Whenever I get a good idea for a post its come out of something I have done that I think others might find helpful or I was looking for something but did not find a good answer. In first case I usually will search for content before posting because if someone else did it better I see no reason for meto do it again. In second case I usually take my time to do it right and when I am working on it someone else usally beast me too it so I really just don’t have much content.
Thats what happened with the 6500 upgrade post. Check out Ruhann’s post at http://blog.ru.co.za/2010/03/18/upgrading-a-cisco-6500/ He did a great job in summing up the steps so I am not going to waste time doing that here.
I was going to do a great post on the modular IOS on the 6500 pre-SXI3 and post SXI3 but so far I am not sure exactly where Cisco is going with the newest modular IOS (12.2(33)SXI3 and later) because the hallmark of the old install process was the “install file” command. You can read all about it at http://www.cisco.com/en/US/docs/ios/swmod/configuration/guide/sw_mod_instl_cfg.html. But that process is now gone, look at the release notes for 12.2(33)SXI3: http://www.cisco.com/en/US/docs/ios/12_2sx/12_2sxi/12_2_33_sxi3_newfeatlist.html and you will se that process is deprecated.
So what now? Just install it like any old IOS upgrade and you have modular IOS. Pretty simple. Now make sure you read up on modular IOS before you chose it as it has some hardware limitation (some SIP modules for example.) Most people who have gone to modular IOS have been happy but not everyone. It has taken awhile to get fully stable which is funny because its supposed to be more stable. So read up on it and hopefully with SXI4 I will have something to add to this post.
