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-port2 interface-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 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 1 to 2, set the domain ID to 10, configure the member priority as 10, and bind Ten-GigabitEthernet 1/2/5/1 and Ten-GigabitEthernet 1/2/5/2 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.
For a successful merge, make sure IRF auto-merge is enabled on the IRF fabrics that are merging.
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.
Views
System view
Predefined user roles
network-admin
Usage guidelines
This command automatically propagates the current software images of the master MPU in the IRF fabric to any devices or MPUs you are adding to the IRF fabric.
To ensure a successful software update, verify that the new device or 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 device or MPU automatically deletes the current software images. If the reclaimed space is still insufficient, the device or MPU cannot complete the auto-update. You must reboot the new device or the device that holds the new MPU, and then access the BootWare menu to delete files.
Examples
# Enable the software auto-update feature.

[Sysname] irf auto-update enable
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

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
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. 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.
The irf domain command is available only on the default context. The mad enable, mad arp enable, and mad nd enable commands are available on all contexts. If you change the IRF domain ID in one context, the IRF domain IDs in all other contexts change automatically.
Examples
# Set the IRF domain ID to 10.
<Sysname> system-view
[Sysname] irf domain 10
irf mac-address persistent
Use irf mac-address persistent to configure IRF bridge MAC persistence.
Use undo irf mac-address persistent to disable IRF bridge MAC persistence.
Syntax
irf mac-address persistent { always | timer }
undo irf mac-address persistent
Default
The IRF bridge MAC address remains unchanged for 6 minutes after the address owner leaves.
Views
System view
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 within 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
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 leaves.
If ARP MAD or ND MAD is used with the spanning tree feature, disable IRF bridge MAC persistence by using the undo irf mac-address persistent command.
If the IRF fabric uses a daisy-chain topology and has aggregate links with upstream or downstream devices, do not execute the undo irf mac-address persistent command. Use of this command might result in transmission delay or packet loss after the address owner leaves or reboots.
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.
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 bridge MAC address to persist forever.
<Sysname> system-view
[Sysname] irf mac-address persistent always
irf member description
Use irf member description to configure a description for an IRF member device.
Use undo irf member description to restore the default.

Predefined user roles
network-admin
Parameters
member-id: Specifies the ID of an IRF member. The IRF member ID can be 1 or 2.
new-member-id: Assigns a new ID to the IRF member. The member ID can be 1 or 2.
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 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.
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 1, 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.
<Sysname> display irf
[Sysname] irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]Y
# Before rebooting the device, cancel the change in the preceding example.
[Sysname] undo irf member 1 renumber
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]y

Parameters
destination-ip: Distributes traffic across IRF member links based on destination IP address.
destination-mac: Distributes packets across IRF member links based on destination MAC address.
source-ip: Distributes packets across IRF member links based on source IP address.
source-mac: Distributes packets across IRF member links based on source MAC address.
Usage guidelines
The global IRF link load sharing mode applies to all IRF ports in the IRF fabric. You can also configure a port-specific load sharing mode for an IRF port in IRF port view by using the irf-port load-sharing mode command.
An IRF port preferentially uses the port-specific load sharing mode. If no port-specific load sharing mode is available, the port uses the global load sharing mode.
You can configure the sharing mode to include a combination of multiple criteria for making traffic distribution decisions. If your device does not support a criterion combination, the system displays an error message.
If you configure the global load sharing mode multiple times, the most recent configuration takes effect.

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
To configure and activate IRF-port 1/2 when the port is in DIS state:
# Bind a physical interface to IRF-port 1/2.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/2/5/1
[Sysname-Ten-GigabitEthernet1/2/5/1] shutdown

[Sysname] irf-port 1/2
[Sysname-irf-port1/2] port group interface ten-gigabitethernet 1/2/5/1
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[Sysname-irf-port1/2] quit
[Sysname] interface ten-gigabitethernet 1/2/5/1
[Sysname-Ten-GigabitEthernet1/2/5/1] undo shutdown

ARP MAD VLAN |
· Do not enable ARP MAD on VLAN-interface 1. · If you are using an intermediate device, perform the following tasks: ¡ On the IRF fabric and the intermediate device, create a VLAN for ARP MAD. ¡ On the IRF fabric and the intermediate device, assign the ports of ARP MAD links to the ARP MAD VLAN. ¡ On the IRF fabric, create a VLAN interface for the ARP MAD VLAN. · As a best practice, do not use the ARP MAD VLAN for any other purposes. |
|
ARP MAD and feature configuration |
If an intermediate device is used, make sure the following requirements are met: · Run the spanning tree feature between the IRF fabric and the intermediate device to ensure that there is only one ARP MAD link in forwarding state. For more information about the spanning tree feature and its configuration, see Layer 2—LAN Switching Configuration Guide. · Enable the IRF fabric to change its bridge MAC address as soon as the address owner leaves. · If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for correct split detection. |
When you use the mad arp 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 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.
You can execute the mad arp enable command on any contexts. If you change the IRF domain ID in one context, the new IRF domain ID takes effect immediately on all contexts.

