•
Use Category 6A (or above) twisted-pair cables to connect 10GBase-T Ethernet ports in a short
distance.
•
Use SFP+ DAC cables to connect SFP+ ports in a short distance.
•
Use SFP+ transceiver modules and fibers to connect SFP+ ports in a long distance.
•
The transceiver modules at the two ends of an IRF link must be the same type.
For more information about the transceiver modules and DAC cables, see the switch installation
guide and
H3C Transceiver Modules User Guide
.
NOTE:
The transceiver modules and DAC cables available for the switch are subject to change over time.
For the most up-to-date list of transceiver modules and DAC cables, contact your H3C sales
representative.
Connecting IRF ports
When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on
one member to the physical interfaces of IRF-port 2 on the other.
Configuration backup
As a best practice, back up the next-startup configuration file on a device before adding the device to
an IRF fabric as a subordinate.
A subordinate device's next-startup configuration file might be overwritten if the master and the
subordinate use the same file name for their next-startup configuration files. You can use the backup
file to restore the original configuration after removing the subordinate from the IRF fabric.
Setup and configuration task list
As a best practice, use the basic IRF setup procedure in
. Perform the tasks in this figure on
each member device.
