11
This command is available in IRF mode. When the operating mode is changed to standalone, the
configuration of this command is lost, regardless of whether you have saved the configuration.
The IRF auto merge function takes effect for an IRF merge that occurs when the IRF link recovers from a link
failure, or when you connect the IRF physical ports of the member devices. It does not take effect for the
IRF merge that occurs when you bind a physical port to an IRF port in IRF mode.

Usage guidelines
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.
To join an IRF fabric, a device must use the same software images as the master in the IRF fabric.
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 performs the following tasks automatically:
1. Downloads the current software images of the master.
2. Sets the downloaded images as its main startup software images.
3. Reboots with the new software images to rejoin the IRF fabric.
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.
Before you use the software auto-update function, verify the following items:
• The device you are adding to the IRF fabric is compatible with the software version running on the
master. If it is not compatible, the automatic software upgrading function cannot work.
