3750E specifications

I decided to look at the specification for the platform I would use the most the WS-C3750E-48TD-S, the specification on this platform

• 48 10/100/1000 ports + 2 X2-based 10 Gigabit Ethernet ports - excellent, would have liked XFP's but nothing wrong with X2 units.

• 64-Gbps, high-speed StackWise Plus stacking- not quite sure how the maths is done on this, is this 32Gb for the whole stack ? ie 8Gb full duplex per cable, if this is the case it is below the other vendors.

• 68-Gbps, wire rate backplane- Why ? you have 48 ports, plus 2 10Gb plus stacking, this totals 168Gb total bandwidth requirements

• Field-replaceable 265WAC power supply and fan tray- good

• 1 rack unit (RU) stackable multilayer switch - industry standard

• IPv6 - hate it

• Ethernet Management port: RJ-45 connectors, 2-pair Cat-5 UTP cabling

• 128-Gbps switching fabric - expecting more

• Stack-forwarding rate of 95 Mpps for 64-byte packets

Forwarding rate:
101.2 Mpps
* IP Base software feature set (IPB) - fine with me.

* Reduction of Hazardous Substances (ROHS) 5 - we couldn't sell it if it wasn't.

Auto configuration is an excellent idea.

Overall not bad, not someting to get very excited about. I have listened to the video on the cisco site and it make some rather interesting statements regarding the resiliance of the stack that I would like to investigate further. I would love them to be true but I am not going to get my hopes up.
