•
Bind physical ports to IRF-port 1 on one switch and to IRF-port 2 on the other switch.
•
Execute the
display irf configuration
command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see
H3C S9800 Switch Series IRF
Configuration Guide
.
Connecting the physical IRF ports
Follow these guidelines when you select transceiver modules and cables:
•
Use SFP+ transceiver modules and fibers for long-distance connection, or use SFP+ DAC
cables to connect SFP+ ports for short-distance connection.
•
When connecting SFP+ ports, connect the transmit port of an SFP+ transceiver module at one
end to the receive port of an SFP+ transceiver module at the other end.
•
Use QSFP+ transceiver modules and fibers for long-distance connection, or use QSFP+ DAC
cables to connect QSFP+ ports for short-distance connection.
•
Use CXP transceiver modules and fibers to connect CXP ports.
•
The transceiver modules at the two ends of an IRF link must be of the same type.

Verifying the IRF fabric configuration
After you finish configuring basic IRF settings and connecting IRF ports, verify the basic functionality
of the IRF fabric, as follows:
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
S9800 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

To avoid IP address collision and network problems, configure a minimum of one MAD mechanism to
detect the presence of multiple identical IRF fabrics and handle collisions. For more information
about MAD, see
H3C S9800 Switch Series IRF Configuration Guide.
