SNMP notifications sent with authentication and DES privacy return the error "UNKNOWNUSERNAME, WRONGDIGEST." What action resolves this?

The error "UNKNOWNUSERNAME, WRONGDIGEST" indicates a problem with the authentication credentials. Since DES privacy is being used, the SNMPv3 configuration requires both authentication and privacy passwords to be correctly set. authPriv is the security level that provides both authentication and encryption (privacy). Therefore, configuring the correct authentication and privacy passwords using authPriv will resolve the issue. Incorrect options: authNoPriv only provides authentication but no privacy. Since the problem statement mentions DES privacy, authNoPriv is not the correct security level. Configuring only the authentication password with authPriv is insufficient because the privacy password is also required when privacy is enabled.
