As stated previously, the 2950 is essentially an L2 switch only, the
3550 can be either L2 or L3. To configure the L3 version of the 3550
you can check out:

But how do you configure multilayer switching/routing? Is it like an
RSM/MSFC ?
i.e.
interface vlan 20
 ip address x.x.x.x

or like a cat2948G-L3 where you have to subinterface the port to trunk
it
and create BVI's to route
i.e.
interface fastethernet 0/1.1
 bridge-group 1

interface BVI1
 ip add x.x.x.x

The only thing that the documentation says is that you are supposed to
type
'no switchport' and then assign an ip address
i.e.
interface fastethernet 0/1
 no switchport
 ip address x.x.x.x

So is it a multiport router? How do you route the vlans? How about
trunks?
And if it is truly a multilayer switch, wouldn't we have to enter mls
commands somewhere?

Any help is appreciated.

Thanks
Aurelio

Hi Ted,

With Layer 3 image running on a CAT3550, it is as good as having a
router in

your network. You can run the following rotuing protocols: OSPF, RIP,
IGRP
and EIGRP. IS-IS is currently not supported. You could even configure
some
of the ports as a routed port.

CAT2950 is a purely layer 2 switch and you cannot run any routing
protocol
on it.

I hope this answers your question.
