configuration steps
For ease of distinction, in the configuration below, it is assumed that the system name of Device A is DeviceA before the formation of the IRF, the system name of Device B is Device B, and the system name of the intermediate device Device C is DeviceC.
(1) Configure the device number
# Device A retains the default number as 1 and does not need to be configured.
# Change the member number of the device to 2 on Device B.
<DeviceB> system-view
[DeviceB] irf member 1 renumber 2
Warning: Renumbering the switch number may result in configuration change or loss. Continue? [Y/N]:y
[DeviceB]
(2) After powering off the two devices, connect the IRF link as shown, and then power on the two devices.
# Create IRF port 2 on Device A, bind it to physical port Ten-GigabitEthernet1/1/2, and save the configuration.
<DeviceA> system-view
[DeviceA] interface ten-gigabitethernet 1/1/2
[DeviceA-Ten-GigabitEthernet1/1/2] shutdown
[DeviceA] irf-port 1/2
[DeviceA-irf-port1/2] port group interface ten-gigabitethernet 1/1/2
[DeviceA-irf-port1/2] quit
[DeviceA] interface ten-gigabitethernet 1/1/2
[DeviceA-Ten-GigabitEthernet1/1/2] undo shutdown
[DeviceA-Ten-GigabitEthernet1/1/2] save
# Create IRF port 1 on Device B, bind it to physical port Ten-GigabitEthernet2/2/1, and save the configuration.
<DeviceB> system-view
[DeviceB] interface ten-gigabitethernet 2/2/1
[DeviceB-Ten-GigabitEthernet2/2/1] shutdown
[DeviceB] irf-port 2/1
[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/2/1
[DeviceB-irf-port2/1] quit
[DeviceB] interface ten-gigabitethernet 2/2/1
[DeviceB-Ten-GigabitEthernet2/2/1] undo shutdown
[DeviceB-Ten-GigabitEthernet2/2/1] save
# Activate the IRF port configuration of DeviceA.
[DeviceA-Ten-GigabitEthernet1/1/2] quit
[DeviceA] irf-port-configuration active
# Activate the IRF port configuration of DeviceB.
[DeviceB-Ten-GigabitEthernet2/2/1] quit
[DeviceB] irf-port-configuration active
(3) There will be a master election between the two devices, and the one that loses the election will automatically restart. After the restart is completed, an IRF will be formed, and the system name will be unified as DeviceA.
