Usage guidelines
To join an IRF fabric, a device must use the same set of software images as the master in the fabric.
The software auto-update function automatically synchronizes the current software images of the
master in an IRF fabric to all its members.
Before enabling software auto-update, make sure the device you are adding to the IRF fabric has
sufficient storage space for the new software images.
If no sufficient storage space is available, the device automatically deletes the current software
images. If the reclaimed space is still insufficient, the device cannot complete the auto-update, and
you must reboot the device and access the Boot menu to delete some files.
When you add a device to the IRF fabric, the software auto-update function compares the startup
software images of the joining device with the current software images of the IRF master. If the two
sets of images are different, the device automatically downloads the current software images of the
master, sets the downloaded images as its main startup software images, and automatically reboots
with the new software images to rejoin the IRF fabric.
If the device 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. For more information about
the software version, see the release note for that version.
When the master is propagating its software images to the member devices, do not remove or
reboot the active MPU of each member device, and make sure the IRF links between each pair of
member devices are all in up state.
If software auto-update is disabled, you must manually update the device with the software images
of the master before adding it to the IRF fabric.
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the irf auto-update enable command configuration, even if you have saved the
configuration.
