To use a Cat 6000/6500 in native mode you need MSFC(s).
One of my native 6500 has 278 ports - you don't want to do a show run on
that, you will be there all day! Use TFTP to copy the config, look at config
in CiscoWorks etc.
To see one interface - Show run interface fa3/33 - this is possible on any
IOS based device
To get a short summary of ports - show interface range - output the same as
CatOS
You can bulk program interfaces - (config)# interface range ........
Cisco have been saying that they will be migrating to IOS for all their
switches so there is one common cli for all their products. This is why the
latest switches are IOS - new 2950 and 3550 series and the sup III for 4000.
Once they remove the extra cost for native mode on Cat 6K expect to see more
of them.
I personally prefer the native mode. It is a bit slower to config but more
powerful. You can get load stats for an interface without having to use
SNMP. The 6K can do load balancing (extra license required) which acts like
a big local-director. You have a startup and a running config so you can
easily rollback a change, the debug command, and you don't have to configure
the switch and the MSFC separately. I would use native IOS more but not all
our switches have MSFCs and there is the extra cost.
If you read the Cisco Press book Cisco LAN switching - CCIE series it talks
about the pro's/con's for both switching routers (Cat 8500) and routing
switches (MLS) and that native IOS has the benefits of both.

Steve,
You make a good point ... the Cat 6500 can be configured in either "hybrid"
or "native" mode (requires the installation of different IOS, so you don't
just toggle back and forth).
When configured as hybrid mode, the switch uses standard set-based IOS and
the MSFC is an IOS-based router with VLAN interfaces. When configured as
"native" mode, the switch and MSFC are controlled from one IOS-based console
with FastEthernet (or GigaEthernet) interfaces (like the 3550).
Most people prefer hybrid mode because you can bulk-program ports rather
than repeat the commands over and over for each FastEthernet interface.
Imagine "show config" for a router with 192+ FastEthernet interfaces. Also,
in Hybrid mode you can "show port" and get a short summary.
I assumed the Lab would want a Cat 6500 to test candidates in Hybrid mode.
