Read or Read/Write Community string auto fill causing SNMP test to fail when adding a node

Overview

When adding a node to Solarwinds, the SNMP test fails due to the Read or Read/Write community string being auto filled in by the browser. In Wireshark, for the conversation between devices, Solarwinds will try to do a "get" on the Read community string and have it return successfully. If it passes, Solarwinds will attempt to do a "get" on the Read/Write community string and then return successfully. If either community string is wrong or incorrect, then the test will fail regardless of whether you are using only one or both. If either community string is being filled in automatically or auto filled by the browser with the incorrect string then the test will fail.

Environment

All NPM versions

Cause 

The browser is auto filling the community string.

Resolution

Try any of the following:

  • Use another web browser.
  • Clear the browser cache.
  • Go to the Application server and try adding a node via the Web Console.
