Usage guidelines
When you add a switch to the IRF fabric, the software auto-update function compares the system software
versions of the switch and the IRF master. If the versions are different, the switch automatically downloads
the system software image from the master, sets the downloaded file as the system software for the next
reboot, and automatically reboots with the new system software image to re-join the IRF fabric.
To avoid an update failure, make sure the switch has efficient space for the new system software image.
If the switch you are adding to the IRF fabric is incompatible with the software version running on the
master, the software auto-update function cannot work correctly.
If software auto-update function is disabled, you must manually update the switch with the system
software image of the master.
