If the device is operating in standalone mode and will be added into an IRF, you must configure its
operating mode as the IRF mode, create IRF ports on it, perform other necessary configurations,
connect it with the IRF member(s) physically, and then it will join the IRF.
Follow these steps to switch the operating mode of the device:

Configuring IRF
Setting a Member ID for a Device
The member ID of a device defaults to 1. Before an IRF is formed, you need to manually number the two
devices respectively to avoid member ID collision.
You are recommended to set the member ID for a newly added device in the following way:
1) Plan the member IDs in advance. You can view the member IDs of an IRF, and find out an unused
ID for the new device.
2) If the device is already an IRF member, plug out the IRF cables.
3) Log in to the device to be added into the IRF, and change its member ID to the unused ID found out
in step 1.
4) Configure the IRF port(s) and other optional parameters.
5) Save the current configuration. Power off the device, connect the device with IRF cables and power
it on.
