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 switch to form an IRF fabric. The system name of the IRF fabric is
DevcieA

Configure ARP MAD:
# Enable the spanning tree feature globally on the IRF fabric to prevent loops.
