Hello, I have forgetten my password for my test cisco 2950 switch.  I am trying to get the switch into rommon mode so that I can carry out the steps to reset the password.   When I reload the switch and press the crtl break the switch doesnt go into rommon mode and gives the following output -

The system has been interrupted prior to initializing the
flash filesystem.  The following commands will initialize
the flash filesystem, and finish loading the operating
system software:

    flash_init
    load_helper
    boot

switch:

Any Ideas anyone ?

no-no this is a normal startup, you have to interrupt boot process with ctrl+brake
I would suggest using putty or secure crt, because they can pass ctrl+brake sequence to the switch.
