- In the privilage mode Use the
dircommand to view the contents of the USB flash drive and verify that the IOS image file is present
- Copy the IOS Image File:
- Use the

- After the switch restarts, it's essential to verify that it's running the updated IOS version. You can do this using the
show versioncommand. Here's how you can verify the IOS version after the switch restarts:
- This command provides detailed information about the switch, including the IOS version currently running. Look for the "System image file" or "IOS Software" section in the output, which indicates the IOS version.
- After running this command, ensure that the displayed IOS version matches the version you intended to upgrade to. If the version matches, it confirms that the switch successfully booted using the updated IOS image.
