IRF configuration commands
chassis convert mode irf
Use chassis convert mode irf to enable IRF mode.
Use undo chassis convert mode to restore standalone mode.
Syntax
chassis convert mode irf
undo chassis convert mode

Usage guidelines
To set up an IRF fabric, place all its member devices in IRF mode after configuring their member ID,
priority, and IRF port settings. In standalone mode, a device cannot form an IRF fabric with other
devices.
After removing a device from an IRF fabric, change its operating mode to standalone. In IRF mode,
the device forms a single-member IRF fabric, and the IRF protocol still runs on the device to
consume system resources.
Save any configuration you have made before changing the device to operate in a different mode,
because the device will automatically reboot to make the new operating mode take effect.
Make sure you have assigned a member ID to each IRF member device before you enable the IRF
mode. If no member ID is assigned, two hyphens (--) is displayed in the output of the MemberID
field from the display irf-configuration command.
Examples
# Enable IRF mode.
<Sysname> system-view
[Sysname] chassis convert mode irf
The device will switch to IRF mode and reboot. You are recommended to save the current
running configuration and specify the configuration file for the next startup. Continue?
[Y/N]:y

Parameters
chassis chassis-number [ slot slot-number ]: Specifies an IRF member device or a card in the IRF
fabric. The chassis-number argument represents the ID of an IRF member device, and the
slot-number argument represents the slot number of a card. If an IRF member device is specified
but a card is not specified, this command displays all restricted ports on that device. If neither IRF
member ID nor card slot number is specified, this command displays all restricted ports in the IRF
fabric.
Usage guidelines
The restricted ports in an IRF fabric cannot receive or forward multicast packets.
Examples
# Display the restricted ports on the card in slot 4 of IRF member 1.
[Sysname]display restricted port chassis 1 slot 4
Chassis: 1
slot: 4

irf auto-merge enable
Use irf auto-merge enable to enable auto reboot for IRF fabric merge. The function enables an IRF
fabric to automatically reboot its member devices when it is defeated in the master election during
an IRF fabric merge.
Use undo irf auto-merge enable to disable this function.
8

Syntax
irf auto-merge enable
undo irf auto-merge enable
Default
This function is disabled. To complete an IRF merge, you must manually reboot the IRF fabric that
has been defeated in the master election.
Views

mdc-admin
Usage guidelines
To avoid an auto reboot failure, make sure the auto reboot function is enabled on both IRF fabrics
that are merging.
This command is available in IRF mode. The configuration of this command will be lost when you
change to the standalone mode, even if you have saved the configuration.
The auto reboot 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.
If two IRF members are connected with relay devices, the link failure between relay devices cannot
cause the IRF fabric to split within 20 seconds. When the time limit exceeds, the IRF fabric splits.
The member devices of the IRF fabric defeated in the master election will reboot automatically to
join the reunited IRF fabric after the IRF link recovers, regardless of whether the auto reboot
function is enabled or not.
Examples
# Enable auto reboot for IRF fabric merge.
<Sysname> system-view
[Sysname] irf auto-merge enable
irf auto-update enable
Use irf auto-update enable to enable the software auto-update function for propagating software
images of the master in an IRF fabric to all its members.
Use undo irf auto-update enable to disable the software auto-update function.
Syntax
irf auto-update enable
undo irf auto-update enable
Default
The software auto-update function is enabled.

Usage guidelines
To join an IRF fabric, a device must use the same set of software images as the master in the fabric.
The software auto-update function automatically synchronizes the current software images of the
master in an IRF fabric to all its members.
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 no sufficient storage space is 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 Boot menu to delete some files.
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 automatically downloads the current software images of the
master, sets the downloaded images as its main startup software images, and automatically reboots
with the new software images to rejoin the IRF fabric.
If the device you are adding to the IRF fabric is incompatible with the software version running on
the master, the software auto-update function cannot work correctly. For more information about
the software version, see the release note for that version.
When the master is propagating its software images to the member devices, do not remove or
reboot the active MPU of each member device, and make sure the IRF links between each pair of
member devices are all in up state.
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.
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.
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 an IRF fabric.
Use undo irf domain to restore the default IRF domain setting.
Syntax

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. Changing the operating mode from IRF to standalone can
cause loss of the IRF domain setting, even if 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 you use a member in one IRF fabric as the intermediate device for performing LACP MAD or ARP
MAD for another IRF fabric, assign the two IRF fabrics different domain IDs to avoid false detection
of IRF split.
Examples
# Set the IRF domain ID to 30.
<Sysname> system-view
[Sysname] irf domain 30
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 0 milliseconds.
Views

Parameters
interval: Sets the IRF link down report delay in the range of 0 to 2000 milliseconds. If the interval is
set to 0, link down events are reported without any delay.
Usage guidelines
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the irf link-delay setting, even if you have saved the configuration.
11

An IRF link down report delay helps avoid link flapping causing 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.
Examples
# Set the IRF link down report delay to 300 milliseconds.
<Sysname> system-view
[Sysname] irf link-delay 300
irf link-status detect enable
Use irf link-status detect enable to enable IRF link failure detection.
Use undo irf link-status detect enable to disable this function.
Syntax
irf link-status detect enable
undo irf link-status detect enable
Default
The IRF link failure detection is enabled.

Usage guidelines
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the undo irf link-status detect enable command configuration, even if you have
saved the configuration.
After the IRF link failure detection is enabled, the system automatically examines the status of each
IRF physical link to discover IRF link failure events.
Examples
# Disable the IRF link failure detection.
<Sysname> system-view
[Sysname] undo irf link-status detect enable
irf link-status auto-recovery enable
Use irf link-status auto-recovery enable to enable the IRF link failure auto recovery.
12

Use undo irf link-status auto-recovery enable to disable this function.
Syntax
irf link-status auto-recovery enable
undo irf link-status auto-recovery enable
Default
The IRF link failure auto recovery is enabled.
Views

Usage guidelines
The IRF link failure auto recovery enables the system to recover the failed IRF links automatically.
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the undo irf link-status auto-recovery enable command configuration, even if you
have saved the configuration.
The command setting does not take effect if the IRF link failure detection is disabled.
Examples
# Disable the IRF link failure auto recovery.
<Sysname> system-view
[Sysname] undo irf link-status auto-recovery enable
irf mac-address persistent
Use irf mac-address persistent to configure IRF bridge MAC persistence so the IRF fabric continues
using the bridge MAC address of the old master as its bridge MAC address for a period of time
after a master re-election.
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
Bridge MAC address of the IRF fabric does not change after the master leaves.
Views

13

Parameters
always: Enables the IRF bridge MAC address to be permanent regardless of master re-election or
leaving of the master.
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
Bridge MAC persistence is available in IRF mode. Changing the operating mode from IRF to
standalone can cause loss of the bridge MAC persistence setting, even if you have saved the
configuration.
An IRF fabric by default uses the bridge MAC address of the master device as its bridge MAC
address. This bridge MAC address is used by Layer 2 protocols, for example, LACP, to identify the
IRF fabric, and must be unique on a switched LAN for proper communication.
To avoid duplicate bridge MAC addresses, an IRF fabric can automatically change its bridge MAC
address after its master leaves, but the change causes temporary service interruption. Depending
on your network condition, you can enable the IRF fabric to preserve or change its bridge MAC
address after the master leaves.
If ARP MAD is used, execute the undo irf mac-address persistent command to enable immediate
bridge MAC address change after a master leaves.
If VRRP load balancing is used, execute the irf mac-address persistent always command to prevent
the IRF bridge MAC address from changing. For more information about VRRP, see High Availability
Configuration Guide.
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
irf member
Use irf member to assign a member ID to the device in standalone mode.
Use undo irf member to restore the default.
Syntax
irf member member-id
undo irf member
Default
The device operates in standalone mode and has no member ID.

Parameters
member-id: Assigns an IRF member ID to the device. Value range is 1 to 4.
Usage guidelines
You must assign an IRF member ID to a device before enabling its IRF mode. The member ID takes
effect after the IRF mode is enabled. This member ID must be unique among all IRF member
devices.
To change the member ID of a device in IRF mode, use the irf member member-id renumber
new-member-id command. The new member ID takes effect at reboot.
Examples
# Assign member ID 2 to the device in standalone mode.
<Sysname> system-view
[sysname] irf member 2
Info: Member ID change will take effect after the member reboots and operates in IRF mode.

irf member description
Use irf member description to configure a description for an IRF member.
Use undo irf member description to restore the default.
Syntax
irf member member-id description text
undo irf member member-id description
Default
No description is configured for any IRF member.

Parameters
member-id: Specifies the ID of an IRF member.
text: Configures the IRF member description, a string of 1 to 127 characters.
Usage guidelines
Configure a description to identify the physical location or purpose of an IRF member for easy
maintenance.
This command is available in IRF mode. Changing the operating mode from IRF to standalone can
cause loss of the IRF member description, even if you have saved the configuration.

irf member priority
Use irf member priority to change the priority of an IRF member.
Use undo irf member priority to restore the default.
Syntax
irf member member-id priority priority
undo irf member member-id priority
Default
IRF member priority is 1.

Parameters
member-id: Specifies an IRF member ID.
priority: Sets priority in the range of 1 to 32.
Usage guidelines
Change member priority assignment to affect the maser election result. The greater the priority
value, the higher the priority. A member with higher priority is more likely to be the master.
This command is available in IRF mode. The new priority setting takes effect at the next master
election, and does not trigger master election.
To assign an IRF priority to a device in standalone mode, use the irf priority command.
Examples
# Set the priority of IRF member 2 to 32.
<Sysname> system-view
[Sysname] irf member 2 priority 32
Related commands
irf priority
irf member renumber
Use irf member renumber to change the member ID of a device in the IRF fabric.
Use undo irf member renumber to restore the previous IRF member ID of the device.
16

Syntax
irf member member-id renumber new-member-id
undo irf member member-id renumber
Default
In IRF mode, the device by default uses the member ID set by using the irf member command.

Parameters
member-id: Specifies the ID of an IRF member device, in the range of 1 to 4.
new-member-id: Assigns a new ID to the IRF member device, in the range of 1 to 4.
Usage guidelines
CAUTION:
In IRF mode, an IRF member ID change can invalidate member ID relevant settings
(including interface and file path settings) and even cause data loss. Be sure you fully
understand its impact on your live network.
Before enabling IRF mode, you must use the irf member command to assign a unique member ID
to each member device in standalone mode. If two member devices have the same member ID,
they cannot join the same IRF fabric.
After IRF mode is enabled, change member IDs before making any other configuration.
After an IRF fabric is formed, make sure you understand the impact of the member ID change on
your network.
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. This command loses effect after you reboot the member device.
Examples
# Change the member ID of an IRF member from 2 to 4.
<Sysname> system-view
[Sysname] irf member 2 renumber 4
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]y
# Before rebooting the device, cancel the change in the preceding example.
[Sysname] undo irf member 2 renumber
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]y
