Cisco Catalyst 4000-series switch configuration (CatOS and/or IOS)

I'm going to be undertaking a project to replace an End-of-Support Cisco Catalyst 4006 switch with a new 4506. I'll be gaining access to the 4006 configuration mid-next week, but wanted to get a heads-up on it beforehand.  My questions:

1) Did the 4006 require configuration through the CatOS, as well as the IOS (for the L3 side), as did the earlier Cat 6000's before "Native IOS" became an option?  If the CatOS is required, could the entire switch be managed via the CatOS?

2) Same questions for the 4506.  (Also, is it possible the manage the 4506 solely through a "Native IOS", such as the 65xx-series?)

Want to plan the transition of the configurations as much ahead as possible...

Thanks!

Hit enter too soon.

How the 4000's run is based on the supervisor engine. Sup's I and II are hybrid mode sup's. (CatOS on the supervisor and IOS on the routing engine).

Supervisor III and above are Native mode (IOS only and it controls layer 2 and 3).

Thanks for your help, Don - could I ask a few very quick follow-up questions, and then I'll close and award points?

1) What is the equivalent to "show run" on the CatOS side?
2) How is the CatOS config TFTD'd to an external server (comparable to copy start tftp on the IOS side)?
3) What's the command(s) to switch back and forth between the CatOS and IOS sides ("session" something?  It's been forever...)

Thanks again!
