IBM Magstar 3494 manual Trouble Shooting, Receiving Snmpd Traps on the Monitor Station

Sending TESTM Messages

Once SNMP has been con®gured, send an SNMP trap to ensure that SNMP is con®gured correctly. The TESTM trap allows a test message to be sent to the monitor stations which have been set up to receive the SNMP trap messages.

To send a TESTM SNMP trap, select Send TESTM Trap from the SNMP Options menu. Selecting this menu item creates a dialog box, which allows entry of a string to send to all the monitor stations for which the Library Manager is con®gured (See Figure 138 ).

Figure 138. TESTM SNMP Trap Message Pop-Up Window

Most problems sending SNMP messages are related to network con®guration. If the monitor station does not receive the trap, check the SNMPD window located on the Library Manager to see if the SNMPD trap message was sent. If the daemon shows the message, make sure that the network path is correct to the monitor station.

Trouble Shooting

Most problems encountered will be related to the site network or software. The following is a list of things to check on the Library Manager to ensure SNMP is working correctly.

1.Make sure that the SNMPD process is running.

2.Make sure that the monitor station can be ªpingedº from a Service Window. If the monitor station cannot be pinged, then there is a network con®guration problem which must be corrected. The SNMP trap will never get to the monitoring station unless the network con®guration problem is corrected.

3.Generate a TESTM trap message, and check the SNMPD window to see if it was sent. To do this, use Ctrl + Esc to bring up the Window List, and use the mouse or arrow keys to highlight the SNMPD process. You should see the TESTM trap message in the window. If there are any errors, then the daemon is not being started correctly.

Receiving SNMPD Traps on the Monitor Station

All the Library Manager trap types follow a very similar format. Each Library Manager SNMP trap message generated has the same beginning format. This helps the programmer on the monitor station handle the different Library Manager SNMP trap message types.

Each ®eld in the Library Manager SNMP trap message is space delimited. This allows the programmer to tokenize the incoming Library Manager SNMP trap message.
