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

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.
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 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.
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?

Parameters
member member-id: Specifies the member ID of a member device. The value range for the member
ID is 1 to 8. For an HPE FlexFabric 12916E switch, the member ID must be 1 or 5. For an HPE
FlexFabric 12908E switch, the member ID must be 1 or 3. For an HPE FlexFabric12904E switch, the
member ID must be 1 or 2.
renumber new-member-id: Specifies a new member ID for the device. The value range for the
member ID is 1 to 8. For an HPE FlexFabric 12916E switch, the member ID must be 1 or 5. For an
HPE FlexFabric 12908E switch, the member ID must be 1 or 3. For an HPE FlexFabric 12904E
switch, 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 only to one IRF port.
Usage guidelines
This command is supported only in IRF mode.

This command bulk-configures basic IRF settings for a member device, 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 IRF 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.
Examples
# Bulk-configure basic IRF settings by using the non-interactive method. Change the member ID
from 1 to 2, set the domain ID to 10, configure the member priority as 10, and bind HundredGigE

Predefined user roles
network-admin
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.

11
For a successful merge, make sure IRF auto-merge is enabled on the 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.
Examples
# Enable IRF auto-merge.

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 new 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.
Software auto-update takes effect on an MPU only when ISSU compatible upgrade is supported
between the software versions of the MPU and the global active MPU. To identify whether the

12
software versions support ISSU compatible upgrade, see ISSU compatibility list in the release notes
for the device.

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 or ARP MAD, 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 by using the following
commands: irf domain, mad enable, or mad arp enable. The IRF domain IDs configured by using
these commands overwrite each other.
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 time is 4 seconds.

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.
Set the delay to 0 seconds in the following situations:
•The IRF fabric requires a fast master/subordinate or IRF link switchover.
•The BFD or GR 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
Use irf mac-address to specify a MAC address as the IRF bridge MAC address.
Use undo irf mac-address to restore the default.
Syntax
irf mac-address mac-address
undo irf mac-address
Default
An IRF fabric uses the bridge MAC address of the master device as the IRF bridge MAC address.

Predefined user roles
network-admin
Parameters
mac-address: Specifies a MAC address in the format of H-H-H. The MAC address cannot be the
all-zero or all-F MAC address, or a multicast MAC address. You can omit the consecutive zeros at
the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001.

14
Usage guidelines
CAUTION:
IRF bridge MAC address change causes transient traffic disruption.
You can specify the bridge MAC address of an existing IRF fabric for a new IRF fabric to replace the
existing IRF fabric with transient packet loss.
This command is supported only in IRF mode.
When you change the operating mode from IRF to standalone, the IRF bridge MAC address
configuration is lost, regardless of whether you have saved the configuration.
On a switched LAN, the IRF bridge MAC address must be unique.
After you specify an IRF bridge MAC address, the IRF fabric always uses the specified address as
the IRF bridge MAC address.
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.
After IRF fabrics merge, the merged IRF fabric uses the bridge MAC address of the merging IRF
fabric that won the master election as the IRF bridge MAC address.
If an IRF fabric splits after you configure the IRF bridge MAC address, both the split IRF fabrics use
the configured bridge MAC address as the IRF bridge MAC address.
Examples
# Configure the IRF fabric to use c4ca-d9e0-8c3c as the IRF bridge MAC address.
<Sysname> system-view
[Sysname] irf mac-address c4ca-d9e0-8c3c
irf mac-address persistent always
Use irf mac-address persistent always to enable the IRF fabric to not change its bridge MAC
address after the address owner leaves.
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
undo irf mac-address persistent
Default
The IRF bridge MAC address does not change after the address owner leaves.

Usage guidelines
This command is supported only in IRF mode. When you change the operating mode from IRF to
standalone, the bridge MAC persistence setting is lost, regardless of whether you have saved the
configuration.

15
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.
This command does not take effect if the IRF bridge MAC address is configured by using the irf
mac-address mac-address command.
If ARPMAD is used with the spanning tree feature, disable IRF bridge MAC persistence by using the
undo irf mac-address persistent command. In addition, do not specify an IRF bridge MAC address
by using the irf mac-address mac-address command.
If the IRF fabric has cross-member aggregate links, do not use the undo irf mac-address
persistent command to avoid unnecessary traffic disruption.
By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC
address.
On a switched LAN, the IRF bridge MAC address must be unique for correct traffic transmission.
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 fabric to not change its bridge MAC address after the address owner leaves.
<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 does not have an IRF member ID.

Parameters
member-id: Assigns an IRF member ID to the device. The value range for this argument is 1 to 8. For
an HPE FlexFabric 12916E switch, the member ID must be 1 or 5. For an HPE FlexFabric 12908E
switch, the member ID must be 1 or 3. For an HPE FlexFabric 12904E switch, 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.
Examples
# (In standalone mode.)Assign member ID 2 to the device.

Parameters
member-id: Specifies an IRF member ID. The value range for IRF member IDs is 1 to 8. For an HPE
FlexFabric 12916E switch, the member ID must be 1 or 5. For an HPE FlexFabric 12908E switch, the
member ID must be 1 or 3. For an HPE FlexFabric 12904E switch, 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. To assign an IRF priority to a device in standalone
mode, use the irf priority command.
The new priority setting takes effect at the next master election, but it does not trigger a master
election.
Examples
# Set the priority of IRF member 2 to 32.
<Sysname> system-view
[Sysname] irf member 2 priority 32
