The IPS service on the ASA 5500-X Series requires Cisco IPS Sensor Software Release 7.1.4 or later. The next-generation firewall service (application visibility, monitoring, and reporting) requires ASA CX Software Release 9.1.1 (the Cisco ASA Software Release must be 9.1.1).
About IPv4 and IPv6
Q. Is ASA software capable of being deployed in a mixed IPv4 and IPv6 environment?
A. ASA can be deployed in mixed IPv4 and IPv6 deployments, and it prepares customers for this imminent migration. ASA capability helps customers prepare for migrating to IPv6 by delivering critical v4 to v6 translation. It provides stateful NAT64 and NAT66, DHCPv6 relay, DNS64, and Unified ACL to simplify policy configuration in a mixed v4 and v6 environment. ASA delivers IPv6 remote access connections with less than a 15 percent performance impact compared with IPv4 traffic. In contrast, other offerings experience an average of 80 percent degradation in performance when transitioning from an IPv4 to an IPv6 traffic pattern.
