My boss asked me to update all the IOS in our switches to the "recommended" levels, but when I opened a TAC case, I was told their are no recommended releases. I am interested in the most stable, most up to date versions. Any thoughts? Any versions I should avoid?

And finally,can someone suggest best practices?

Current version: 4507 - Version 12.2(25)EWA3, RELEASE SOFTWARE (fc1)

Current version: 3560 - C3560 Software (C3560-IPBASEK9-M), Version 12.2(35)SE1, RELEASE SOFTWARE (fc1)

There are all IOS, Peoples are choosing them according to needed features. You can't say any IOS most stable or bug less. All IOS has something bugs and errors. Cisco developer is working to resolve as many as they can and they resolves but when they introducenew feature, bugs pop up accordingly.

So, anyway you can choose most recent IOS by


choose platform level, released version etc.
