Searching CCO for some keywords, I've found two interesting documents: http://www.cisco.com/warp/public/620/ios_11_1cc.html tells that IOS 11.1CC(17) was the basis for IOS 12.0(1). In other words, if 11.1CC(17) was good for you, 12.0(1) (and possibly 12.0(1a)) would also meet your requirements. http://www.cisco.com/warp/public/620/ios_12_0s.html tells that the IOS 11.1CC line will be replaced by IOS 12.0S. Cisco sources indicate that 12.0(3)S will be the first public release, and 12.0(4)S would be a better choice. Does someone know the release date of 12.0(2)S ? I'm trying to estimate a schedule for IOS 12.0(4)S deployment, based on release date of 12.0(2)S and two increments of 7 weeks for each release. Rubens Kuhl Jr.
