CAUTION: Restoring the standalone mode of a member device also removes that device from the IRF fabric. If you continue to use that device on the network, IP or bridge MAC conflict might occur. You must reconfigure the device or the IRF fabric to remove the conflict. |
To set up an IRF fabric, you must place all member devices in IRF mode. In standalone mode, a device cannot form an IRF fabric with other devices.
As a best practice, configure member IDs, priorities, and IRF port settings for the member devices before you place them in IRF mode.
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.

Parameters
member member-id: Specifies the member ID of a member device. The value range for this argument is 1 to 4. On the CR16018-F router, 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 4. On the CR16018-F router, 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 interface items. Each interface item specifies one interface in the interface-type interface-number form. The interfaces are bound to IRF-port 1. You can specify a maximum of eight interface items.
irf-port2 interface-list2: Specifies a space-separated list of interface items. Each interface item specifies one interface in the interface-type interface-number form. The interfaces are bound to IRF-port 2. You can specify a maximum of eight interface items.A physical interface can be bound to only 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 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 3, set the domain ID to 10, configure the member priority as 10, and bind Ten-GigabitEthernet 3/1/1 and Ten-GigabitEthernet 3/1/2 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.
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.

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 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 BootWare menus to delete files.

Parameters
domain-id: Specifies a domain ID for the IRF fabric. The value range is 0 to 4294967295.
Usage guidelines
|
|
CAUTION: Changing the IRF domain ID of an IRF member device will remove that member device from the IRF fabric. This member device will be unable to exchange IRF protocol packets with the remaining member devices in the IRF fabric. |
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 following commands: irf domain or mad 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-detect-time
Use irf link-detect-time to set the quick IRF link failure detection interval on a relayed IRF fabric.
Use undo irf link-detect-time to restore the default.
Syntax
irf link-detect-time interval
undo irf link-detect-time
Default
The quick IRF link failure detection interval is 100 milliseconds.
Views
System view
Predefined user roles
network-admin
Parameters
interval: Sets a quick IRF link failure detection interval in the range of 10 to 3000 milliseconds.
Usage guidelines
Quick IRF link failure detection helps eliminate packet loss when IRF connections are established over Layer 2 relay devices between remote IRF member devices.
The quick IRF link failure detection mechanism tests the IRF links at intervals set by using this command. If a member device has not received detection packets from its neighbor over an IRF link for three detection intervals, the member device determines that the IRF link has failed. Then, it reports the link failure to the CPU and switches traffic over to available IRF links.
The quick IRF link failure detection mechanism operates independently of the regular link state change detection mechanism on a port. The link down report delay set by using the irf link-delay command applies to the regular link state change detection mechanism, but it does not apply to the quick IRF link failure detection mechanism. If both mechanisms detect that the link is down, the port reports only the link down event reported by the quicker one of the two mechanisms.
For this command to operate correctly, you must specify a unique IRF packet VLAN for the physical interfaces of each IRF link when you execute the port group interface command.
As a best practice, set the quick IRF link detection interval to 10 milliseconds if the following intervals are set to 100 milliseconds:
|
Command |
Interval description |
|
bfd min-echo-receive-interval |
The minimum interval for receiving BFD echo packets. |
|
bfd min-transmit-interval bfd min-receive-interval |
The minimum intervals for sending and receiving BFD single-hop control packets, respectively. |
|
bfd multi-hop min-transmit-interval bfd multi-hop min-receive-interval |
The minimum interval for sending and receiving BFD multi-hop control packets. |
For more information about BFD, see High Availability Configuration Guide.
Examples
# Set the IRF link detection interval to 500 milliseconds.
<Sysname> system-view

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

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 IRF fabric runs BFD, make sure the delay interval is shorter than the maximum BFD session lifetime. For more information about BFD, see High Availability Configuration Guide.
On a relayed IRF fabric, the quick IRF link failure detection mechanism enabled by using the irf link-detect-time command operates independently of the regular link state change detection mechanism on a port. The link down report delay setting applies to the regular link state change detection mechanism, but it does not apply to the IRF link failure detection mechanism. If both mechanisms detect that the link is down, the port reports only the link down event reported by the quicker one of the two mechanisms.
Examples
# Set the IRF link down report delay to 300 milliseconds.

[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.

System view
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.
Usage guidelines
|
|
CAUTION: IRF bridge MAC address change will cause transient traffic disruption. |
Before you replace an IRF fabric entirely, you can configure the new IRF fabric with the bridge MAC address of the existing IRF fabric to minimize service interruption.
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.
You must make sure the IRF bridge MAC address is unique on the switched LAN after the replacement.
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 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.
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
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 does not change after the address owner leaves the fabric.
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 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
|
|
CAUTION: IRF bridge MAC address change will cause transient traffic disruption. |
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.
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.
When you use this command, follow these restrictions and guidelines:
· This command does not take effect if the IRF bridge MAC address is configured 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. 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.

