The Report.SNMP.System Summary activity in CatTools is very basic in its operation.
It runs a series of SNMP Gets to collect basic system information from your device, and also provides you with 5 custom fields for you to enter further OIDs to return additional SNMP data.
With regards to your SNMP activity, are you using any of the SNMP Custom fields or just the basic defaults?
Are you seeing any errors in the CatTools Info Log when the activity is run?
Custom fields with confirmed working OIDs but I also tried without and got the same results. When I run it I get:
***SNMP timeout or unknown error
I don't believe it is a networking issue as I can see the request go from the cattools program to my Fortinet but my device doesn't respond back. Even when I configured it for debug mode, I don't see the firewall respond at all to the query from the cattools program. I have repeated this test on multiple devices and have received the same results.
Based off this previous information, I'm guessing the program isn't formulating the snmp request correctly to the fortinet.
I discovered the cause of the issue, my SNMP community string has an ampersand in it. As soon as I removed it, I didn't get the errors anymore.
