I am in the process of getting ready to quote a customer whom has some Cisco Catalyst switches that are soon coming end of Support. The affected models are 3550 and 2950 switches.
I am looking at 3560 Catalyst switches to replace the 3550 and 2950 models. I am confused about specifically what to recommend within this line for the following reason: Cisco makes Catalyst "3560-X" , "3560-E", and just "3560" switches.
While examining each of these in the Cisco Products Quick Reference Guide, it is somewhat difficult to take away what differentiates a 3560-x from a 3560-e, 3560-E from a 3560, and so on.
Can anyone give me a 10,000 foot level overview of why I would pick an X , an E, or just a 3560?
Thank You.
Kevin

High level:
-E series offers wire-rate fabric and PPS, and 10 gig; for 3750 series, also offers double stack bandwidth and smarter stack bandwidth managment.
-X series offers improved PoE support, especially with 3750 series.
If you're okay with 10/100 ports, 3560, original, will likely do just fine. If planning to use 10/100/100 ports or if you need lots of PoE power, you might want to examine performance requirements carefully.

Ok, let's call each model the "plain", "E" and the "X".
The plain model is the cheapest of them all. You have alot of variables to choose this one aside from price: number of 10/100BaseTx ports, number of 10/100/1000BaseTx ports, 1 Gb SFP ports, PoE capable (up to 15.4 w per port on a first-come-first-serve-until-full).
What differentiates the "E" and the "X" from the plain model is 10Gb interface. The "E" and the "X" can support a combination of two 10Gb interface (fibre optic), four 1Gb SFP or a combination of one 10Gb and two 1Gb SFP. The "E" support DUAL power supply while the "X" support power-stacking (up to four chassis). And as Joseph has mentioned, the "E" support PoE up to 20.0 w while the "X" support PoE of up to 30.0w (on a first-come-first-serve-until-full).
Both the "E" and "X" has management ports for out-of-band-management. It's not a switchport. The "E" and "X" also come with USB ports and you can boot your IOS via USB.
If you have more than one switch in a rack then it's recommended that you use the 3750 because you can stack them together to form one logical switch. If your stack goes beyond 6 then I'd recommend that you make two switch stacks as operating a stack of 7 to 9 switches can be scary.
