To display the available file systems on your device, use the show file systems privileged EXEC command as shown in this example for a standalone device: Only one user at a time can manage the software bundles and configuration files for a device stack. Use the show file systems privileged EXEC command to list all file systems, including the flash file systems in the device stack. For example, flash-3:, as viewed from the active device, refers to the same file system as does flash: on stack member 3. The names of these flash file systems include the corresponding device member numbers. In a device stack, each of the flash devices from the various stack members can be viewed from the active device. TheĪs viewed from the active device, or any stack member, flash: refers to the local flash device, which is the device attached to the same device on which the file system is being viewed.

I ended up using a 128GB SanDisk Cruzer USB drive that I had in my bag, and I downloaded & copied the appropriate. I was able to recover these using a USB thumb drive and following the Cisco 3850 Recovery Techniques documentation (see source references at the bottom of this post for links)ġ) First I needed a USB flash drive onto which I could store a copy of known working code version, so that I could boot the switch off the USB, and later copy the image from the USB to the switch's internal flash. Some of the switches were seemingly bricked from bad code, while others were stuck at the ROMMON switch: prompt, and others still cycling in a (re)boot loop. Recently I have had to recover different Cisco Catalyst 3850 switches due to failed software installs or failed auto-upgrades in the stack, or unintentionally installing the wrong code on the wrong switch model, or having corrupted or missing nf directory files :-/
