The differences between the Cisco E and X series switches?

I am doing some research as we are moving to a switching standard accross the board with Cisco.  We are looking at the new E and X series switches,

does anyone here on the forums have any experience with these models?  My biggest question is what are the differences between the two types.

I see that they can provide POE accross all ports and there are some new options for stacking the switches.  Are there any gotchas with either type?

Any feedback here would be great.

Thank you.

Rgds,

Re: The differences between the Cisco E and X series switches?

Basically the 3750x/3560x is the newer models of the 3750e/3560e

before the "E" there was the "G" and so on. so basically the X is the newer version of E

The biggest difference in x and e switches are the powerstacking capabilities in the 3750 ip base and the possibility for 802.1ae, macsec.

Also there are some modules that X supports that is not supported in E.

fx the C3KX-SM-10G module that gives you the possibility to do fx netflow or connect 2 3750x towards eachother.

There is also a difference in that the X has limited lifetime warranty (except power and fans) the E is as far as i know not.

And ofcourse the part with LAN-Base ie L2 it does not exist on the E models either.

but if you choose the Lan base models then you will loose fx the powerstack possibility

If you are looking to buy new switches then i would recomend the X models.

Good luck

Another piece I just wanted to mention is that the 3750X/3560X not only support larger power supplies for PoE, but also redundant power supplies.  This is a pretty nice feature - especially if you've ever tried using an RPS for redundant power in the past.

The X is an improved E.

As noted by the other posters, the two major feature enhancements to the X are power stacking and a module slot. 

I work with both, and if I remember correctly, actual IOS images are same for both.  I too would recommend the X.

Thank you all for this feedback.  Helps to sort through the minutiae to where the tangible benefits are.

Thanks again.

1.  3750E is almost End-of-Sale;

2.  3750X, like the 3750E, supports dual power supply BUT the 3750X support stacked power, dual removable fan module;

3.  3750E supports up to 20.0W of PoE while the 3750X supports up to 30.0W PoE per port (if you get the "PF").

4.  Currently, 3750X does NOT support 10Gb ER SFP+ module.  Only the 3750E does.

5.  The 3750X can support 10Gb copper uplink but the 3750E cannot.

Similarities:

1.  3750E and 3750X run the same IOS codes;

2.  Both have a 32Gbps full duplex backplane;

3.  Both have management ports;

4.  Both have USB ports. 

5.  Both support 10Gb fibre link.

Maybe I should've stated stack backplane.

What is the differance

What is the differance between 10Gb ER SFP+ module and 10Gb fibre link

"10 Gbps fibre link" is a generic term for fibre optic link running 10 Gbps and of various distances, from 100 metres to 100 kilometres (and more).

10 Gbps ER SFP+ is one of those type.  "ER" means "Extended Reach" and supports up to a distance of 40 kms.
