SNMPv3 authentication

SNMPv3 was originally defined using the User-Based Security Model (USM), which contains a private list of users and keys specific to the SNMPv3 protocol.

To use the USM based SNMPv3-specific users, you'll need to create them explicitly:

createUser [-e ENGINEID] username (MD5|SHA) authpassphrase [DES|AES]

           [privpassphrase]

MD5 and SHA are the authentication types to use. DES and AES are the privacy protocols to use. If the privacy passphrase is not specified, it is assumed to be the same as the authentication passphrase. Note that the users created will be useless unless they are also added to the VACM access control tables, see section “Access control”.

CAUTION! The minimum passphrase length is 8 characters.
