RE: Gigabit Ethernet Collisions [7:73555]
No configuration, just studying for my CCIE re-cert and since I have to take the 350-001 test now, I was looking at this from a testing perspective. Maybe I should have asked if you were Cisco asking a test question [since the QA don't always match reality ;-) and you have to think what Cisco considers the best anser].

Reimer, Fred wrote: Gigastack is Cisco proprietary and not standard Gigabit Ethernet as far as I know. Fred Reimer - CCNA Yes that is correct. In fact you can't configure the gigastack for full duplex, or more correctly shouldn't as I learned the hard way some time ago:( The new 3750 switches have a much better stacking capability.
