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.

Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see the fundamentals configuration guide in the configuration guides for the switch series) 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.
•
To bind the ports on an interface module to an IRF port, you must install the interface module
first.
•
Execute the
For more information about configuring basic IRF settings, see the virtual technologies configuration
guide in the configuration guides for the switch series.
Connecting the physical IRF ports
Use
twisted
transceiver modules and fibers to connect the IRF member switches as planned.
Wear an ESD wrist strap when you connect twisted pair/SFP+/QSFP+/SFP28/QSFP28 cables or
SFP+/QSFP+/SFP28/QSFP28 transceiver modules and fibers. For how to connect them, see H3C
Transceiver Modules and Network Cables Installation Guide.
Verifying the IRF fabric setup
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, web, or SNMP to access the IRF fabric from the network management station. (See
the fundamentals configuration guide in the configuration guides for the switch series.)
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 Table4-2.
