Usage guidelines
To join an IRF fabric, a device must use the same software images as the master in the IRF fabric. The
software auto-update function propagates the current software images of the master in an IRF fabric to all
its members automatically. 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.
When you add a device to the IRF fabric, software auto-update compares the startup software images of
the 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 main startup software images.
3.
Reboots with the new software images to rejoin the IRF fabric.
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 sufficient storage space is not available, the device deletes the current software images automatically.
If the reclaimed space is still insufficient, the device cannot complete the auto-update. You must reboot the
device and access the Boot menu to delete files.
To ensure a successful software auto-update in a multi-user environment, prevent the action of rebooting
member devices during the auto-update process. You can configure the information center to output the
software auto-update status to configuration terminals (see
Network Management and Monitoring
Configuration Guide
).
