SNMPv3 Authentication Profiles

For regions containing SNMPv3-accessible devices, determine the minimum acceptable default authentication profiles, the authentication profiles appropriate for each region, and the unique authentication credentials in use on specific devices (if any). Also determine the authentication and privacy protocols in use within your network.

For SNMPv3 communication, NNMi supports the following authentication protocols:

  • HMAC-MD5-96
  • HMAC-SHA-1

For SNMPv3 communication, NNMi supports the following privacy protocols:

  • DES-CBC
  • TripleDES
  • AES-128
  • AES-192
  • AES-256

You can specify one (or no) authentication protocol and one (or no) privacy protocol for each specific node or region setting.

Note Use of the TripleDES, AES-192, or AES-256 privacy protocols requires the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files library, which is installed automatically as part of the NNMi installation process. If you accidentally delete the library, you can restore it by following the procedure in NNMi Configuration Issues.
