Syntax
irf auto-update enable
undo irf auto-update enable
Default
The software auto-update function is enabled.
Views
System view
Predefined user roles
network-admin
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 automatically propagates the current software images of the master in an
IRF fabric to all its members. 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, 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:
•Downloads the current software images of the master.
•Sets the downloaded images as its main startup software images.
•Reboots with the new software images to rejoin the IRF fabric.

9
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 automatically deletes the current software images.
If the reclaimed space is still insufficient, the device cannot complete the auto-update, and you must
reboot the device and access the BootWare menus to delete files.
To ensure a successful software auto-update in a multi-user environment, prevent the action of rebooting
member devices during the software 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).
Examples
# Enable the software auto-update function.
<Sysname> system-view
[Sysname] irf auto-update enable
irf domain
Use irf domain to assign a domain ID to the IRF fabric.
Use undo irf domain to restore the default IRF domain setting.
Syntax
irf domain domain-id
undo irf domain
Default
IRF domain ID is 0.
Views
Any view
Predefined user roles
network-admin
Parameters
domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
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 you use one IRF fabric as the intermediate device for LACP MAD, ARP MAD, or ND MAD for another
IRF fabric, 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 with the following
commands: irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domain IDs
configured by using these commands overwrite each other.
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view

10
[Sysname] irf domain 10
irf link-delay
Use irf link-delay to set a delay for the IRF ports to report a link down event.
Use undo irf link-delay to restore the default.
Syntax
irf link-delay interval
undo irf link-delay
Default
The IRF link down event report delay is 4 seconds.
Views
System view
Predefined user roles
network-admin
Parameters
interval: Sets the IRF link down report delay in the range of 0 to 10000 milliseconds. If the interval is set
to 0, link down events are reported without any delay.
Usage guidelines
An IRF link down report delay helps avoid link flapping. Link flapping causes frequent IRF splits and
merges during a short time.
An IRF port handles link down and link up events as follows:
•When the IRF link changes from up to down, the port does not immediately report the change to the
IRF fabric. If the IRF link state is still down when the delay time is reached, the port reports the
change to the IRF fabric.
•When the IRF link changes from down to up, the link layer immediately reports the event to the IRF
fabric.
HP recommends setting the delay to 0 seconds in one of the following situation:
•The IRF fabric requires a fast master/subordinate or IRF link switchover.
•The BFD or GR feature is used.
If the CFD feature is used in the IRF fabric, make sure the delay interval is smaller than the maximum CCM
lifetime. For more information about CFD, see High Availability Configuration Guide.
Examples
# Set the IRF link down report delay to 300 milliseconds.
<Sysname> system-view
[Sysname] irf link-delay 300
irf mac-address persistent
Use irf mac-address persistent to configure IRF bridge MAC persistence.

11
Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as soon
as the master leaves.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent
Default
After the master device leaves, the IRF fabric continues using its bridge MAC address as the IRF bridge
MAC address for 6 minutes. If the device does not rejoin the IRF fabric before that time limit is reached,
the IRF fabric uses the bridge MAC address of the new master as the IRF bridge MAC address.
Views
System view
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 master re-election.
timer: Enables the IRF bridge MAC address to remain the same for 6 minutes after the master device
leaves. If the device rejoins the IRF fabric before the time limit is reached, the IRF bridge MAC address
does not change. If not, the IRF fabric uses the bridge MAC address of the new master as the IRF bridge
MAC address.
Usage guidelines
IRF bridge MAC persistence specifies the amount of time an IRF fabric can continue using the old master
bridge MAC address as its bridge MAC address after a master re-election.
If ARP MAD or ND MAD is used, execute the undo irf mac-address persistent command to enable
immediate bridge MAC address change after the master leaves.
Configure the irf mac-address persistent always command in one of the following situations:
•TRILL is configured.
•The IRF fabric uses a daisy-chained topology, and it has aggregate links with upstream or
downstream devices. The setting prevents a bridge MAC change from causing transmission delay
or packet loss at a master/subordinate switchover.
An IRF fabric by default 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 its master leaves. However, the change causes temporary service disruption.
Depending on your network condition, you can enable the IRF fabric to preserve or change its bridge
MAC address after the master leaves.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
Examples
# Enable the IRF bridge MAC address to be permanent.
<Sysname> system-view
[Sysname] irf mac-address persistent always

Parameters
member-id: Specifies the ID of an IRF member, in the range of 1 to 10.
new-member-id: Assigns a new ID to the IRF member, in the range of 1 to 10.
Usage guidelines
CAUTION:
Changing the IRF member ID of a device can cause losses of member ID-related confi
g
urations, includin
g
settings on physical ports, at reboot.
To have the new ID take effect, you must reboot the IRF member.
When adding a device into an IRF fabric, you must assign a unique IRF member ID to the device. If its IRF
member ID has been used in the IRF fabric, the device cannot join the IRF fabric.

14
Plan your IRF member ID assignment before setting up an IRF fabric, and change member IDs before
making any other configuration.
Interchanging member IDs between IRF member devices might cause undesirable configuration changes
and data loss. For example, the IRF member IDs of Device A and Device B are 2 and 3. After you
interchange their member IDs, their port settings also interchange.
After an IRF fabric is formed, make sure you understand the impact of the member ID change on your
network.
Examples
# Change the ID of an IRF member from 1 to 3.
<Sysname> display irf
[Sysname] irf member 1 renumber 3
Warning: Renumbering the member ID may result in configuration change or loss.

