how to boot cisco switch from Rommon using tftp?
Posted on 2008-06-17
I have a cisco switch with a bad IOS image, it would only boot to rommon. I formatted the flash and tried using xmodem to copy the new image to flash. After a couple failures, I realized that the ONLY images that Cisco offers for this device only are TOO BIG for the flash for some reason?
Is there a way to boot the image from a tftp server while in Rommon mode? I have typed in the following:
set IP_ADDRESS 172.16.2.251
set IP_SUBNET_MASK 255.255.255.0
set DEFAULT_GATEWAY 172.16.2.254
set TFTP_FILE c2900xl-c3h2s-mz.120-5.WC17.bin
set TFTP_SERVER 172.16.2.1
I then type boot and it always says boot process failed.
Is it possible to boot the image from Rommon via TFTP, if so what am I doing wrong?
