Power off the devices, connect IRF links as shown in
2.
Configure IRF port bindings:
3.
# Bind Ten-GigabitEthernet 1/1/2 to IRF-port 1/2 on Device A and save the configuration.
<DeviceA> system-view
[DeviceA] interface ten-gigabitethernet 1/1/2
[DeviceA-Ten-GigabitEthernet1/1/2] shutdown
[DeviceA-Ten-GigabitEthernet1/1/2] quit
[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
# Bind Ten-GigabitEthernet 2/1/1 to IRF-port 2/1 on Device B and save the configuration.
<DeviceB> system-view
[DeviceB] interface ten-gigabitethernet 2/1/1
[DeviceB-Ten-GigabitEthernet2/1/1] shutdown
[DeviceB-Ten-GigabitEthernet2/1/1] quit

[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/1/1
[DeviceB-irf-port2/1] quit
[DeviceB] interface ten-gigabitethernet 2/1/1
[DeviceB-Ten-GigabitEthernet2/1/1] undo shutdown
[DeviceB-Ten-GigabitEthernet2/1/1] save
# Activate IRF port configuration on Device A.
[DeviceA-Ten-GigabitEthernet1/1/2] quit
[DeviceA] irf-port-configuration active
# Activate IRF port configuration on Device B.
[DeviceB-Ten-GigabitEthernet2/1/1] quit
[DeviceB] irf-port-configuration active
After the IRF port configuration is activated, the two devices automatically elect a master. In this
example, Device A is the master. Device B automatically reboots and joins the Device A as a
subordinate to form an IRF fabric. The system name of the IRF fabric is DevcieA.
Configure LACP MAD:
4.
# Create a dynamic aggregate interface and enable LACP MAD. Because LACP MAD is not run
between IRF domains, you can use the default value 0.
<DeviceA> system-view
[DeviceA] interface bridge-aggregation 2
[DeviceA-Bridge-Aggregation2] link-aggregation mode dynamic
[DeviceA-Bridge-Aggregation2] mad enable
You need to assign a domain ID (range: 0-4294967295)
Figure 12, and power on the two devices.
