Usage guidelines
IRF fabrics that are merging perform master election. The IRF auto-merge feature enables the
member device in the IRF fabric that fails the master election to automatically reboot for completing
the IRF merge. If the IRF auto-merge feature is disabled, you must follow the system instructions to
manually reboot the member device in the IRF fabric that fails the master election.
For a successful merge, make sure IRF auto-merge is enabled on both IRF fabrics that are merging.
For example, IRF auto-merge takes effect on merges caused by the following events:
•
The IRF link recovers from a link failure.
•
The IRF network interfaces of the member devices are connected through a Layer 2 network
after the interfaces are bound to IRF ports.

Usage guidelines
This command automatically propagates the current software images of the master in the IRF fabric
to member devices you are adding to the IRF fabric.
To ensure a successful software update, verify that the new device you are adding to the IRF fabric
has sufficient storage space for the new software images. If sufficient storage space is not available,
the device automatically deletes the current software images. If the reclaimed space is still
insufficient, the device cannot complete the auto-update. You must reboot the device, and then
access the Boot ROM menu to delete files.
You must manually update the new device with the software images running on the IRF fabric in the
following situations:
•
Software auto-update is disabled.
•
Software auto-update fails to update software. This situation might occur if the IRF fabric cannot
identify the software version used on the new device.
Examples
