Updating ios via xmodem
However I came across something today, that I have known about for a while but never really used much.One of the things every one seems to love about CISCO is the fact you can simple copy and past configurations in to the terminal emulator window. set up one interface, copy the config to notepad, update it as you wish and past it back in…With a little trial and error, I found that the maximum baud rate I could set it up to work perfectly with was 57600. You can set the baud rate in ROMMON using the set BAUD Begin the Xmodem or Xmodem-1K transfer now…C……………………………………………………………………. I could see that while things like VLAN’s where being created and the device was pausing, the following lines would some times get lost or corrupted.
To fix this, I have to reinstall the IOS but since the normal procedure would no longer work, I will do it using ROMMON. First, power-off the switch by unplugging the power cable, press and hold the MODE button, power on the switch by plugging the power cable.
So then it is just a case of knowing the command to achieve the goal, and I was happy to see it is as simple as it should be.
On the device simple type the following from the enable prompt.
Since then I cannot get any image to boot and cannot install a new one despite many attempts with XMODEM.
Since the device is in ROMMON, there’s not much that you can do.

What I really wanted was a way to send the configuration file through the console port.
