Parameters
member member-id: Specifies the member ID of a member device. The value range for the
member ID is 1 to 10.
BFD MAD details:
• Member ID—IRF member ID of the local device.
• MAD IP address—MAD IP address of a member device.
• Neighbor—IRF member ID of the neighboring member device.
• MAD status—BFD MAD link state. Options include Normal and Faulty.
renumber new-member-id: Specifies a new member ID for the device. The value range for the
member ID is 1 to 10. 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 four interface items. Each
interface item specifies one interface in the
irf-port2 interface-list2: Specifies interfaces bound to IRF-port 2. A physical interface

• 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 be t ween
interfaces.
To remove an IRF physical interface from an IRF port, you must use the

Usage guidelines
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 sp ace 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 men u to delete files.

Parameters
domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
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, ARP MAD, or ND
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. Y ou can change the IRF domain ID by using the following
commands:
IDs configured by using these commands overwrite each other.
Examples
# Set the IRF domain ID to 10.

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
When you configure the IRF link down report delay, follow these restrictions and guidelines:
• Make sure the IRF link down report delay is shorter than the heart beat or hello timeout settings
of upper-layer protocols (for example, CFD and OSPF). If the report delay is longer than the
timeout setting of a protocol, unnecessary recalculations might occur.
• Set the delay to 0 seconds in the following situations:
{ The IRF fabric requires a fast master/subordinate or IRF link switchover.
{ The RRPP, BFD, or GR feature is used.
{ You want to shut down an IRF physical i nterface or reboot an IRF member device. (After you
complete the operation, reconfigure the delay depending on the network condition.)
Examples
# Set the IRF link down report delay to 300 milliseconds.

Syntax

Default
An IRF fabric uses the bridge MAC address of the master device as the IRF bridge MAC address.

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.
Usage guidelines
CAUTION:
IRF bridge MAC address change causes transient traffic disruption .
12
When you replace an IRF fabric as a whole, you can configure the new IRF fabric with the bridge
MAC address of the existing IRF fabric before the replacement to minimize service interruption.
You must make sure the IRF bridge MAC address is unique on the switched LAN.
After you specify an IRF bridge MAC address, the IRF fabric always uses the specified address as
the IRF bridge MAC address.
If the IRF fabric splits after you configure the IRF bridge MAC address, both of the split IRF fabrics
use the configured bridge MAC address as the IRF bridge MAC addre ss.
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.
Examples
# Configure the IRF fabric to use c4ca-d9e0-8c3c as the IRF bridge MAC address.

Syntax

Parameters
always: Enables the IRF bridge MAC address to be permanent. The IRF bridge MAC ad dress 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 addre ss 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
If the undo form of this command is used, bridge MAC address of the current master replaces the
original IRF bridge MAC as soon as the original address owner leav es.
This command does not take effect if the IRF bridge MAC address is configured by using the

Usage guidelines
CAUTION:
IRF member ID change can invalidate member ID-related settings, including interface and file path
settings, and cause data loss. Make sure you fully understand its impact on your live network.
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
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.
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 2 and 3,
respectively. After you interchange their member IDs, their port settings also interchange.
Examples
# Change the ID of an IRF member device from 1 to 2.

After connecting the physical interfaces between two devices and binding them to the correct IRF
ports, you must use this command to activate the settings on the IRF ports. This command merges
the two devices into one IRF fabric.
The system activates the IRF port settings automatically in the following situations:
• The configuration file that the device starts with contains IRF port bindings.
• You are binding physical interfaces to an IRF port after an IRF fabric is formed.
Examples
To configure and activate IRF-port 1/2 when the port is in DIS state:
