About a month ago, I used a tool on Cisco.com where I could specify a WAN modules and see what IOS trains were compatible with it. For example, I know the VWIC-1MFT-G703 interface is compatible with the 12.1T train but not the 12.1 train. However, I cannot seem to find this tool again. I would like to get all my routers to the same IOS level, and this was a nice way to make sure it would work on all configurations. I was not done cross referencing all modules with all trains, and I can't find the tool again. Please help!