Parameters
member-id/port-number: Specifies an IRF port on an IRF member. The member-id argument represents
the ID of the IRF member. The port-number argument represents the IRF port index and must be 1 or 2.
Usage guidelines
To set up an IRF link between two devices, you must enter IRF port view to bind physical ports to the IRF
port used by each device for IRF connection.
Before you remove all port bindings of an IRF port, shut down all its physical ports.
Examples
# Bind Ten-GigabitEthernet 3/0/17 to IRF port 3/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/17
[Sysname-Ten-GigabitEthernet3/0/17] shutdown
[Sysname-Ten-GigabitEthernet3/0/17] quit
[Sysname] irf-port 3/1
[Sysname-irf-port3/1] port group interface ten-gigabitethernet 3/0/17

irf-port global load-sharing mode
Use irf-port global load-sharing mode to set the global load sharing mode for IRF links.
Use undo irf-port global load-sharing mode to restore the default.
Syntax
irf-port global load-sharing mode { destination-ip | destination-mac |source-ip |source-mac } *
undo irf-port global load-sharing mode
Default
Packets are automatically distributed across IRF member links based on their packet types.

Parameters
destination-ip: Distributes traffic across IRF member links based on destination IP address.
destination-mac: Distributes packets across IRF member links based on destination MAC address.
source-ip: Distributes packets across IRF member links based on source IP address.
source-mac: Distributes packets across IRF member links based on source MAC address.
Usage guidelines
The global IRF link load sharing mode applies to all IRF ports in the IRF fabric. You can configure the
global IRF link load sharing mode to include a combination of multiple criteria for making traffic
distribution decisions. For example, criteria could include source MAC address and IP address. If your
device does not support a criterion combination, the system displays an error message.
If you configure the global load sharing mode multiple times, the most recent configuration takes effect.
You can also configure a port-specific load sharing mode for an IRF port in IRF port view.
An IRF port preferentially uses the port-specific load sharing mode. If no port-specific load sharing mode
is available, it uses the global load sharing mode.
Examples
# Configure the global IRF link load sharing mode to distribute traffic based on destination MAC
address.
<Sysname> system-view
[Sysname] irf-port global load-sharing mode destination-mac

Parameters
destination-ip: Distributes traffic across IRF member links based on destination IP address.
destination-mac: Distributes packets across IRF member links based on destination MAC address.
source-ip: Distributes packets across IRF member links based on source IP address.
source-mac: Distributes packets across IRF member links based on source MAC address.
Usage guidelines
To successfully configure a port-specific load sharing mode for an IRF port, make sure you have bound
at least one physical port to the IRF port.
You can configure an IRF port-specific load sharing mode to include a combination of multiple criteria for
making traffic distribution decisions. For example, criteria could include source MAC address and IP
address. If your device does not support a criterion combination, the system displays an error message.
If you configure the port-specific load sharing mode multiple times on an IRF port, the most recent
configuration takes effect.
An IRF port preferentially uses the port-specific load sharing mode. If no port-specific load sharing mode
is available, it uses the global load sharing mode.
Examples
# Configure a port-specific load sharing mode for IRF port 1/1 to distribute traffic based on destination
MAC address.

Usage guidelines
After connecting the physical ports between two devices and binding them to the correct IRF ports, you
must use this command to activate the settings on the IRF ports to merge the two devices into one IRF
fabric.
Activating IRF port settings can cause an IRF merge and device reboot. To avoid configuration loss, use
the following procedure to set up your IRF fabric:
1. Plan the IRF setup, including the IRF fabric topology, IRF fabric size, member ID assignment, and
bindings of physical ports and IRF ports.
2. Change the IRF member ID of each device to make sure they are unique in the IRF fabric.
3. Connect the physical ports between neighboring devices and make sure the peer ports can reach
each other.
4. Bind the physical ports to the IRF ports on each device.
5. Save the configuration to the startup configuration file on each device.
6. Activate the IRF ports on each device.
The system automatically activates the IRF port settings in the following situations:
•The configuration file that the device starts with contains IRF port bindings.
•You are binding physical ports to an IRF port after an IRF fabric is formed.
Examples
To configure and activate IRF port 1/2:
# Bind Ten-GigabitEthernet 1/0/17 to IRF-port 1/2.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/17
[Sysname-Ten-GigabitEthernet1/0/17] shutdown
[Sysname-Ten-GigabitEthernet1/0/17] quit
[Sysname] irf-port 1/2
[Sysname-irf-port1/2] port group interface Ten-GigabitEthernet 1/0/17
Info : You are recommended to save the configuration now; otherwise, it will be lost after
system reboot.
[Sysname-irf-port1/2] quit
[Sysname] interface ten-gigabitethernet 1/0/17
[Sysname-Ten-GigabitEthernet1/0/17] undo shutdown
[Sysname-Ten-GigabitEthernet1/0/17] quit
# Save the configuration so the IRF port settings can take effect after the device reboots.
[Sysname] save
