Preparing for the upgrade
Use the display version command to verify the current Boot ROM image version and startup software version.
Use the release notes for the upgrade software version to evaluate the upgrade impact on your network and verify the following items:
Software and hardware compatibility.
Version and size of the upgrade software.
Compatibility of the upgrade software with the current Boot ROM image and startup software image.
Use the dir command to verify that all IRF member devices have sufficient storage space for the upgrade images. If the storage space is not sufficient, delete unused files by using the delete command. For more information, see "Managing the file system."
Configure FTP or TFTP settings.
Use FTP or TFTP to transfer the upgrade image file to the root directory of a storage medium on the IRF fabric.
For more information about FTP and TFTP, see "Configuring FTP" and "Configuring TFTP."
