Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see "Accessing the switch for the first time") to configure their member IDs, member priorities, and IRF
port bindings.
Follow these guidelines when you configure the switches:
• First configure the member IDs, member priorities, and IRF port bindings for the IRF member
switches, save the configuration, connect the member switches, and change the operating mode of
the switches to IRF mode.
• 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.
• 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.
