I.2 Setting the SNMP trap converter

(1) Setup

Set up the SNMP trap converter before using it. Setup is also required if you re-install JP1/Base over a previous installation.

1. Execute the imevtgw_setup command to register the SNMP trap converter in NNM.

   Execute the command as follows:

   /opt/jp1base/bin/imevtgw_setup

   The SNMP trap converter is registered in the NNM process management.

2. Make sure that the SNMP trap converter is registered correctly.

   Check the NNM process as follows.

   Execute the command as follows:

   /opt/OV/bin/ovstatus

   If the IMEvtgw process appears under the ovw process, the SNMP trap converter has been registered correctly.

(2) Starting the SNMP trap converter

To start the SNMP trap converter:

1. Edit the action definition file for converting SNMP traps (imevtgw.conf).

   For details on the action definition file, see I.4(1) Action definition file for converting SNMP traps (imevtgw.conf).

2. Edit the SNMP trap conversion filter file (snmpfilter.conf).

   Specify the conditions for all SNMP traps to be converted into JP1 events, using the appropriate enterprise and event names listed in trapd.conf. For details on how to do this, see I.4(2) SNMP trap conversion filter file (snmpfilter.conf).

3. Start NNM.

   SNMP trap converter begins when NNM starts.

   To start the NNM background process, execute the following command:

   /opt/OV/bin/ovstart

4. Confirm that the converter functions normally.

   Generate an SNMP trap that can be converted, and then confirm that the trap was successfully converted into a JP1 event.

(3) Changing a setting while a trap is active

If you change the settings in the action definition file for converting (imevtgw.conf) SNMP traps or filter file for converting SNMP traps (snmpfilter.conf), apply the new settings as follows.

If you edit the SNMP trap conversion action definition file

After editing the definition file, restart the SNMP trap converter.

If you edit the SNMP trap conversion filter file

You can apply the new settings without stopping the SNMP trap converter by executing the xnmevents command (provided by NNM) with the -event option.

(5) Clearing the SNMP trap converter

Before you uninstall JP1/Base, clear the SNMP trap converter registered in the NNM process management.

1. Execute the /opt/OV/bin/ovstatus command and make sure that IMEvtgw (the SNMP trap converter) is inactive.

   If IMEvtgw is running, execute the /opt/OV/bin/ovstop command to end the NNM daemon processes.

2. Execute the following command:

   /opt/jp1base/bin/imevtgw_setup -d

   This command deletes the imevtgw.exe file and imevtgw file from the NNM directory, and clears the setting for starting the SNMP trap converter from the NNM process management.
