    I'm just guessing here, but I'd say longevity. The 4200 has been available for sale for a number of years, and now that the 4300 is out, seemingly as its successor, I think it won't be too long before we see an EoL notice for the 4200.

     

    The new series has pretty much the same use case. But, as you said, it supports higher speeds. It also has more memory, faster CPU, likely newer and better ASICs to support new features in the future, smaller high-end power supplies. It is also a bit less noisy and has front-to-back or back-to-front air flow (instead of side-to-back in the 4200) which will allow the switch to fit better in hot/cold separated environments.

    Hi

    Please read:

    About Limited lifetime Warranty.

     

    Another difference between 4200 and 4300 is new FULL-MESH architecture in VC (5 equipments in VC ). And more power (buffers, performance, ...).

     

    Also I think that perhaps 4300 can't VC to 4500. (not confirmated)

     

    Also you can read this entry: http://forums.juniper.net/t5/The-New-Network/The-EX4300-An-Enterprise-switch-you-can-bet-on/ba-p/201473

     

    Bye!

    The 4300 cannot VC to the 4500. They are built with different chipsets and they are incompatible.

    As others have said, the EX4300 can't VC to any of the existing 4xx0 series, primarily because it uses the 40G ports to do so, but also due to architecture differences.

     

    If I was in the Juniper product naming meeting, I probably would have suggested calling this the EX5x00, since they've just confused the entire issue of being able to VC 2x00, 3x00 or 4xx0 families together.

    Thanks for sharing the info!

    There are also some other differences which are not as obvious:

    ---snip---

    MACsec is currently supported on the following EX Series switch interfaces:

    • The uplink port connections on the SFP+ MACsec uplink module that can be installed on EX4200 series switches.
    • All access and uplink ports on EX4300 switches.

    As said the EX4300 can not VC to "legacy" EX4xxxes but instead it can be bound to a VC fabric or a mixed VC with QFX3500 or QFX5100.

    There is also a more or less big difference in the junos cli of the ex4300.

    http://www.juniper.net/techpubs/en_US/junos13.2/topics/task/configuration/getting-started-els.html#jd0e315

    Juniper calls it the enhanced layer 2 software.

    One big advantage of that new structure for example is that you now are able to configure several storm-control profiles and activate them on different interface ranges or single interfaces on the interface level instead of having to configure storm control for every interface range again in the ethernet-switching-options tree. So you can also simply make an apply-group for access ports, assign the storm-control profile and just assign this apply-group to the interfaces you want. It is saving a lot of keyboardwork and possibily saves you from forgetting this Smiley Wink

     

    What might also of big difference/advantage over the EX4200 is the front-to-back and back-to-front airflow options. The EX4200 has only air inlets on each side of the chassis and the outlet at the rear - which is a problem in ToR deployments.
