Have you guys read the specs of the 3550 layer 3 switches:

24 Gbps switching fabric (Catalyst 3550-12G and 3550-12T), 13.6 Gbps
switching fabric (Catalyst 3550-48), 8.8 Gbps switching fabric (Catalyst
3550-24, 3550-24-DC, and 3550-24-FX)

12 Gbps maximum forwarding bandwidth at Layer 2 and Layer 3 (Catalyst
3550-12G 3550-12T), 6.8 Gbps maximum forwarding bandwidth at Layer 2 and
Layer 3 (Catalyst 3550-48), 4.4 Gbps maximum forwarding bandwidth at Layer 2
and Layer 3 (Catalyst 3550-24, 3550-24-DC, and 3550-24-FX)

17.0 Mpps forwarding rate for 64-byte packets (Catalyst 3550-12G and
3550-12T), 10.1 Mpps forwarding rate for 64-byte packets (Catalyst 3550-48),
6.6 Mpps forwarding rate for 64-byte packets (Catalyst 3550-24, 3550-24-DC,
and 3550-24-FX)

        I think Cisco was feeling some pressure from other companies with
their layer 3 products. For what these cost, you're getting PPS counts
approaching the MSFC2 in a 6500. For roughly $7000! Cisco's going to sell
a lot of these switches, so it makes sense that CCIEs know how to configure
them.

        It's not going to be easy getting one of these for a home lab, but
the IOS concepts and theories are the same. Just find an on-line lab and
spend a couple hours getting cozy with one!

I was told by a proctor at RTP that their goal was REAL "ROUTING AND
SWITCHING" as in
a 5500 with RSM/6500 MSFC-II/2950 etc. etc.

So maybe they ARE going to finally do VLANS and Layer3 switching stuff...
etc.
