The switch architecture may be a bit beyond the CCIE lab topic, but here
goes...
Each of the listed controllers represents a Satelite ASIC which controls
a port (GigE) or ports (Fast Ethernet). The ASIC is then responsible
for deciding either to forward the packet onto the switch fabric or to
send it back out a local port.
LOTS more detail in the following:

I think you need a CCO ID to get to that link. If you can't get to it,
respond privately.
Thanks!

Subject: 3550 Ethernet Controllers
Does anyone know why the 3550 ports share ethernet controllers? What
are the side-effects / benefits (?) of this?
