How to Configure
There are no configuration tasks specific to the encryption hardware. Both software-based and
hardware-based encryption are configured in the same way. The system automatically detects the
presence of an encryption module at bootup and uses it to encrypt data. If no encryption hardware is
detected, software is used to encrypt data.

Rivest-Shamir-Adelman (RSA) manual keying is not supported.
To achieve maximum benefit from hardware-assisted IP Payload Compression Protocol (IPPCP), it
is suggested that prefragmentation be disabled if IP compression with the Limpel Zif Stac (LZS)
algorithm is enabled on IP Security (IPSec) sessions.
