Highest IOS Version for Cisco WS-C2950G-24-EI Switch

Posted on 2011-04-28

We have a Cisco WS-C2950G-24-EI switch that we would like to use.  It is currently running IOS Version 12.1(9)EA1.  I would like to upgrade this.  On the Cisco download site, it says the current IOS for this model is 12.1-22.EA14.  Does this mean that I can’t upgrade it to Version 12.2(25)SEE2, which is the version the rest of our switches are running.  The rest of our switches are C2960 and above.

Also, can I copy the config file from one switch to another if the IOS versions are different?

    You can't run the 2960 IOS on 2950's.

    I wouldn't copy the startup config but paste  the config in line by line so it will tell you what commands are not compatible with the 2950 (only some 2960 new features, but nothing important as far as I know).

    these are basic Layer 2 devices.

    The Cisco WS-C2950G-24-EI Switch is end of life ( and it appears that the 12.1.22-EA14 IOS release, is the best you can get.

    It is never a good idea to use the wrong IOS. Would it be better replace the Cisco WS-C2950G-24-EI Switch  with a 2960?

    Koudry, Do you mean it is a bad idea to have a switch on the network with a different IOS, or a bad idea to use an IOS that is not the current recommened IOS for that switch?

    I am saying that it is a bad idea to use IOS that is not designed for that device/platform. This may be technically doable but I don't know if this will work very well.
