Figure 5-6 shows an example for connecting 9 top of rack IRF member switches by using
SFP+/QSFP+ transceiver modules and optical fibers. The topology is the same as Figure

5.3 Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF
member switch (see "Chapter 2 IRF" of QX-S5500G Series Ethernet Switches
Configuration Guides) to configure their member IDs, member priorities, and IRF port
bindings.
Follow these guidelines when you configure the switches:
Assign the master switch higher member priority than any other switch.

Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch.

You perform IRF port binding before or after connecting IRF physical ports depending
on the software release.
To bind the ports on an interface card to an IRF port, you must install the interface card

first. For how to install an interface card, see "Appendix B FRUs and compatibility
matrixes".
Execute the display irf configuration command to verify the basic IRF settings.

For more information about configuring basic IRF settings, see "Chapter 2 IRF" of
QX-S5500G Series Ethernet Switches Configuration Guides.

5.4 Connecting the physical IRF ports

Use SFP+/QSFP+ DAC cables or SFP+/QSFP+ transceiver modules and fibers to connect
the IRF member switches as planned.
