•
The link aggregation must use dynamic aggregation mode.
•
The link aggregation must have a minimum of one member link from each member chassis.
•
If the intermediate device is also an IRF fabric, you must assign the two IRF fabrics different
domain IDs for correct split detection.
Procedures
Setting up the IRF fabric
1.
Configure Device A:
# Assign member ID 1 to Device A.
<DeviceA> system-view
[DeviceA] irf member 1
# Bind Ten-GigabitEthernet 3/0/1 and Ten-GigabitEthernet 3/0/2 to IRF-port 2.
[DeviceA] irf-port 2
[DeviceA-irf-port2] port group interface ten-gigabitethernet 3/0/1
[DeviceA-irf-port2] port group interface ten-gigabitethernet 3/0/2
[DeviceA-irf-port2] quit
# Save the running configuration to the main next-startup configuration file before changing the
operating mode to IRF.
IMPORTANT:
The mode change requires a system reboot, which causes all unsaved settings to be lost.
[DeviceA] save
# Enable IRF mode.
[DeviceA] chassis convert mode irf
The device will switch to IRF mode and reboot.
You are recommended to save the current running configuration and specify the
configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file cfa0:/
irf.cfg to make it available in stack mode? [Y/N]:y
Now rebooting, please wait...
2.
Configure Device B:
# Assign member ID 2 to Device B.
<DeviceB> system-view
[DeviceB] irf member 2
# Bind Ten-GigabitEthernet 3/0/1 and Ten-GigabitEthernet 3/0/2 to IRF-port 1.
[DeviceB] irf-port 1
[DeviceB-irf-port1] port group interface ten-gigabitethernet 3/0/1
[DeviceB-irf-port1] port group interface ten-gigabitethernet 3/0/2
[DeviceB-irf-port1] quit
# Save the configuration.
[DeviceB] save
# Connect the physical interfaces of IRF-port 2 on Device A to the physical interfaces of
IRF-port 1 on Device B, as shown in
. (Details not shown.)
# Enable IRF mode.
