240CHAPTER 26: XRN CONFIGURATION GUIDE
Fabric Cable Connection
n You are recommended to connect the switches with cables after the configuration in “Configuration Procedure” on page 241 “Configuration Procedure” on page 241.
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.
n 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
■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.
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 S3628P switches through their first group of fabric ports of as shown in the following figure:
