IRF commands display irf Use display irf to display IRF fabric information, including the member ID, role, priority, bridge MAC address, and description of each IRF member. Syntax display irf Views Any view Predefined user roles network-admin network-operator Examples # Display IRF fabric information. <Sysname>...
Field Description Description you have configured for the member device. • If no description is configured, this field displays a dashed line (-----). • If the description exceeds the maximum number of characters that can be Description displayed, an ellipsis (…) is displayed in place of the exceeding text. To display the complete description, use the display current-configuration command.

NewID Member ID assigned to the device. This member ID takes effect at reboot. Physical interfaces bound to IRF-port 1. The bindings take effect at reboot. IRF-Port1 This field displays disable if no physical interfaces are bound to the IRF port.
Ten-GigabitEthernet2/0/28 DOWN Table 3 Command output Field Description Member ID IRF member ID. IRF port number: • IRF Port 1—IRF-port 1. • 2—IRF-port 2. Physical interfaces bound to the IRF port.

Field Description Link state of the IRF port: • UP—The IRF link is up. • DOWN—The IRF link is down because the port has no physical link or has not been activated by the irf-port-configuration active command. • DIS—No physical interfaces have been bound to the IRF port. You can Link use the port group interface command to bind a minimum of one physical interface to the IRF port depending on the network...

Views Any view Predefined user roles network-admin network-operator Parameters verbose: Displays detailed MAD information. If you do not specify this keyword, the command only displays whether a MAD mechanism is enabled or disabled. Examples # Display brief MAD information. MAD ARP enabled. MAD ND enabled.
Table 6 Command output Field Description 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.
Syntax irf auto-update enable undo irf auto-update enable Default The software auto-update function is enabled. Views System view Predefined user roles network-admin Usage guidelines To join an IRF fabric, a device must use the same software images as the master in the IRF fabric. The software auto-update function propagates the current software images of the master in an IRF fabric to all its members automatically.
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.
• When the IRF link changes from down to up, the link layer immediately reports the event to the IRF fabric. 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 heartbeat timeout settings of upper-layer protocols (for example, CFD).
If ARP MAD or ND MAD is used, disable IRF bridge MAC persistence by using the undo irf mac-address persistent command. Use the irf mac-address persistent always command on the IRF fabric that meets the following requirements: • The IRF fabric uses a daisy-chain topology. •...

Use undo irf member priority to restore the default. Syntax irf member member-id priority priority undo irf member member-id priority...
Predefined user roles network-admin Parameters member-id: Specifies the ID of an IRF member, in the range of 1 to 10. new-member-id: Assigns a new ID to the IRF member, in the range of 1 to 10. Usage guidelines CAUTION: IRF member ID change can cause losses of member ID-related configurations at reboot, including settings on physical interfaces.
Usage guidelines To bind physical interfaces to IRF ports for IRF connection, you must enter IRF port view. Before you remove all port bindings on an IRF port, shut down all its physical interfaces. Examples # Bind Ten-GigabitEthernet 3/0/25 to IRF-port 3/1. <Sysname>...
You can also configure a port-specific load sharing mode for an IRF port in IRF port view. 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. Examples # Configure the global IRF link load sharing mode to distribute traffic based on destination MAC address.
Examples # Configure a port-specific load sharing mode for IRF-port 1/1 to distribute traffic based on destination MAC address. <Sysname> system-view [Sysname] irf-port 1/1 [Sysname-irf-port1/1] irf-port load-sharing mode destination-mac irf-port-configuration active Use irf-port-configuration active to activate IRF ports.

Examples # Enable ARP MAD on VLAN-interface 3. <Sysname> system-view [Sysname] interface vlan-interface 3 [Sysname-Vlan-interface3] mad arp enable You need to assign a domain ID (range: 0-4294967295) [Current domain is: 0]: 1 The assigned domain ID is: 1 Related commands irf domain mad bfd enable Use mad bfd enable to enable BFD MAD.
Category Restrictions and guidelines 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 VLAN and VLAN interface used for BFD MAD. If you configure other features, both feature compatibility BFD MAD and other features on the interface might run incorrectly.
NOTE: 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 # Enable LACP MAD on Bridge-Aggregation 1, a Layer 2 dynamic aggregate interface.
Examples # Exclude GigabitEthernet 2/0/1 from being shut down when the MAD status transits to Recovery. <Sysname> system-view [Sysname] mad exclude interface gigabitethernet 2/0/1 Related commands mad restore mad ip address Use mad ip address to assign a MAD IP address to an IRF member on a VLAN interface for BFD MAD.

Related commands irf domain mad restore Use mad restore to restore the normal MAD state of the IRF fabric in Recovery state. Syntax mad restore Views System view Predefined user roles network-admin Usage guidelines If the active IRF fabric has failed to work before the IRF split problem is fixed, use this command to restore an IRF fabric in Recovery state.
