NoAuthNoPriv: No authentication algorithm but a user name match is applied to
check packets, and no privacy algorithm is applied to encrypt them.
AuthNoPriv: An authentication algorithm is applied to check packets, but no
privacy algorithm is applied to encrypt them.
AuthPriv: An authentication algorithm and a privacy algorithm are applied to

With AuthNoPriv or AuthPriv selected, configure the authentication mode and
password for authentication. Two authentication modes are provided:
MD5: Enable the HMAC-MD5 algorithm for authentication.
SHA: Enable the SHA (Secure Hash Algorithm) algorithm for authentication. SHA
algorithm is securer than MD5 algorithm.
