![]() ![]() Opened putty options and changed baud from 9600 to 115200īegin the xmodem or xmodem-1k transfer nowĪfter 10 mins no 'i/o error ' showing but no cccccccc. I have now reset switch and done the following using 'pumpkin' Yes ive followed youtube instructions for:Īccesses putty options and changed baud from 9600 to 115200Ĭopy xmodem: flash:c3550-i5q312-mz.121- 22.EA2.binĬopy xmodem: flash:c3550-i5q3l1-mz.121- 22.EA2.bin - the (312 looks like 3l2) but i have tried both and it appears to be (i5q312 not i5q3l1) Note: I have been looking at the below sites: ![]() as I am not using win 2003 that uses 'hyperterminal', I am now using win 2008 that does not use 'hyperterminal', so can anyone advise on how to copy the ios from my tftp back to my cisco 3550 ? I then change '11500 back to 9600' and I can view the 'putty' screen as usual If I access the 'putty' properties and change baud rate from '9600 to 11500' the putty screen cursor shows, but when I hit enter, the screen does not show any characters. Reloaded 3550 by pressing the 'mode' button on the switch which is now showing the prompt below and I have typed the below: This will send the file to ttyUSB0 over xmodem protocol. Then press Ctrl-A followed by : and type: exec sx yourbinary.bin. In debian: apt-get install screen lrzsz screen /dev/ttyUSB0 115200. In debian this application is part of lrzsz package. Just to make sure no corruption, I have installed 'tftp - putty' and copied the ios into the putty path as usual the best way to pass a file through xmodem is to use sx. Hi I am currently using a 3550 layer 3 switch. ![]()
