So, I've been reading many posts, Cisco documentation and release notes and testing various versions of 12.2(33)SXH and SXI in a lab environment. Based on all the Cisco marketing fluff, modular IOS seems like the way to go for reliability. Real world experience from many smart people on this list seem to have the opposite opinion. I've read things indicating that the platform is going to be going all modular in the future (and one thing that said the opposite??). I'm further very confused by Cisco dropping the install command from SXI3 onward so there is no more patching which was one of the advantages to using it.
This is a sign that the modular IOS won't be the way in the future for IOS on Catalyst 6500. With the new Supervisor the IOS-XE high availability model is going to be used (however it is still to early to get into gory details), so rather than going deep down to the sub-process level patchability which was the target for the modular IOS (and it seems it wasn't widely used), 6500 with the classical IOS is going back to the developments Cisco made to its NSF/SSO and ISSU features. Also, that way, IOS code base for the 6500 will benefit the most from the code already written and present for other platforms. Until there's formal CCO statement of direction, You should contact your account team to get more details. -- "Everything will be okay in the end. | Łukasz Bromirski If it's not okay, it's not the end." | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
