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. -
Page 21: Irf-Port Load-Sharing Mode
If you configure the global load sharing mode multiple times, the most recent configuration takes effect. 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. -
Page 22: Irf-Port-Configuration Active
You can configure an IRF port-specific load 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 port-specific load sharing mode multiple times on an IRF port, the most recent configuration takes effect. -

Page 27: Mad Exclude Interface
Usage guidelines LACP MAD uses extended LACP packets to detect multi-active collisions. This MAD mechanism requires an intermediate H3C device that supports extended LACPDUs. LACP MAD handles collisions differently than BFD MAD, ARP MAD, and ND MAD. To avoid conflicts, do not enable LACP MAD together with any of those mechanisms in an IRF fabric. -

Page 31: Port Group Interface
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. The recovered IRF fabric will take over the active IRF fabric role. Examples # Restore the normal MAD state of the IRF fabric in Recovery state. - Page 32 The system does not dynamically remove IRF port bindings when IRF links are lost, for example, because an expansion 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.
