Adding and editing a new SNMP v3 credential
The Credentials system 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 (on page 75).
To add or edit a new SNMP v3 credential:
1 Access the Credentials Library.
2 Click New to create a new credential or from the list of current credentials, select the
credential you want to change, and then click Edit.

Name. Type a name for the credential. This name displays in the Credentials Library.
Description. Type a short description. This description displays next to the credential
in the Credentials Library.
Username. Type 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.

network. This box is optional.

credential.

Confirm password. Re-type 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.
