Enabling Auto Upgrade of Boot Files
If auto upgrade of boot files is disabled, when the boot files of slaves and the boot file of the master are
in different versions, the new member or the member with a low priority will not boot normally. You need
to manually update the device version and add the device into the IRF virtual device again.
If auto upgrade of boot files is enabled, as soon as a device is added into an IRF virtual device, the IRF
virtual device compares its software version with that of the master. If the versions are not consistent,
the device automatically downloads the boot file from the master, reboots with the new boot file, and
joins the IRF virtual device again. If the downloaded boot file and the local file have duplicate file names,
the local file is overwritten.
Follow these steps to enable auto upgrade of boot files for an IRF virtual device:

z
Although an IRF virtual device supports the auto upgrade of boot files, you are recommended to
ensure that a new device and the master have the same software version before adding the into
the IRF virtual device, thus to shorten the time for IRF virtual device establishment and reduce the
influences caused by IRF virtual device establishment to the network,
z
After automatically loading the master’s boot file, a slave configures the file as the boot file to be
used at the next boot and reboots automatically.
z
To make the auto upgrade succeed, ensure that there is enough space on the storage media of
slaves because system boot file occupies large memory space.
Setting the Delay Time for the Link Layer to Report a Link-Down Event
After you set the delay time for the link layer to report a link-down event:
z
If the IRF link state changes from up to down, the port does not immediately report the link state
changes to the system. After the configured time interval, if the IRF link state is still down, the port
reports the link state changes to the system, and then the system handles the problem
accordingly.
z
If the link state changes from down to up, the link layer immediately reports the event to the
system.
