I accidentally deleted some of the startup images from the flash on a Cisco Catalyst 3650. I am going through the steps of transferring a new ios image using a serial cable and extraputty, however when I get to the transfer portion, the switch begins the transfer and immediately self aborts.
I still have some files showing in the flash directory, I thought maybe I need to clear the rest of these so tried the format flash: command, however i get the "invalid argument" response.
I also tried to create a specific flash directory for the image and it gives me a directory not created, read only file system.
What am I doing wrong here? Pulling my hair out due to a stupid mistake
is this old 3650 or white 3650 new once ? and post output of
switch: dir flash:
or try emergency recovery :
Thanks for your reply. I was able to use a USB to boot from and then transfer the bootable image to the devices internal flash storage and recover the system.
The switch was a dark gray Catalyst 3650.
Incase anyone is looking here in the future, I followed this guide:
PuTTY or your extraputty skin for PuTTY may not be able to sustain the connection as long as you need for Xmodem transfer. I had the same issue when using Teraterm, and no matter what the connection cut out. I then downloaded a free trial of SecureCRT, and that program was able to complete the transfer without becoming disconnected.
