T(> The 2948G-L3 and the 4908G-L3 I believe are Prefix/ASIC based. T(> I believe the 3550-EMI is as well, but I'm not familiar with that T(> equipment.

All 3550s are prefix/ASIC based, EMI or SMI doesn't matter.

Anyone know about the: Cisco Catalyst 3750 ?

3750s are also prefix/ASIC based. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
