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
# (Centralized devices in standalone mode.) Enable IRF mode.

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 two 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 two interface items. Each interface item specifies one interface in the interface-type interface-number form. The interfaces are bound to IRF-port 2.
Usage guidelines
This command bulk-configures basic IRF settings for a 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 two 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.
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

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.

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.
Centralized devices in IRF mode:
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 Boot ROM menu to delete files.
You must manually update the new device with the software images running on the IRF fabric when software auto-update is disabled.
Distributed devices in IRF mode:
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 Boot ROM menu 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.

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.
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
irf link-delay interval
undo irf link-delay
Default
A link down event is not delayed to report.
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 on the IRF fabric, make sure the delay interval is shorter than the maximum 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.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent
Views
System view
Default
IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves.
Predefined user roles
network-admin
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 to use 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 setting is lost, regardless of whether you have saved the configuration.
If the IRF fabric has multichassis aggregate links, do not use the undo irf mac-address persistent command. Use of this command might cause traffic disruption.
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.
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 bridge MAC address to persist forever.

Parameters
member-id: Specifies an IRF member ID. The IRF 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.

Parameters
member-id: Specifies the ID of an IRF member. The IRF member ID must be 1 or 2.
new-member-id: Assigns a new ID to the IRF member. The IRF member ID must be 1 or 2.
Usage guidelines
|
|
CAUTION: IRF member ID change can cause losses of member ID-related configurations 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 2 and 3, 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 1 command, 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.

Usage guidelines
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

Usage guidelines
BFD MAD uses the BFD protocol to detect multi-active collisions. This MAD mechanism can work with or without intermediate devices.
When you configure BFD MAD on a Layer 3 aggregate interface, follow these restrictions and guidelines:
|
Category |
Restrictions and guidelines |
|
BFD MAD-enabled Layer 3 aggregate interface |
The aggregate interface must operate in static aggregation mode. |
|
BFD MAD VLAN |
· On the intermediate device (if any), assign the ports on the BFD MAD links to the same VLAN. Do not assign the ports to an aggregate interface. If these ports are hybrid ports, make sure these ports are untagged members of their PVIDs. · If the intermediate device acts as a BFD MAD intermediate device for multiple IRF fabrics, assign different BFD MAD VLANs to the IRF fabrics. · Do not use the BFD MAD VLAN on the intermediate device for any purposes other than BFD MAD. · Make sure the BFD MAD VLAN on the intermediate device contains only ports on the BFD MAD links. Exclude a port from the BFD MAD VLAN if that port is not on a BFD MAD link. If you have assigned that port to all VLANs by using the port trunk permit vlan all command, use the undo port trunk permit command to exclude that port from the BFD MAD VLAN. |
|
BFD MAD-enabled Layer 3 aggregate interface and feature compatibility |
Do not use the BFD MAD-enabled interface and its member ports for any purposes other than configuring BFD MAD. Configure only the mad bfd enable and mad ip address commands on the BFD MAD-enabled interface. If you configure other features, both BFD MAD and other features on the interface might run incorrectly. |
|
MAD IP address |
· To avoid network issues, only use the mad ip address command to configure IP addresses on the BFD MAD-enabled interface. Do not configure an IP address by using the ip address command or configure a VRRP virtual address on the BFD MAD-enabled interface. · Make sure all the MAD IP addresses are on the same subnet. |
Examples
# Enable BFD MAD on Route-Aggregation 3.
<Sysname> system-view
[Sysname] interface route-aggregation 3

Use mad enable to enable LACP MAD.
Use undo mad enable to disable LACP MAD.
Syntax
mad enable
undo mad enable
Default
LACP MAD is disabled.
Views
Aggregate interface view
Predefined user roles
network-admin
Usage guidelines
LACP MAD uses extended LACP packets to detect multi-active collisions. This MAD mechanism requires an intermediate device that supports extended LACPDUs.
You must set up a dynamic link aggregation group that spans all IRF member devices between the IRF fabric and the intermediate device. To enable dynamic link aggregation, configure the link-aggregation mode dynamic command on the aggregate interface.
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.
When you use the mad enable command, the system prompts you to enter a domain ID. If you do not want to change the current domain ID, press enter at the prompt.
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
# Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] link-aggregation mode dynamic
[Sysname-Bridge-Aggregation1] mad enable

Use mad exclude interface to exclude a network port from being shut down when the IRF fabric transits to the Recovery state upon detection of a multi-active collision.
Use undo mad exclude interface to configure the IRF fabric to shut down a network port when it transits to the Recovery state upon detection of a multi-active collision.
Syntax
mad exclude interface interface-type interface-number

Default
All ports except the IRF physical interfaces and console ports shut down when the IRF fabric transits to the Recovery state.
Views
System view
Predefined user roles
network-admin
Parameters
interface-type interface-number: Specifies a port by its type and number.
Usage guidelines
If a port must be kept in up state for special purposes such as Telnet connection, exclude the port from the shutdown action. As a best practice to avoid incorrect traffic forwarding, do not exclude any ports except for the ports used for Telnet.
Do not exclude the MAD-enabled aggregate interfaces and their member ports from the shutdown action.
The ports that have been shut down by MAD come up when the member devices reboot to join the recovered IRF fabric. If auto recovery fails because the current master fails or any other exception occurs, use the mad restore command to manually recover the member devices and bring up the ports.
Examples
# (Centralized devices.) Exclude GigabitEthernet 1/0/1 from being shut down when the MAD status transits to Recovery.
<Sysname> system-view

Parameters
ip-address: Specifies an IP address in dotted decimal notation. This IP address is bound to an IRF member for BFD detection and is called a MAD IP address.
mask: Specifies a subnet mask in decimal dotted notation.
mask-length: Specifies a subnet mask in length, in the range of 0 to 32.
member member-id: Specifies the ID of an IRF member.
Usage guidelines
To use BFD MAD, configure a MAD IP address for each IRF member. Make sure all the MAD IP addresses are on the same subnet.
Do not configure a MAD IP address by using the ip address command or configure a VRRP virtual address on the BFD MAD-enabled interface.
The master attempts to establish BFD sessions with other member devices by using its MAD IP address as the source IP address.
· If the IRF fabric is integrated, only the MAD IP address of the master takes effect. The master cannot establish a BFD session with any other member. If you execute the display bfd session command, the state of the BFD sessions is Down.
· When the IRF fabric splits, the IP addresses of the masters in the partitioned IRF fabrics take effect. The masters can establish a BFD session. If you execute the display bfd session command, the state of the BFD session between the two devices is Up.
Examples
# Assign a MAD IP address to IRF member 1 on Route-Aggregation 3.

Parameters
interface-type interface-number: Specifies a physical interface by its type and number.
interface-name: Specifies a physical interface in the interface-typeinterface-number format. No space is allowed between the interface-type and interface-number arguments.
Usage guidelines
Bind a minimum of one physical interface to an IRF port for setting up an IRF connection. You can bind a maximum of two physical interfaces to an IRF port.
In IRF mode, use the shutdown command to shut down a physical interface before you bind it to or remove it from an IRF port. To bring up the physical interface after a binding or binding removal operation, use the undo shutdown command.
In standalone mode, the shutdown and undo shutdown operations are not required.
The system does not dynamically remove IRF port bindings when IRF links are lost, for example, because an interface card is removed. To remove IRF port bindings, you must use the undo port group interface command.
For more information about IRF port binding requirements, see Virtual Technologies Configuration Guide.
