Several Expandable Resilient Networking (XRN) supported switches can be 
interconnected to form a fabric, in which each switch is a unit, the ports 
connecting the units are called fabric ports, and the other ports that are used to 
connect the fabric to users are called user ports. In this way, you can increase ports 
of network devices and improve the reliability of user networks.

Configure unit ID, unit name, XRN fabric name, and fabric authentication mode 
for three switches to enable them to form an XRN fabric.

The configuration details are as follows:

■

Unit IDs for Switch A, Switch B and Switch C are 1, 2 and 3 respectively;
