Page 15: Display Switchover State
Field Description MAD status: • Detect—The IRF virtual device is normal, and MAD is detecting multi-active collisions. • Recovery—The IRF virtual device is in recovery state. When detecting a multi-active collision, MAD places the IRF virtual device with higher master ID in recovery state and shuts down all physical ports in the Current MAD status device but the IRF ports and the ports that are configured not to shut down. -
Page 16: Irf Auto-Update Enable
Description Use the display switchover state command to display the master/slave switchover state in the IRF virtual device. Examples # Display the master/slave switchover states of the master. <Sysname> display switchover state Master HA State to slot 2: Realtime backup to slave. Master HA State to slot 3: Slave is absent. -
Page 17: Irf Domain
Parameters None Description Use the irf auto-update enable command to automatically synchronize the boot file of the master switch to the switch you are adding to the IRF virtual device. Use the undo irf auto-update enable command to disable this function. By default, this function is enabled. -

The value range is 200 to 2000. -
Page 19: Irf Member Description
timer: Enables the IRF virtual device to preserve its bridge MAC address for six minutes after the master leaves. Description Use the irf mac-address persistent command to enable the IRF virtual device to preserve its bridge MAC address for a certain period after the master leaves. Use the undo irf mac-address persistent command to enable the IRF virtual device to change its bridge MAC address as soon as the master leaves. -

Use the undo irf-port load-sharing mode command to restore the default. By default, the S5120-EI series switches use the combination of source and destination MAC addresses as the hash key when processing Layer 2 packets, and use the combination of source and destination IP addresses when processing Layer 3 packets. -

Use the undo irf-port load-sharing mode command to restore the default. By default, the S5120-EI series switches use the combination of the source and destination MAC addresses as the hash key when processing Layer 2 packets, and use the combination of the source and destination IP addresses when processing Layer 3 packets. -

traffic and to ensure the uniqueness of the IRF virtual devices. All of the service ports are shut down but the IRF ports and those manually configured not to shut down. When a MAD-enabled IRF virtual device splits into two or more identical active IRF virtual devices, all the IRF virtual devices but the one with the lowest master ID are placed in the recovery state to stop forwarding traffic and to ensure the uniqueness of the IRF virtual devices. -
