3. Configure Device A as the DHCP server:
# Enable DHCP.
<DeviceA> system-view
[DeviceA] dhcp enable
# Configure address pool 1 to assign IP addresses on subnet 192.168.1.0/24 to clients.
[DeviceA] dhcp server ip-pool 1
[DeviceA-dhcp-pool-1] network 192.168.1.0 24
# Enable the DHCP server on Ten-GigabitEthernet 1/0/1.
[DeviceA] interface Ten-GigabitEthernet 1/0/1
[DeviceA-Ten-GigabitEthernet1/0/1] dhcp select server
[DeviceA-Ten-GigabitEthernet1/0/1] quit
# Specify the URL of the script file for the clients.
[DeviceA-dhcp-pool-1] bootfile-name http://192.168.1.40/device.py
[DeviceA-dhcp-pool-1] quit
4. Power on Switch A and Switch B.
Switch A and Switch B will obtain the Python script file from the DHCP server and execute the script.
After completing the IRF configuration, Switch A and Switch B reboot.
5. After Switch A and Switch B start up again, use a cable to connect Switch A and Switch B through
their IRF physical ports.
Switch A and Switch B will elect a master member. The subordinate member will reboot to join the
IRF fabric.
Verifying the configuration
# On Switch A, display IRF member devices. You can also use the display irf command on Switch B to
display IRF member devices.
<Switch A> display irf
