Connecting the IRF member switches in a ToR solution
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR)
solution.
Figure 52 sh
ows an example for connecting 9 top of rack IRF member switches by using SFP+/
SFP28/QSFP+ transceiver modules and optical fibers. The topology is the same as Figure 51.

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see H3C S5560X-EI Switch Series Fundamentals Configuration Guide) 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 H3C S5560X-EI Switch Series Interface Cards User Guide.
• Execute the
display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S5560X-EI Switch Series IRF
Configuration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide,
depending on the software version.
Connecting the physical IRF ports
Use twisted pair/SFP+/SFP28/QSFP+ cables, or SFP+/SFP28/QSFP+ transceiver modules and
fibers to connect the IRF member switches as planned.
