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.
Figure4-6
shows 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 Figure4-5.

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
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.
