Encryption Preferences
The following configuration options allocate preferences to the encryption method for
encrypting data on the link. A lower value indicates greater preference. A value of 0 disables the
option.
3DES
The preference level for the Triple-DES algorithm.
AES (128 bits)
The preference level for the 128-bit AES algorithm.
AES (192 bits)
The preference level for the AES algorithm using 192 bits.
AES (256 bits)
The preference level for the AES algorithm using 256 bits.
Authentication Preferences
The following configuration options allocate preferences to the selected authentication
methods. As above, a value of 0 disables the particular authentication method and lower values
indicated greater preference than higher values. So, for example if MAC SHA1-96 is the preferred
method for authentication, this option is given the value 1 and the other options given a value of
2 or greater. If all these parameters are set to the same value, the router automatically uses
them in the following order: SHA1, SHA1-96, MD5, MD5-96.
MAC MD5
The preference level for MAC MD5.
MAC MD5-96
The preference level for MAC MD5-96.
