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.
Upon an operating mode change, the system automatically converts interface names by adding or
deleting the first number segment (the member ID) in the interface number. When performing this
task, the system converts every string in a valid interface name format without identifying whether or
not they are interface names. To avoid undesirable configuration changes that result from false
modification, do not name any objects except interfaces in a valid interface name format.
The following are valid interface name formats:
•
interface-type interface-number, which has a space between the two arguments.
•
interface-typeinterface-number, which does not have a space between the two arguments.

3
The system uses the space-separated format to match CPOS E1, E3, T1, and T3 interfaces and
uses the non-space format to match other types of physical interfaces.
If a string (except the string configured by using the description command) matches a valid
interface name, the system converts that string. For example, if a VLAN exists with a name of
GigabitEthernet0/7 in standalone mode, the VLAN name will change to GigabitEthernetn/0/7 in
IRF mode. The nargument represents the IRF member ID.
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] 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
member member-id: Specifies the member ID of a member device. The member ID can be 1 or 2.
renumber new-member-id: Specifies a new member ID for the device. The member ID can 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 interfaces bound to IRF-port 1. The
interface-list1 argument represents a space-separated list of up to two interface items. Each
interface item specifies one interface in the interface-type interface-number form.
irf-port2interface-list2: Specifies interfaces bound to IRF-port 2. A physical interface
can be bound to only one IRF port. The interface-list2 argument represents a
space-separated list of up to two interface items. Each interface item specifies one interface in the
interface-type interface-number form.

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 repeated executions of the command.
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.
Examples
# Bulk-configure basic IRF settings by using the non-interactive method. Change the member ID
from 2 to 1, set the domain ID to 10, configure the member priority as 10, and bind
Ten-GigabitEthernet 2/0/1 and Ten-GigabitEthernet 2/0/2 to IRF-port 1.

irf auto-merge enable
Use irf auto-merge enable to enable IRF auto-merge.
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
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.

13
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.
<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
irf auto-update enable
undo irf auto-update enable
Default
Software auto-update is enabled.

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 device in the IRF
fabric to any devices you are adding to the IRF fabric.
To ensure a successful software update, verify that the new 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. You must reboot the device, and then
access the BootWare menu to delete files.

irf domain
Use irf domain to assign a domain ID to the IRF fabric.
Use undo irf domain to restore the default.
Syntax
irf domain domain-id
undo irf domain
Default
The IRF domain ID is 0.

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 LACP 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 irf
domain or mad enable command. The IRF domain IDs configured by using the 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
