4500X IOS-XE Version Choice

[Randall Nieland]

We have a pair of 4500X switches using VSS and running the deferred 3.5.0E code, so that obviously needs to be upgraded. I'm wondering what experiences there might be from the community regarding the 3.6.x line. 3.6.0E adds support for SFP-H10GB-CU1-XM cables in different lengths that will help with cabling some systems, but are there significant reasons why we should not upgrade at this point?

I see plenty of open caveats for 3.5.x and 3.6.x, many of them the same items, and I don't see anything in 3.6.x that scares me, but I'm new to this line of switches and figured I'd see if there are other opinions.

Thanks!

Apparently, 3.6.X codes are flagged as "long live" codes.  So this means that sticking to 3.6.X is a good idea.

We also have a pair of 4500X VSS and recently upgraded them to cat4500e-universalk9.SPA.03.07.00.E.152-3.E.bin as a verified stable version.
