Irf Domain - HPE FlexFabric 7900 series Command Reference Manual

To ensure a successful software update, verify that the new MPU you are adding to the IRF fabric
has sufficient storage space for the new software images. If sufficient storage space is not available,
the MPU deletes the current software images automatically. If the reclaimed space is still insufficient,
the MPU cannot complete the auto-update. You must reboot the device that holds the MPU, and
then access the BootWare menus to delete files.
You must manually update the new MPU 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 MPU.
Examples
# Enable the software auto-update feature.

[Sysname] irf auto-update enable

Parameters
domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
This command is available in IRF mode. When you change the operating mode from IRF to
standalone, the IRF domain setting is lost, regardless of whether you have saved the configuration.
One IRF fabric forms one IRF domain. IRF uses IRF domain IDs to uniquely identify IRF fabrics and
prevent IRF fabrics from interfering with one another.
If one IRF fabric uses another IRF fabric as the intermediate device for LACP MAD or BFD MAD,
you must assign the two IRF fabrics different domain IDs for correct split detection. False detection
causes IRF split.
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the irf
domain or mad enable command. The IRF domain IDs configured by using these commands
overwrite each other.
In an MDC environment, the irf domain command is available only on the default MDC. The mad
enable command is available on all MDCs. If you change the IRF domain ID in one MDC, the IRF
domain IDs in all other MDCs change automatically.
