An Switch 5500Gs switch has two ports: up port and down port. Given a
switch, its up port is connected to the down port of another switch, and its
down port is connected to the up port of a third one.

On a Switch 5500Gs Ethernet switch, only two special cascade ports can be
configured as fabric ports. The two ports can only be used to form an XRN fabric,
rather than function as normal ports. Their port numbers are
configured as fabric ports. The two ports can only be used to form an XRN fabric,

An XRN fabric can be successfully built only when the fabric cables are connected
in the above mode.

Based on the networking requirements in Figure 71, interconnect the three Switch
5500Gs switches through their fabric ports as shown in the following figure:

Configuration Procedure
XRN fabric configuration on the Switch 5500
1 Configure Switch A.
# Bring up the fabric ports.
<3Com> system-view
[3Com] fabric-port GigabitEthernet 1/1/1 enable
[3Com] fabric-port GigabitEthernet 1/1/2 enable
# Configure the unit ID as 1.
[3Com] change self-unit to 1

When you modify the unit ID of a switch, the switch updates its configurations
automatically. The update process takes some time, during which you cannot
perform any configurations on the switch. If the system generates prompts after
you enter a command, wait for the update to be finished.
