Copying Files in a Cisco Nexus 9000 Switch

Here's a Cisco link in copying or transferring a Nexus config file to a remove server (or local USB). This is useful if you're doing an RMA and needed to quickly transfer config from old to new Nexus switch. If you're using the USB flash drive/disk, make sure it's formatted to FAT16

 

N9K# copy running-config usb1:my-config.cfg

Copy complete, now saving to disk (please wait)...

Copy complete.

 

 

N9K# dir usb1:

       4096    Feb 06 09:41:48 2026  System Volume Information/

      34494    Feb 06 09:41:48 2026  autorun.ico

The NX-OS file transfer took a few minutes to finish. Make sure your USB drive has enough memory.

N9K# copy nxos64-cs.10.x.M.bin usb1:nxos64-cs.10.x.M.bin