BFD MAD VLAN and feature compatibility |
Do not use the BFD MAD VLAN for any purposes other than configuring BFD MAD. · Use only the mad bfd enable and mad ip address commands on the BFD MAD-enabled VLAN interface. If you configure other features, both BFD MAD and other features on the interface might run incorrectly. · Disable the spanning tree feature on any Layer 2 Ethernet ports in the BFD MAD VLAN. The MAD feature is mutually exclusive with the spanning tree feature. |
|
MAD IP address |
· To avoid network issues, only use the mad ip address command to configure IP addresses on the BFD MAD-enabled VLAN interface. Do not configure an IP address by using the ip address command or configure a VRRP virtual address on the BFD MAD-enabled VLAN interface. · Make sure all the MAD IP addresses are on the same subnet. |
When you configure BFD MAD on a management Ethernet port, follow these restrictions and guidelines:
|
Category |
Restrictions and guidelines |
|
Management Ethernet ports for BFD MAD |
Connect a management Ethernet port on each member device to the common Ethernet ports on the intermediate device. To avoid BFD MAD failure caused by an active/standby MPU switchover, connect the management Ethernet port on each MPU to the intermediate device. |
|
BFD MAD VLAN |
· On the intermediate device, create a VLAN for BFD MAD, and assign the ports used for BFD MAD to the VLAN. On the IRF fabric, you do not need to assign the management Ethernet ports to the VLAN. · Make sure the IRF fabrics on the network use different BFD MAD VLANs. · Make sure the BFD MAD VLAN on the intermediate device contains only ports on the BFD MAD links. |
|
MAD IP address |
· Use the mad ip address command instead of the ip address command to configure MAD IP addresses on the BFD MAD-enabled management Ethernet ports. · Make sure all the MAD IP addresses are on the same subnet. |
When you configure BFD MAD on a Layer 3 aggregate interface, follow these restrictions and guidelines:
|
Category |

· Make sure the Layer 3 aggregate interface operates in static aggregation mode. · Make sure the member ports in the aggregation group do not exceed the maximum number of Selected ports allowed for an aggregation group. If the number of member ports exceeds the maximum number of Selected ports, some member ports cannot become Selected. BFD MAD will be unable to work correctly and its state will change to Faulty. |
|
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 the 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 |
Use 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. |

Usage guidelines
LACP MAD handles collisions differently than ARP MAD and ND MAD. To avoid conflicts, do not enable LACP MAD together with ARP MAD and ND MAD on an IRF fabric.
LACP MAD requires a device that supports extended LACPDUs for MAD to act as the intermediate device. 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 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.
You can execute the mad enable command on any contexts. If you change the IRF domain ID in one context, the new IRF domain ID takes effect immediately on all contexts.

Parameters
interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
If an interface must be kept in up state for special purposes such as Telnet connection, exclude the interface from the shutdown action. As a best practice to avoid incorrect traffic forwarding, do not exclude any interfaces except the interfaces used for Telnet.
The interfaces that have been shut down by MAD come up when the member devices reboot to join the recovered IRF fabric. If the active IRF fabric fails before the IRF link is recovered, use the mad restore command on the inactive IRF fabric to recover the inactive IRF fabric. This command also brings up all interfaces that were shut down by MAD.
Examples
# Exclude Ten-GigabitEthernet 1/2/5/1 from being shut down when the MAD state transits to Recovery.

Parameters
ip-address: Specifies an IP address in dotted decimal notation.
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 port or 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.

If one IRF fabric uses another IRF fabric as the intermediate device for ND 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 nd 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 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.
You can execute the mad nd enable command on any contexts. If you change the IRF domain ID in one context, the new IRF domain ID takes effect immediately on all contexts.

Usage guidelines
Execute this command multiple times to bind multiple physical interfaces to an IRF port. You can bind a maximum of two physical interfaces to an IRF port.
If you use both IRF and context features, make sure you establish the IRF fabric before you configure the context feature. If you configure the context feature on the device first, the context settings might be lost or cannot take effect after the device reboots to join an IRF fabric.
Use the shutdown command to shut down a physical interface before you bind it to or remove it from an IRF port in IRF mode. To bring up the physical interface after a binding or binding removal operation, use the undo shutdown command.
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.
