Thank you for your question.
There isn't anything "special" that has to be configured in the ATLAS. The SNMP Access has to be ENABLED, and the SNMP COMMUNITIES has to be configured with the IP address, Priviledges, and community names for GET
and SET (read community and write community names) for the device trying to access the SNMP (or MIB walk).
Under SYSTEM CONFIG and EVENT LOGGING, you can set the SYSTEM CONTROLLER to INFO and then go to SYSTEM STATUS and view the EVENT LOG while doing the MIB walk. If there is an authentication error you will get an "SNMP Authentication Failure" event in the log. If there is an IP mismatch then no events will show in the log. (Also, if the MIB walk is successful, there are no events in the log.)
Hope this helps,
Thanks patrick, I got it to work! I had to set snmpwalk to use snmp version 1. I swear I tried that last week, oh well
