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 youremove
the device from an IRF fabric.
The device automatically reboots for the mode change to take effect. During the reboot, you may
choose to have the system automatically convert the startup configuration file. Automatic
configuration conversion prevents chassis-, slot- or interface-related settings from becoming invalid.
For example, the system adds member ID information to interface numbers and file paths in IRF
mode.

Field Description
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 physical ports in the
fabric except for the IRF physical interfaces and ports configured to
not shut down.
•No—The IRF fabric is not in Recovery state. The fabric is active
and can forward traffic.
Excluded ports (user-configured) Ports manually configured to not shut down when the IRF fabric transits
to the Recovery state.
Excluded ports
(system-configured) Ports set to not shut down by default when the IRF fabric transits to the Recovery state.
MAD status

Usage guidelines
If the IRF auto-merge feature is disabled, you must follow the system instructions to manually reboot
member devices in the IRF fabric that fails master election.
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 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.

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 MPU automatically deletes the current software images. 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
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
irf domain domain-id
undo irf domain
Default
The IRF domain ID is 0.

mdc-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.
If one IRF fabric uses another IRF fabric as the intermediate device for LACPMAD, ARP MAD or ND
MAD, you must assign the two IRF fabrics different domain IDs for correct split detection. False
detection causes IRF split.

12
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using 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.
In an MDC environment, the irf domain command is available only on the default MDC. The mad
enable, mad arp enable, and mad nd enable commands are available on all MDCs. If you change
the IRF domain ID in one MDC, the IRF domain IDs in all other MDCs change automatically.
Examples
# Set the IRF domain ID to 30.
<Sysname> system-view
[Sysname] irf domain 30
irf isolate member
Use irf isolate member to isolate an unused IRF member ID.
Use undo irf isolate member to remove the isolation setting for an IRF member ID.
Syntax
irf isolate member member-id
undo irf isolate member member-id
Default
No IRF member IDs are isolated.
Views

mdc-admin
Parameters
member-id: Specifies an IRF member ID. Available values are IDs that have not been assigned.
Usage guidelines
This command is supported only in IRF mode.
CRC errors or traffic storms occur if an IRF member device tags inter-chassis packets with a valid
unused member ID. This issue is typically caused by poor-quality fiber modules, fibers, or cables on
IRF links.
To avoid CRC errors or traffic storms, isolate the unused member IDs in the valid member ID range.
When an unused member ID is isolated, the member devices will drop all packets that are tagged
with the member ID.
Before you assign an isolated member ID to a new member device, you must remove the isolation
setting for the member ID by using the undo irf isolate member command.
Examples
# Isolate IRF member ID 3.
<Sysname> system-view
[Sysname] irf isolate member 3

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 1 second.
Views
System view
Predefined user roles
network-admin
mdc-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. The greater the interval, the slower the
service recovery.
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 CFD or BFD feature is used in the IRF fabric, make sure the delay interval is shorter than the
maximum CCM lifetime and BFD session lifetime. For more information about CFD and BFD, see
High Availability Configuration Guide.
As a best practice, set the delay to 0 seconds in the following situations:
•The IRF fabric requires a quick master/subordinate or IRF link switchover.
•The BFD, BFD MAD, GR, or RRPP feature is used.
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.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent

14
Default
Bridge MAC address of the IRF fabric does not change after the address owner leaves.
Views
System view
Predefined user roles

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 address owner rejoins the IRF fabric within the time limit, the IRF bridge MAC
address does not change. If the address 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
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 undo form of this command is configured, bridge MAC address of the current master replaces
the original IRF bridge MAC as soon as the original address owner leaves.
If ARP MAD or ND MAD is used, execute the undo irf mac-address persistent command to
disable IRF bridge MAC persistence.
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 does not have a member ID.

Parameters
member-id: Assigns an IRF member ID to the device. The value range is 1 to 4.
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.
If no member ID is assigned to the device in standalone mode, the device uses a member ID of 1
after its operating mode changes to IRF.
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
# (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 device.

Parameters
member-id: Specifies the ID of an IRF member, in the range of 1 to 4.
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

Parameters
member-id: Specifies an IRF member ID in the range of 1 to 4.
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 available 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.
Examples
# (In IRF mode.) 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.
Syntax
irf member member-id renumber new-member-id
undo irf member member-id renumber
Default
In IRF mode, the device uses the member ID that is set in standalone mode. If no member ID is
assigned to the device in standalone mode, the device uses a member ID of 1 after its operating
mode changes to IRF.
