Quoth someone below: "2948G-L3 -- Basically a 48-port router!"
Yes, as aforementioned, the 2948G-L3 *can* reside quite readily in Layer 3
land, and configured that way, per port.
But, L3 land isn't really switch land, and to just view the G-L3 as a 48
port high-speed router is not getting your Cisco 'bang-for-the-buck". Don't
forget ISL/802.1q, VLAN fun, I)ntegrated R)outing and B)ridging and B)ridge
V)irtual I)nterfaces. Those nifty, but, for me at least, complex
integrations, are a real instructive challenge to your BCSN tasks. The
2948G-L3 is a fairly new addition to the fleet.
To that end, there are a couple of URLs providing *some* guidance for setup.
Be warned, however, that a good grasp of Cisco LAN Switching should be a
prerequisite. Oddly enough, Cisco Press has a book of that title. It's a
worthy read.

There is one other link at the Cisco site concerning ISL links to a 2924XL.
Don't have that one handy.
If any of you gentle readers have some more sample configs, please don't
hesitate to contact me, as I'm still fighting the battle.

Subject: Layer 3 switching
I know there has been much discussion on this in the past, but I want to
make sure that I understand it. Layer 3 switching is the equivalent of
routing, but is usually referred to as Layer 3 switching because it's
designed for high speed LAN traffic.
Assuming the above is correct what are some examples of a regular routers
vs. layer 3 switch? I'm guessing the 2500 series routers would be regular
but what would be a good example of a layer 3 switch?
Thanks,
