The Credentials Library stores community string information for SNMP devices in your WhatsUp Gold database to be used whenever a read or write community string is needed to monitor a device. In WhatsUp Gold, credentials are used to limit access to a device's SNMP data. Devices need SNMP credentials assigned to them before SNMP-based Active Monitors can be applied. Configure the following fields to create a SNMPv1 credential:

  • Name. Enter a unique name for the credential. This name displays in the Credentials Library.
  • Description. (Optional) Enter additional information about the credential. This information displays next to the credential in the Credentials Library.
  • SNMP read community. Enter the read community string you want to use for this credential.
  • SNMP write community. Enter the write community string you want to use for this credential.
  • Port. Specifies the UDP port used for SNMP communication. You can modify this value to communicate with devices configured to use a non-standard port.
Note: By default, SNMP uses port 161. When upgrading from earlier versions, existing SNMP credentials are automatically configured to use the default port.
Important: SNMP discovery, testing, and monitoring operations use the port defined in the SNMP credential. If the device is configured to use a non-default port, ensure the Port value matches the device configuration.
