Configuring basic IRF settings
After you install the IRF member switches, power on the switches, and log in to each IRF member switch
(see "Connecting your switch to the network") 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 S12500-X Switch Series IRF
Configuration Guide.
Connecting the physical IRF ports
Follow these guidelines when you select transceiver modules and cables:
•
Use twisted pair cables to connect 10Gbase-T ports for short distance connection.
•
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+/CFP/CFP2 ports, connect the transmit port of an SFP+/CFP/CFP2
transceiver module at one end to the receive port of an SFP+/CFP/CFP2 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 CFP transceiver modules and fibers to connect CFP ports.
•
Use CXP transceiver modules and fibers to connect CXP ports.
•
Use CFP2 transceiver modules and fibers to connect CFP2 ports.
•
The transceiver modules at the two ends of an IRF link must be of the same type.
For more information about installing transceiver modules, see "Installing FRUs." For more information
about connecting fibers, see "Connecting your switch to the network."
