Dpends on what feature set you currently have in the switch.

Re: IOS version for 4506

You currently have the BASIC L3 3DES feature set.

So if you wanted to go to 12.2.25 you would get the file cat4000-i9k91s-mz.122-25.EWA14.bin to maintain your current feature set.

If you want to go to a newer IOS than that you should probably mention whether you use ssh to access the switch or not. Most of the newer IOS decisions can be whittled down a lot just by deciding if you need ssh access and how much mem you have.

In addition to letting the group know whether you use ssh or not you should also include a "show ver" and "show idprom all" output. Knowing what sup versions you have will help a lot to determining what IOS versions your system can support.
