[Sysname] chassis convert mode irf
This command will convert the device to IRF mode and the device will reboot. Are you sure?
[Y/N]: y
The device reboots automatically to switch its operating mode. After logging in to the device again,,
change the member ID of the device to 2.

[Y/N]:y
[Sysname] quit
<Sysname> reboot
The device reboots automatically to make the configuration of the member ID take effect. After logging
in to the device again, create IRF-port1 of the device, and bind it to the physical IRF port
Ten-GigabitEthernet 2/3/0/25, and then save the configurations.
