (WhatsUP gold style), 2 (HP OpenView Style), 3(both Style). By default, the X value set is 1.
