Analysis: The "reached max units" message indicates that the maximum number of 
units allowed by the current fabric is reached. You will fail to add new devices to the 
fabric in this case.

Solution: Remove the new device or existing devices in the fabric.

Analysis: The "different system name" message indicates the fabric name of the 
device directly connected to the switch and the existing fabric name of the fabric are 
not the same. Only the devices with the same fabric name can form a Fabric.

Solution: Configure the fabric name of the new device to be that of the fabric.

Analysis: The "different product version" message indicates the software version of 
the directly connected device and that of the current device are not the same. A 
device can join a fabric only when its software version is identical to that of the fabric.

Solution: Make sure the software version of the new device is the same as that of the 
fabric.

Analysis: The "auth failure" message indicates error occurs when the switch 
authenticates a directly connected device. The error may occur if the XRN fabric 
authentication modes configured for the both devices are not the same, or the 
password configured does not match.

Solution: Make sure the XRN fabric authentication modes and the passwords 
configured for the both devices are the same.

On a Switch 5500 series switch, four GigabitEthernet ports can operate as fabric 
ports. The four ports are grouped into two groups. One group comprises of 
GigabitEthernet1/1/1 and GigabitEthernet1/1/2 ports, the other comprises of 
GigabitEthernet1/1/3 and GigabitEthernet1/1/4 ports. Only the ports of one group 
can operate as fabric ports at a time. Of the ports in the two groups, 
GigabitEthernet1/1/1 and GigabitEthernet1/1/3 ports can operate as UP fabric ports, 
and GigabitEthernet1/1/2 and GigabitEthernet1/1/4 ports can operates as DOWN 
fabric ports.

You can configure a port to be a fabric port using the fabric port command. Once 
you configure a port to be a fabric port, the group to which the port belongs 
becomes a fabric port group, and the other port in the group becomes a fabric port 
automatically. For example, after you configure the GigabitEthernet1/1/1 port to be a 
fabric port (a UP fabric port) by executing the fabric port GigabitEthernet1/1/1 
enable command, the port group becomes a fabric port group, and 
GigabitEthernet1/1/2 port, which belongs to the same port group, becomes a DOWN 
fabric port.
