So sk169954 from Dec 14th lists R81 for scalable platforms as an existing release, including chassis-based systems such as the 44K as gateway. sk170425 lists the differences of R81 and R81 for scalable platform. And a lot of limitations still. (e.G. pim is broken again, after it was finally supported in R80.20SP Jumbo 295) Has anyone upgraded to that yet on a 40/60k chassis?
Having said that..this being a .0 (say: dot zero) release, I'd be very reluctant to jump at it immediately. There was talk in the CPX 360 Tech Lab about R81.10 being targeted and in EA for scalable platforms?
