Use the SNMP Credential Test tool (**Tools** icon > **Device** > **SNMP** **Credential** **Test**) to determine a successful SNMP community string for a device. For the selected device, the tool tries all the community strings listed in the **Settings** icon > **Setup** > **Credentials** page using the same order as NetMRI's internal guessers. Testing stops when a successful string is found or all strings have been tried.

> ⚠️ **Note**
> ⚠️ 
> ⚠️ The SNMP Credentials Test can be run on any device, including those not known to NetMRI.
