Parameters
None
Description
Use the irf auto-update enable command to automatically synchronize the boot file of the master switch
to the switch you are adding to the IRF virtual device.
Use the undo irf auto-update enable command to disable this function.
By default, this function is enabled.
When you add a switch to the IRF virtual device, the automatic boot file updating function compares the
software versions of the switch and the IRF master. If the versions are different, the switch automatically
downloads the boot file from the master, sets the downloaded file as the boot file for the next reboot, and
automatically reboots with the new boot file to re-join the IRF virtual device.
If this function is disabled, you must manually ensure that the joining switch uses the same boot file as the
master switch. If not, the new switch cannot join the IRF virtual device.
IMPORTANT:
• Check that the switch has efficient space for the new boot file.
• If the switch has a boot file that uses the same name as the new boot file, back up the old boot file as
needed. The downloaded new boot file will overwrite the old boot file.
