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  H3C  S6520X-EI & S6520X-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. 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 display irf configuration command to verify the basic IRF settings. 
For more information about configuring basic IRF settings, see H3C S6520X-EI & S6520X-HI Switch 
Series Virtual Technologies Configuration Guide. 
Connecting the physical IRF ports 
Use  twisted pair/SFP+/QSFP+/SFP28/QSFP28  cables  or SFP+/QSFP+/SFP28/QSFP28 
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, 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 
H3C S6520X-EI & S6520X-HI 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 Table4-2.
