You can configure your Cisco NX-OS device by using configuration files that you created on another Cisco NX-OS device and uploaded to a remote server. You then download the file from the remote server to your device using TFTP, FTP, Secure Copy (SCP), or Secure Shell FTP (SFTP) to the running configuration.
Before You Begin
Ensure that the configuration file that you want to download is in the correct directory on the remote server.
Ensure that the permissions on the file are set correctly. Permissions on the file should be set to world-read.
Ensure that your Cisco NX-OS device has a route to the remote server. The Cisco NX-OS device and the remote server must be in the same subnetwork if you do not have a router or a default gateway to route traffic between subnets.
Check connectivity to the remote server using the ping or ping6 command.
