SNMP v3

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 SNMP v3 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.
• Username. Enter the username that is configured for the SNMP agent. This username is included in every SNMP packet in the authentication header. An SNMP device, upon reception of a packet, uses this username to look for configured authentication and encryption parameters and applies them to the received message.
• Context. (Optional) Enter the context needed to identify specific SNMP instances on your network.
• Authentication. If required, select the authentication protocol for this SNMP credential.
  • Protocol. Select the algorithm method for authenticating SNMP v3 packets. MD5 creates a 128 bit digital signature, SHA-1 creates a 160 bit digital signature and SHA-256 creates a 256 bit digital signature.
  • Password. Enter the authentication password.
  • Confirm password. Re-enter the authentication password a second time for confirmation.
• Encryption. If supported, and an authentication protocol was selected for the SNMP v3 device, select the encryption protocol for the SNMP credential.
  • Protocol. Select the algorithm method for encrypting SNMP v3 packets. DES56 uses a 56 bit encryption scheme, AES-128 uses a 128 bit encryption scheme, AES-192 uses a 192 bit encryption scheme, and AES-256 uses a 256 bit encryption scheme. Triple DES encryption may also be selected.
  • Password. Enter the encryption password.
  • Confirm password. Re-enter the authentication password a second time for confirmation.

Note: SNMP v3 passwords are limited to 64 characters.
