Hi, we have a Cisco 4506 switch that is running IOS 12.2(20)EWA3. We are wanting to enable WCCP to use transparent proxying however I need to upgrade the IOS to support this feature. Going through the Software Advisor the latest it is telling me I can go to is 12.2(25). I guess I have several questions:
1) What version/build do I need to go to to enable WCCP? From what I can see it is at least 12.2(31)
2) Our version of IOS appears to be an ED version and to get above build 25 I need to move to an SG version or something like that. Is this correct?
3) The software advisor is telling me I don't have enough boot flash memory to perform the upgrade. Below is a copy of my show hardware and show file systems commands:
