IRF commands
chassis convert mode irf
Use chassis convert mode irf to enable IRF mode.
Use undo chassis convert mode to restore the default.
Syntax
chassis convert mode irf
undo chassis convert mode
Default
The device operates in standalone mode.
Views
System view
Predefined user roles
network-admin
Usage guidelines
To set up an IRF fabric, place all member devices in IRF mode after you configure member IDs,
priorities, and IRF port settings for the member devices. In standalone mode, a device cannot form
an IRF fabric with other devices.
IRF generates packets on a device in IRF mode even if the device does not form an IRF fabric with
any other devices. To conserve system resources, set a device to standalone mode after removing it
from an IRF fabric.
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
Do you want to convert the content of the next startup configuration file flash:/startup.cfg
to make it available in IRF mode? [Y/N]:y
Now rebooting, please wait...
# Restore standalone mode.
<Sysname> system-view
[Sysname] undo chassis convert mode
The device will switch to stand-alone 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
Do you want to convert the content of the next startup configuration file flash:/startup.cfg
to make it available in stand-alone mode? [Y/N]:y

Multi-active recovery state
Whether the IRF fabric is in Recovery state:
•Yes—The IRF fabric is in Recovery state. When MAD detects that an IRF
fabric has split into multiple IRF fabrics, it allows one fabric to forward
traffic.All the other IRF fabrics are set to the Recovery state. In Recovery
state, MAD shuts down all service interfaces in the fabric except for the
following service interfaces:
{IRF physical interfaces.
{Service interfaces configured to not shut down.
•No—The IRF fabric is not in Recovery state. It is active and can forward
traffic.
Excluded
ports(user-configured) Service interfaces manually configured to not shut down when the IRF fabric transits to the Recovery state.
Excluded
ports(system-configured) Service interfaces set to not shut down by default when the IRF fabric transits to the Recovery state. These service interfaces are not user configurable.
MAD status
MAD operating status:
•Normal—The MAD mechanism is operating correctly.
•Faulty—The MAD mechanism is not operating correctly. Check the
interface or port for connectivity or configuration problems. For example,
verify that all member devices have member ports used for LACP MAD.
•N/A—MAD link status cannot be detected.
Member ID IRF member ID of the local device.
Port Member ports of the aggregate interface used for LACP MAD.
Neighbor IRF member ID of the neighbor member device.

Parameters
member member-id: Specifies the member ID of a member device. The member ID must be 1 or 2.
renumber new-member-id: Specifies a new member ID for the device. The member ID must be 1 or
2. The member device automatically reboots for the new member ID to take effect. If you do not
specify this option, the command does not change the member ID.
domain domain-id: Specifies an IRF domain ID in the range of 0 to 4294967295. Assign the same
domain ID to all devices you are adding to the same IRF fabric.
priority priority: Specifies an IRF priority in the range of 1 to 32. The greater the priority value, the
higher the priority. A member with higher priority is more likely to be the master.
irf-port1 interface-list1: Specifies a space-separated list of up to eight interface items. Each interface
item specifies one interface in the interface-type interface-number form. The interfaces are bound to
IRF-port 1.
irf-port2 interface-list2: Specifies a space-separated list of up to eight interface items. Each interface
item specifies one interface in the interface-type interface-number form. The interfaces are bound to
IRF-port 2. A physical interface can be bound to only one IRF port.
Usage guidelines
This command bulk-configures basic IRF settings fora device in IRF mode, including the member ID,
domain ID, priority, and IRF port bindings.
The easy IRF feature provides the following configuration methods:
•Interactive method—Enter the easy-irf command without parameters. The system will guide
you to set the parameters step by step.
•Non-interactive method—Enter the easy-irf command with parameters.
As a best practice, use the interactive method if you are new to IRF.
If you execute this command multiple times, the following settings take effect:
•The most recent settings for the member ID, domain ID, and priority.
•IRF port bindings added through executions of the command. You can bind a maximum of eight
physical interfaces to an IRF port.
When you specify physical interfaces for an IRF port, you must follow the IRF port binding
requirements in Virtual Technologies Configuration Guide.
If you specify physical interfaces by using the interactive method, you must also follow these
restrictions and guidelines:
•Do not enter spaces between the interface type and interface number.
•Use a comma (,) to separate two physical interfaces. No spaces are allowed between
interfaces.
To remove an IRF physical interface from an IRF port, you must use the undo port group interface
command in IRF port view.

irf auto-merge enable
Use irf auto-merge enable to enable IRF auto-merge. This command enables an IRF fabric to
automatically reboot its member devices if it fails in the master election during an IRF fabric merge.

11
Use undo irf auto-merge enable to disable IRF auto-merge.
Syntax
irf auto-merge enable
undo irf auto-merge enable
Default
IRF auto-merge is enabled. The IRF fabric that has failed in the master election reboots
automatically to complete the IRF fabric merge.
Views
System view
Predefined user roles
network-admin
Usage guidelines
For a successful merge, make sure IRF auto-merge is enabled on both IRF fabrics that are merging.
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the setting for this command is lost, regardless of whether you have saved the
configuration. To disable IRF auto-merge after you change the operating mode from standalone to
IRF, use the undo form of this command.
IRF auto-merge takes effect on merges caused by any of the following events:
•The IRF link recovers from a link failure.
•The IRF physical interfaces of the member devices are connected after the interfaces are
bound to IRF ports.
The feature does not take effect on a merge that occurs in the following conditions:
•You bind a physical interface to an IRF port.
•The interface has been connected to the peer IRF physical interface before the binding
operation.
If the IRF auto-merge feature does not take effect, you must save the running configuration, and then
follow the system instructions to manually reboot one or multiple member devices.
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

Usage guidelines
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the setting for this command is lost, regardless of whether you have saved the
configuration. To disable software auto-update after you change the operating mode from
standalone to IRF, use the undo form of this command.
This command automatically propagates the current software images of the master MPU in the IRF
fabric to any MPUs you are adding to the IRF fabric.
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 system automatically deletes the current software images of the MPU. 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 when
software auto-update is disabled.
Examples
# Enable the software auto-update feature.
<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
The IRF domain ID is 0.
Views
System 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
This command is supported only 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.
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 the commands
overwrite each other.

13
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view
[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 delay is 1000 milliseconds.
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
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the command configuration is lost, regardless of whether you have saved the
configuration.
If the BFD feature is used in the IRF fabric, make sure the delay interval is shorter than the BFD
session lifetime. For more information about BFD, 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.
Use undo irf mac-address persistent to enable the IRF fabric to change its bridge MAC address as
soon as the address owner leaves.

Parameters
always: Enables the IRF bridge MAC address to be permanent. The IRF bridge MAC address does
not change after the address owner leaves the fabric.
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 with the time limit, the IRF bridge MAC address does
not change. If the owner does not rejoin the IRF fabric 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.
Bridge MAC persistence is supported only in IRF mode. When you change the operating mode from
IRF to standalone, the bridge MAC persistence settingis lost, regardless of whether you have saved
the configuration.
If the IRF fabric has cross-member aggregate links, do not use the undo irf mac-address
persistent command.
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.
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.

[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 member ID is 1.

Parameters
member-id: Assigns an IRF member ID to the device. The member ID must be 1 or 2.
Usage guidelines
Assign an IRF member ID to a device before enabling IRF mode. The member ID takes effect after
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 renumber command. The
new member ID takes effect at reboot.
Examples
# (In standalone mode.)Assign member ID 2 to the device.
<Sysname> system-view
[Sysname] irf member 2

irf member renumber
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 an IRF member.

Parameters
member-id: Specifies the ID of an IRF member. The member ID must be 1 or 2.
text: Configures the IRF member description, a string of 1 to 127 characters.
Usage guidelines
Configure a description to describe the location or purpose of a member device.
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the IRF member description is lost, regardless of whether you have saved the
configuration.
Examples
# Configure a description for IRF member 1.
<Sysname> system-view
[Sysname] irf member 1 description F1Num001

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

Parameters
member-id: Specifies an IRF member ID. The member ID must be 1 or 2.
priority: Sets priority in the range of 1 to 32. The greater the priority value, the higher the priority. A
member with higher priority is more likely to be the master.
Usage guidelines
This command is supported only in IRF mode. The new priority setting takes effect at the next master
election, but it does not trigger a master election.
To assign an IRF priority to a device in standalone mode, use the irf priority command.
To display the ID and priority settings of IRF members, use the display irf command.
Examples
# (In IRF mode.) Set the priority of IRF member 2 to 32.
<Sysname> system-view
[Sysname] irf member 2 priority 32

irf member renumber
Use irf member renumber to change the IRF member ID of a device in IRF mode.
Use undo irf member renumber to restore the previous IRF member ID of the device.
Syntax
irf member member-id renumber new-member-id
undo irf member member-id renumber
Default
The device uses the member ID that is set in standalone mode.

Parameters
member-id: Specifies the ID of an IRF member. The member ID must be 1 or 2.
new-member-id: Assigns a new ID to the IRF member. The member ID must be 1 or 2.
Usage guidelines
CAUTION:
IRF member ID change can cause losses of member ID-related settings at reboot, including settings
on IRF physical interfaces.
To have the new ID take effect, you must reboot the IRF member. To cancel the member ID 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.
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.
Plan IRF member ID assignment before setting up an IRF fabric, and change member IDs before
configuring any other features.
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 1 and 2,
respectively. 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.
To set the member ID of a device in standalone mode, use the irf member command.
Examples
# (In IRF mode.) Change the ID of an IRF member from 2 to 1.
<Sysname> display irf
[Sysname] irf member 2 renumber 1
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]Y
# (In IRF mode.) 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
If you reboot the device after executing the irf member 2 renumber 1command, the device member
ID changes to 1 at system reboot. Using undo irf member 2 renumber cannot restore the member
ID to 2. You must use the irf member 1 renumber 2 command to reconfigure the member ID.