Parameters
member-id: Specifies the ID of an IRF member. The value range for the member ID is 1 to 4. On the CR16018-F router, the member ID must be 1 or 2.
new-member-id: Assigns a new ID to the IRF member. The value range for the member ID is 1 to 4. On the CR16018-F router, the member ID must 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 1 and 2, respectively. After you interchange their member IDs, their port settings also interchange.
To set the member ID of a device in standalone mode, use the irf member command.
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
If you reboot the device after executing the irf member 1 renumber 2 command, the device member ID changes to 2 at system reboot. Using undo irf member 1 renumber cannot restore the member ID to 1. You must use the irf member 2 renumber 1 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
To configure and activate IRF-port 1/2 when the port is in DIS state:
# Bind Ten-GigabitEthernet 1/3/1/2 to IRF-port 1/2.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/3/1/2

Usage guidelines
When you configure BFD MAD on a VLAN interface, the BFD MAD VLAN cannot be used for any other purposes and can contain only dedicated BFD MAD ports. Loops might occur if you assign network interfaces to the BFD MAD VLAN.
To avoid loops, you can configure the Layer 2 Ethernet ports used for BFD MAD as dedicated BFD MAD ports. Dedicated BFD MAD ports process only BFD MAD packets with all other packets dropped.
Use this command only on the ports used for BFD MAD because this command disables a common Ethernet port from processing service traffic.
You can configure only one port on a card as a dedicated BFD MAD port if the card has IRF physical interfaces.
Examples
# Configure Ten-GigabitEthernet 1/3/1/2 as a dedicated BFD MAD port.

When you configure BFD MAD on a VLAN interface, follow these guidelines:
|
Category |
Restrictions and guidelines |
|
BFD MAD VLAN |
· Do not enable BFD 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 BFD MAD. ¡ On the IRF fabric and the intermediate device, assign the ports of BFD MAD links to the BFD MAD VLAN. ¡ On the IRF fabric, create a VLAN interface for the BFD MAD VLAN. · Make sure the IRF fabrics on the network use different BFD MAD VLANs. · Make sure the BFD MAD VLAN 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 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. · Do not assign IRF physical interfaces to the BFD MAD VLAN or use the Layer 2 Ethernet interfaces in the BFD MAD VLAN as IRF physical interfaces. · If you are using a VLAN-based IRF deployment over Layer 2 relay devices, you must execute the mad bfd dedicated command to specify the physical interfaces assigned to the BFD MAD VLAN on the IRF member devices as dedicated BFD MAD ports. In addition, do not use the BFD MAD VLAN on the relay devices for any purposes other than BFD MAD. · On the IRF fabric, member ports of the BFD MAD VLAN can be located on IRF-connect cards or non-IRF-connect cards, but not both. · If you use ports on the IRF connection cards for BFD MAD, you can assign only one Layer 2 Ethernet interface from each IRF-connect card to the BFD MAD VLAN. |
|
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. |
Examples

Use undo mad enable to disable LACP MAD.
Syntax

Default
LACP MAD is disabled.
Views

Predefined user roles
network-admin
Usage guidelines
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 or mad enable. The IRF domain IDs configured by using these 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

mad exclude interface
Use mad exclude interface to exclude an interface 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 an interface when it transits to the Recovery state upon detection of a multi-active collision.
Syntax
mad exclude interface interface-type interface-number
undo mad exclude interface interface-type interface-number
Default
Except for the interfaces automatically excluded by the system, all common network interfaces shut down when the IRF fabric transits to the Recovery state. The system automatically excludes the following network interfaces from being shut down:
· IRF physical interfaces.
· Member interfaces of an aggregate interface if the aggregate interface is excluded from being shut down.
Views
System view
Predefined user roles
network-admin
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 for the interfaces used for Telnet.
Do not exclude the following interfaces from the shutdown action:
· Aggregate interfaces used for MAD and their member ports.
· VLAN interfaces used for MAD and the Ethernet ports in the VLANs.
The interfaces 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 interfaces.
Examples
# Exclude Ten-GigabitEthernet 1/3/1/2 from being shut down when the MAD status 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 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 VLAN-interface 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.
mode enhanced: Sets the binding mode to enhanced for the IRF physical interface.
vlan vlan-id: Specifies an IRF packet VLAN for the interface to receive and send IRF packets. The value range for the vlan-id argument is 2 to 4093. Use this option only on a relayed IRF fabric, in which the IRF member devices are connected through Layer 2 devices.
Usage guidelines
|
|
CAUTION: Use the undo port group interface command with caution. If the physical interface is the only up member interface of the IRF port, the IRF fabric will split after you remove the binding. |
Execute this command multiple times to bind multiple physical interfaces to an IRF port. You can bind a maximum of 16 physical interfaces to an IRF port. The physical interfaces bound to the same IRF port can be distributed on a maximum of eight cards.
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.
When you specify an IRF packet VLAN for an IRF physical interface, follow these restrictions and guidelines:
· Specify a unique VLAN for each IRF physical link. Do not use these VLANs for any other purposes than transmitting IRF protocol packets.
· Make sure the two ends of each IRF physical link use the same VLAN ID.
· If you specify an IRF packet VLAN for an IRF physical link multiple times, the most recent configuration takes effect.
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.
