Adding and editing a new SNMP v3 credential
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. For more information, see Using Credentials.
To add or edit a new SNMP v3 credential:
- From the WhatsUp Gold web interface, go to . The Credentials Library appears.
- Click to create a new credential or from the list of current credentials, select the credential you want to change, then click .

- . Enter the context needed to identify specific SNMP instances on your network. This box is optional.
- . If required, select the authentication protocol for this SNMP credential.
- . Select the algorithm method for authenticating SNMP v3 packets. MD5 creates a 128 bit digital signature and SHA-1 creates a 160 bit digital signature.
- . Enter the authentication password.
- . Re-enter the authentication password a second time for confirmation.
- If supported, and an authentication protocol was selected for the SNMP v3 device, select the encryption protocol for the SNMP credential.
- . Select the algorithm method for encrypting SNMP v3 packets. DES56 uses a 56 bit encryption scheme and AES-128 uses a 128 bit encryption scheme.
- . Enter the encryption password.
- . Re-enter the authentication password a second time for confirmation.
