    Hi I have a 2950. Show Version shows the conf-reg as 0xF which I guess is the default for this model. The thing is I can't change that value. I am trying to copy my IOS to my pc via the console cable. I'm guessing to do this you have to be in ROMMON mode. If I go into global mode and use the command: config-register 0x2100 it says invalid input detected! It doesn't accept any changes to the config-register. How can I change, and secondly how can I copy the IOS from flash to my pc via console? Thanks.

    Here is my show version output:

    config register comand is supported only in routers not in switches.
