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 71 sh
ows an example for connecting four top of rack IRF member switches. The topology is
the same as Figure 70.

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 S6850 & S9850 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.
• Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S6850 & S9850 Switch Series
IRF Configuration Guide.
Connecting the physical IRF ports
CAUTION:
Wear an ESD wrist strap when you install transceiver modules, fibers, and cables. For more
information, see the installation guide.
Use transceiver modules and fibers or cables to connect the IRF member switches as planned.
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:
1. Log in to the IRF fabric through the console port of any member switch.
2. Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the
remote network management station can reach each other.
3. Use Telnet or SNMP to access the IRF fabric from the network management station. (See H3C
S6850 & S9850 Switch Series Fundamentals Configuration Guide.)
4. Verify that you can manage all member switches as if they were one node.
5. Display the running status of the IRF fabric by using the commands in Table 7.
