Uploading Upgrade Files Using SFTP

For a seamless upgrade process, we recommend using the Secure File Transfer Protocol (SFTP) to copy the necessary files to your Nexus switch. To facilitate this, you can use a utility like “freeFTPd” to set up a quick and efficient SFTP server.

Once you have your SFTP server ready, files can be effortlessly copied to the switch using the following command:

copy sftp://<username>:<password>/<path_to_upgrade_file> bootflash:

Performing the Upgrade

With the files securely transferred to your Nexus switch, it’s time to proceed with the installation. Below are the essential commands to execute the upgrade:

1. Show the Impact of the Update

Before initiating the installation, it’s wise to assess the impact of the update. This helps you anticipate any potential challenges. Run the following command, replacing with the name of your upgrade file:

show install all impact nxos bootflash:<filename>

2. Perform the Installation

Once you’ve reviewed the impact and are ready to proceed, execute the installation using the following command:

install all nxos bootflash:<filename>
