Connecting the IRF member switches in a ToR solution
Procedure
You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.
Figure 33: ToR cabling on page 42Figure 32 shows an example for connecting four top of rack IRF member switches by
using SFP+/QSFP+ network cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the same as
Figure 32: IRF fabric topology on page 42.

Configuring basic IRF settings
Configure basic IRF settings after you install the IRF member switches, power on the switches, and log in to each IRF member
switch to configure their member IDs, member priorities, and IRF port bindings.
Procedure
1. 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.
• Execute the display irf configuration command to verify the basic IRF settings.

Connecting the physical IRF ports
NOTE: Wear an ESD wrist strap when you connect SFP+ network cables or SFP+ transceiver modules and fibers. For how to
connect them, see SFP/SFP+/XFP Transceiver Modules Installation Guide and QSFP+ Transceiver Modules/Cables Installation
Guide.
