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)
SFP+/QSFP+ transceiver modules and optical fibers. The topology is the same as

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see HPE 5510 HI Switch Series Fundamentals Configuration Guide) to configure their
member IDs, member priorities, and IRF port bindings.
Follow these guidelines when you configure IRF settings on 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 can
perform IRF port binding before or after connecting IRF physical ports, depending on the
To bind a port on an interface card to an IRF port, you must install the interface card first. For
the interface card installation procedure, see
Execute the display irf configuration command to verify the basic IRF settings.

Connecting the physical IRF ports
As a best practice to avoid loop topology, first complete IRF configuration and then connect the IRF
Use SFP+/QSFP+ DAC cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF
member switches as planned.
