Configuring ITO
Preconfigured Elements

The following kinds of traps can be intercepted:
Well-defined traps, such as system coldstart, network interface
up/down, and so forth.
HP OpenView internal traps, for example, those originating from
netmon.
ITO Distributed Event Interception
ITO Distributed Event Interception allows you to intercept SNMP traps
on systems other than the ITO management server. This provides
performance benefits by allowing the local processing of messages.
Automatic actions, for example, can be triggered and executed directly on
the node or in the subnet, instead of being first forwarded to the
management server.
Basic Configuration
1. Make sure that SNMP devices have only one SNMP destination,
or that there is only one system serving as the NNM collection
station for the management server (preferably, the collection
station connected via the fastest network). The destination
system(s) for SNMP devices on HP-UX nodes is set in the
/etc/SnmpAgent.d/snmpd.conf file with a
trap_dest:<nodename> statement.
2. If NNM is not running on the node where you want to intercept
events, add the following line to the opcinfo file on that node:
SNMP_SESSION_MODE NO_TRAPD
3. Assign and distribute the trap template to the node.
Configuration to Avoid Duplicate Messages
Make certain that an ITO agent (and thus, an ITO event interceptor)
runs on all NNM collection stations. Use the Print Collection Station
application in the NNM Tools application group to verify which
managed nodes are set up as NNM collection stations.
