Table 6 Command output
Field Description
Multi-active recovery state
Whether the IRF fabric is in Recovery state.
•Yes—The IRF fabric is in Recovery state. When MAD detects that
an IRF fabric has split into multiple IRF fabrics, it allows one fabric
to forward traffic. All the other IRF fabrics are set to the Recovery
state. In Recovery state, MAD shuts down all physical ports in the
fabric except for the IRF physical interfaces and ports configured to
not shut down.
•No—The IRF fabric is not in Recovery state. The fabric is active
and can forward traffic.
Excluded ports (user-configured) Ports manually configured to not shut down when the IRF fabric transits
to the Recovery state.
Excluded ports
(system-configured) Ports set to not shut down by default when the IRF fabric transits to the Recovery state.
MAD status
MAD link status:
•Normal—The MAD link is operating correctly.
•Faulty—The MAD link is faulty. Check the interface or port for
connectivity or configuration problems.
•N/A—MAD link status cannot be detected. This field always
displays N/A if BFD MAD is enabled on a management Ethernet
port.
Member ID IRF member ID of the local device.
Port Member ports of the aggregate interface used for LACP MAD.
Neighbor IRF member ID of the neighbor member device.
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

8
Default
The software auto-update feature is enabled.
Views
System view
Predefined user roles
network-admin
Usage guidelines
This command automatically propagatesthe 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 menus to delete files.
You must manually update the new device with the software images running on the IRF fabric if
software auto-update is disabled.
Examples
# Enable the software auto-update feature.
<Sysname> system-view
[Sysname] irf auto-update enable
irf domain
Use irf domain to assign a domain ID to an 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
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 LACPMAD, ARP MAD or ND
MAD, you must assign the two IRF fabrics different domain IDs for correct split detection. False
detection causes IRF split.

9
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.
Examples
# Set the IRF domain ID to 30.
<Sysname> system-view
[Sysname] irf domain 30
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
The IRF link down event report delay is 1 second.
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. The greater the interval, the slower the
service recovery.
Usage guidelines
If the CFD or BFD feature is used in the IRF fabric, make sure the delay interval is shorter than the
maximum CCM lifetime and BFD session lifetime. For more information about CFD and BFD, see
High Availability Configuration Guide.
As a best practice, set the delay to 0 seconds in the following situations:
•The IRF fabric requires a quick master/subordinate or IRF link switchover.
•The BFD, BFD MAD, GR, or RRPP feature is used.
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 }

10
undo irf mac-address persistent
Default
Bridge MAC address of the IRF fabric does not change 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.
timer: Enables the IRF bridge MAC address to remain unchanged for 6 minutes after the address
owner leaves. If the address owner rejoins the IRF fabric within the time limit, the IRF bridge MAC
address does not change. If the address owner does not rejoin 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 using a bridge
MAC address as its bridge MAC address after the address owner leaves.
To prevent traffic interruption, follow these restrictions and guidelines:
•If ARP MAD or ND MAD is used, execute the undo irf mac-address persistent command to
disable IRF bridge MAC persistence.
•If TRILL is configured, configure the irf mac-address persistent always command to disable
IRF bridge MAC change. The persistence setting ensures that other devices in the TRILL
network can maintain correct network topology after the address owner leaves.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
Examples
# Enable the IRF bridge MAC address to be permanent.
<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.
Syntax
irf member member-id description text
undo irf member member-id description
Default
No description is configured for an IRF member device.

Examples
# Configure a description for IRF member 1.
<Sysname> system-view
[Sysname] irf member 1 description F1Num001
irf member priority
Use irf member priority to change the priority of an IRF member device.
Use undo irf member priority to restore the default.
Syntax
irf member member-id priority priority
undo irf member member-id priority
Default
The IRF member priority is 1.

network-admin
Parameters
member-id: Specifies an IRF member ID in the range of 1 to 10.
priority: Sets a 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
The new priority setting takes effect at the next master election, but it does not trigger a master
election.
Examples
# Set the priority of IRF member 2 to 32.
<Sysname> system-view
[Sysname] irf member 2 priority 32
irf member renumber
Use irf member renumber to change the IRF member ID of a device.
Use undo irf member renumber to restore the previous IRF member ID of the device.

Parameters
member-id: Specifies the ID of an IRF member device, in the range of 1 to 10.
new-member-id: Assigns a new ID to the IRF member device, in the range of 1 to 10.
Usage guidelines
CAUTION:
An 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.
The new IRF member ID, including the one set by using the undo irf member renumber command,
takes effect after you reboot the member device.
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 member ID of an IRF member from 2 to 4.
<Sysname> system-view
[Sysname] irf member 2 renumber 4
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 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 4 command, the device member
ID changes to 4 at system reboot. Using undo irf member 2 renumber cannot restore the member
ID to 2.
irf-port
Use irf-port to enter IRF port view.
Use undo irf-port to removing all port bindings on an IRF port.
Syntax
irf-port member-id/port-number
undo irf-port member-id/port-number

Parameters
member-id/port-number: Specifies an IRF port on an IRF member device. The member-id argument
represents the ID of the IRF member device. The port-number argument represents the IRF port
index and must be 1 or 2.
Usage guidelines
To bind physical interfaces to an IRF port, you must enter IRF port view.
Before you remove all port bindings on an IRF port, shut down all its physical interfaces.
Examples
# Enter the view of IRF-port 1 on member 1.
<Sysname> system-view
[Sysname] irf-port 1/1

irf-port global load-sharing mode
Use irf-port global load-sharing mode to set the global load sharing mode for IRF links.
Use undo irf-port global load-sharing mode to restore the default.
Syntax
irf-port global load-sharing mode { destination-ip | destination-mac | ingress-port | source-ip |
source-mac } *
undo irf-port global load-sharing mode
Default
The following are criteria for distributing different types of packets across IRF links:
•TCP/UDP packets—Source and destination TCP/UDP port numbers.
•Non-TCP/-UDP IP packets—Source and destination IP addresses.
•Non-IP packets (packets without an IP header)—Source and destination MAC addresses.

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.
ingress-port: Distributes packets across IRF member links based on incoming port. This keyword is
not supported in the current software version.
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 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.
