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 34 shows an example for connecting four top of rack IRF member switches by using
SFP+/QSFP+ cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the
same as
Figure 33 .

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 S6520-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 S6520-EI Switch Series Interface Cards User Guide
.
•
Execute the
display irf configuration
command to verify the basic IRF settings.
