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)
transceiver modules and optical fibers. The topology is the same as
Figure 38 Connecting top of rack switches
Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see HP A5500 HI 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.
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
Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see HP A5500 HI Switch Series IRF
Connecting the physical IRF ports
Use CX4/SFP+ cables or XFP/SFP+ transceiver modules and fibers to connect the IRF member switches
Wear an ESD-preventive wrist strap when you connect CX4/SFP+ cables or SFP+/XFP transceiver
modules and fibers. For how to connect them, see
"Installing/removing a CX4/SFP+
Accessing the IRF fabric to verify the configuration
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and
connecting IRF ports:
Log in to the IRF fabric through the console port of any member switch.
Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the
remote network management station can reach each other.
