Most realize once after applying the latest update and rebooted, the switch no longer responds and the management interface cannot be accessed. This is because you will need to first apply the boot firmware before you can apply the OS. At this point, you have no choice but to access and restore the switch via the console port. Not your regular console cable If you read the official documentation for the switch, the console cable specified is a “null modem” serial cable. This is WRONG! You will need a “straight through” or “modem” serial cable.

The difference between the two is that the null modem cable has the pins 2-3 ie. RX & TX flipped, where as for the straight through cable all pins are 1 to 1. Finding this cable can be difficult. So a clever way to construct one is to use two cisco console cables and an inline Rj45 coupler as shown below.

Once you have the cable follow the below steps to recover. How to recover • First download the old firmware “ runtop-10086.ros“. You should be able to find this via some simple googling • Go download.

This version of putty gives you the needed xmodem transfer function in your next steps • Connect your console cable to the switch using baud rate 38400, 8-N-1. • Power on the switch and you should get the following output BOOT Software Version 1.0.0.03 Built 08-Jun-2004 09:48:10 CPU - FireFox 88E6218 ARM946E-S processor 64 MByte SDRAM.

A very good evening to all! There are times when the IOS on a switch may crash and (as a last resort) you need to use the painfully slow Xmodem transfer to save your life. I bought a 3550 a while back and that is precisely what happened with me.

Without much else to try, I decided to give Xmodem a shot. I want to share how this can be used and I hope that this may be useful to others. Since the device is in ROMMON, there’s not much that you can do. There is, however, a method to transfer another IOS using a direct console connection with a PC (the transfer is over your console cable itself). This wonderful little thing is called Xmodem.

Now the rate of transfer depends on the baud rate that you set for your console connection. I tried this with baud set to 9600 and man, it seemed like it would take over 3 hours for the transfer to complete. 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 command. See below: switch: set BAUD 57600 This MUST also match on the terminal program setting as well. So (I’m using TeraTerm) under Setup -> Serial Port, set the baud rate to match whatever you set it as in ROMMON. Now we’re ready to transfer the file.

The command is very straight forward: switch: copy xmodem: flash:c3550-ipservicesk9-mz.122-44.SE6.bin Once you press enter, you see the following: Begin the Xmodem or Xmodem-1K transfer now C At this point, you need to choose the file location from the terminal program. Go under File -> Transfer -> Xmodem -> Send and choose the file that you wish the transfer. The transfer will start and you will see a transfer window pop up like this: Once completed, you should get a prompt back to your ROMMON: Begin the Xmodem or Xmodem-1K transfer now C............... File “xmodem:” successfully copied to “flash:c3550-ipservicesk9-mz.122-44.SE6.bin” Now from ROMMON, boot from flash using the following command: switch: boot flash:c3550-ipservicesk9-mz.122-44.SE6.bin This will try to boot the IOS specified and if the transfer was good, then this should go smoothly. This is the best, most straightforward post about reinstalling your ios with xmodem. I was fixing my 3560 and this did it for me! I only had trouble with changing baud rate.
