I have installed several versions of the Cisco 2500 IOS in attempt to find an IOS that supports crypto. I have used 11.2, 12.2, 12.0, and 12.3 without any luck. (I was not able to turn up any results after an hour or of google searching to answer my question). So does anyone know if there is a IOS version that supports crypto? Or is there no IOS versions (for the 2500) that have this functionality.
