SNMP and MIB import issue

I am having an issue trying to configure SNMP traps for our new phone system. I was given the MIB file attached and when I go to import and set it to process trap I get this message (Failed to convert uploaded file to snmptt mib. (rc: 13)). The MIB is added and when I run the addmib command from the console I get zero errors. The traps are hitting the Nagios server but are logged as unknown traps. Any help or suggestions would be appreciated.

The upload error when trying to add the MIB file using the XI GUI could be caused by a permmission issues with the files / folders the MIB file is uploaded to.
Can you run the following commands and post the output so we can check the permissions?
Code: Select all
ls -alr /etc/snmp
ls -alr /usr/share/snmp/mibs
When you ran the addmib command, this should add the settings to the /etc/snmp/snmptt.conf file for your device.
Take a look at that file and see if the settings are there. If they are, you will have to restart the snmptt daemon after running the addmib command.
Run this as root to do that
Then the next time a trap is received, you will have to configure it in the XI GUI by going to the Admin > Unconfigured Objects menu.
Let us know how it works out.

The results are below. I tried bouncing the service and it made no change. Looking at the snmpttunknown.log I can see where it hits the server with both the host name and ip but shows a unknown trap. I checked unconfigured objects and there is nothing in there related to the sender.

Can you post the following files so I can view them?
Code: Select all
/etc/snmp/snmptt.conf
/etc/snmp/snmptt.ini
Also post one of the entries from the snmpttunknown.log file so I can see the entry.

I looked at your MIB file and the OID from the unknown log file is not in that mib file.
If it is not in that file, the addmib program did not add it to the snmptt.conf file so if it is not in there, the snmptt daemon cannot translate it and it is unknown.
See if you can contact the manufacturer of the device to see if you can get an updated MIB file with that OID in it.
