Fabric cable connection mode of Switch 5500s
When building an XRN fabric of Switch 5500s, note the fabric cable connection
mode:

■
Multiple Switch 5500s are interconnected through their fabric ports.

A Switch 5500 has two fabric ports: left port and right port. Given a switch, its
left port is connected to the right port of another switch, and its right port is
connected to the left port of a third one.

On a Switch 5500, only four GigabitEthernet ports can be configured as fabric
ports. The four ports fall into two groups according to their port numbers
ports. The four ports fall into two groups according to their port numbers
■
GigabitEthernet 1/1/1 and GigabitEthernet 1/1/2 form the first group.
■
GigabitEthernet 1/1/3 and GigabitEthernet 1/1/4 form the second group.
Only one group of ports can be configured as fabric ports at a time.
GigabitEthernet 1/1/1 and GigabitEthernet 1/1/3 are the left fabric ports of the
first and the second group respectively, and GigabitEthernet 1/1/2 and
GigabitEthernet 1/1/4 are the right fabric ports or the first and the second group
respectively.
