any help?

Thanks in advance

AES encryption support has been introduced in Cisco IOS? 12.2(13)T. There are no hardware based IPSEC.

When you do encryption in software the throughput would be reduced. It also can have negative impact on CPU load as these features will processed in software.

Actually there are many hardware based IPSEC / encryption solutions is the cisco portfolio.

The ISR routers (all), the PIX/ASA, the older 17xx and 26xx with the appropriate modules, the 7200 with the SA, the 6500/7600 blades, these are all hardware based encryption solutions.

See the following document for a comparison of performance for different platforms:

Note: there is not much data on software based encryption because is not adequate for any serious deployment but only the most casual low speed setup.

Hope this helps, please rate post if it does!
