SNMPv3 security parameters

SNMPv3 includes an authentication feature that, when selected, requires users to enter their names, an authentication protocol, an authentication key, and their desired security level when invoking a command.

If the security level is set to authNoPriv, authentication is performed by using the user's authKey to sign the message being sent. The authProtocol parameter must be MD5. The authKey parameters are generated from a passphrase that must have a minimum of eight characters. If the security level is set to authNoPriv, you must enter the following parameters:
Parameter Command-line option Description
securityName -u Name User name must not exceed 31 characters.
authProtocol -a (MD5) Authentication type must be MD5.
Note: Data ONTAP does not support SHA authentication protocol.
authKey -A PASSPHRASE Passphrase with a minimum of eight characters.
securityLevel -l (authNoPriv) Security level: must be Authentication, No Privacy.
Note: Data ONTAP does not support retrieving MIB values using the AuthPriv and noAuthNoPriv security levels.
context -n CONTEXTNAME Sets the context name used for SNMPv3 messages.
