username snmpv3 authentication

This command specifies the authentication protocol to be used for the specified user. The valid authentication protocols are none, md5 or sha. If you specify md5 or sha, the login password is also used as the SNMPv3 authentication password and therefore must be at least eight characters in length. The username is the user name associated with the authentication protocol.


You must enter the username in the same case you used when you added the user. To see the case of the username, enter the show users command.
