I need to know if the IOS Firewall processes traffic in hardware or software. I would like to take advantage of the feature, but don't want it to have an impact on performance. Oh, and right now we can't justify the $ for FWSM modules.
IOS Firewall processes traffic in software.I will never recommend to run the Cisco IOS firewall on the Sup720 as it can impact the over all performance of the Sup engine. I would recommend to use dedicated hardware FWSM module on the chassis for a better performance.

You can create upto 250 virtual firewalls within the same module.
