The ASA 5585-X IPS SSP and the Normalizer Engine
The majority of the features in the Normalizer engine are not used on the ASA 5585-X IPS SSP, because
the ASA itself handles the normalization. Packets on the ASA IPS modules go through a special path in
the Normalizer that only reassembles fragments and puts packets in the right order for the TCP stream.
The Normalizer does not do any of the normalization that is done on an inline IPS appliance, because
that causes problems in the way the ASA handles the packets.
