28Figure 33 IRF fabric topologyConnecting the IRF member switches in a ToR solutionYou 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 usingSFP+/QSFP+ cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is thesame as Figure 33.Figure 34 ToR cablingConfiguring basic IRF settingsAfter you install the IRF member switches, power on the switches, and log in to each IRF memberswitch (see H3C S6520-EI Switch Series Fundamentals Configuration Guide) to configure theirmember 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. Youperform IRF port binding before or after connecting IRF physical ports depending on thesoftware release.• To bind the ports on an interface card to an IRF port, you must install the interface card first. Forhow 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.For more information about configuring basic IRF settings, see H3C S6520-EI Switch Series IRFConfiguration Guide.
