IOS Recovery of 3750 switch

I had a corrupted IOS image on a 3750E switch today and feared for a xmodem transfer to eat up my day, until I found that you can copy from TFTP. It’s very well hidden, but still possible. Here’s how:

When the switch has ‘booted’ without a proper IOS, you’ll be in the ‘switch: ‘ command line. In the following example, I will assume that the TFTP server has IP 192.168.0.10 and the switch will use 192.168.0.1.

Connect your TFTP server to the ethernet management port, then follow this sequence:

switch: set IP_ADDR 192.168.0.1/255.255.255.0

switch: set DEFAULT_ROUTER 192.168.0.10

switch: copy tftp://192.168.0.10/IOS_image_file_name.bin flash:IOS_image_file_name.bin

switch: set BOOT flash:IOS_image_file_name.bin

switch: boot
