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.
Examples
# Enable IRF auto-merge.
<Sysname> system-view
[Sysname] irf auto-merge enable
irf auto-update enable
Use irf auto-update enable to enable the software auto-update feature.
Use undo irf auto-update enable to disable the software auto-update feature.
Syntax
irf auto-update enable
undo irf auto-update enable
Default
The software auto-update feature is enabled.

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
# Enable the software auto-update feature.

[Sysname] irf auto-update enable
irf domain
Use irf domain to specify an IRF MAD domain ID.
Use undo irf domain to restore the default.
Syntax
irf domain domain-id
undo irf domain
Default
The IRF MAD domain ID is 0.
Views
System view
Predefined user roles
network-admin
Parameters
domain-id: Specifies an IRF MAD domain ID. The value range is 0 to 4294967295.
Usage guidelines
An IRF MAD domain ID uniquely identifies an IRF multi-active detection domain. If the IRF fabric
uses another IRF fabric as the intermediate device for LACPMAD, ARPMAD, or ND MAD, you must
assign the two IRF fabrics different MAD domain IDs for correct split detection. False detection
causes IRF split.
An IRF fabric has only one IRF MAD domain ID. You can change the IRF MAD domain ID by using
the irf domain, mad enable, mad arp enable, or mad nd enable command. The IRF MAD domain
IDs configured by using the commands overwrite each other.
Example
# Set the IRF MAD domain ID to 10.
<Sysname> system-view
[Sysname] irf domain 10
irf mac-address persistent
Use irf mac-address persistent to configure IRF bridge MAC persistence.
Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as
soon as the address owner leaves.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent
Default
The IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves the
IRF fabric.
Views

Predefined user roles
network-admin
Parameters
always: Enables the IRF bridge MAC address to be permanent. The IRF bridge MAC address does
not change after the address owner leaves.
timer: Enables the IRF bridge MAC address to remain unchanged for 6 minutes after the address
owner leaves. If the owner rejoins the IRF fabric within the time limit, the IRF bridge MAC address
does not change. If the owner does not rejoin within the time limit, the IRF fabric uses the bridge
MAC address of the current master as the bridge MAC address.
Usage guidelines
IRF bridge MAC persistence specifies the amount of time an IRF fabric can continue using a bridge
MAC address as its bridge MAC address after the address owner leaves.
By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC
address. Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On
a switched LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address
automatically after the address owner leaves. However, the change causes temporary service
disruption. Depending on the network condition, you can enable the IRF fabric to retain or change its
bridge MAC address after the address owner leaves.
If ARP MAD or ND MAD is used, you must disable IRF bridge MAC persistence by using the undo irf
mac-address persistent command.
When IRF fabrics merge, IRF ignores the IRF bridge MAC address and checks the bridge MAC
address of each member device in the IRF fabrics. IRF merge fails if any two member devices have
the same bridge MAC address.
Examples
# Enable the IRF bridge MAC address to be permanent.
<Sysname> system-view
[Sysname] irf mac-address persistent always
irf member description
Use irf member description to configure a description for an IRF member device.
Use undo irf member description to restore the default.

CAUTION:
An IRF member ID change can invalidate member ID-related settings, including interface and file
path settings, and cause data loss. Make sure you fully understand its impact on your live network.
Make sure each member device in the IRF fabric has a unique member ID.
The new IRF member ID, including the one set by using the undo irf member renumber command,
takes effect after you reboot the member device.
To cancel the change before you reboot the member device, use the undo irf member renumber
command. In the command, set the new member ID to be the same as the old member ID.

Usage guidelines
After you bind links to an IRF port, you must execute this command for the bindings to take effect.
This command enables two devices to merge into one IRF fabric.
The system activates the IRF port settings automatically in the following situations:
•The configuration file that the device starts with contains IRF port bindings.
•You are binding links to an IRF port after an IRF fabric is formed.
Examples
To configure and activate IRF-port 1:
# Bind GigabitEthernet 1/0/1 to IRF-port 1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
