Setting up an IRF fabric
You can use H3C IRF technology to connect and virtualize multiple switches into a large virtual
switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and
manageability.
The switch can set up an IRF fabric only with switches from the same switch series.

To set up an IRF fabric:
Step Description
1. Plan IRF fabric setup.
Plan the installation site and IRF fabric setup parameters:
• Planning IRF fabric size and the installation site
• Identifying the master switch and planning IRF member IDs
• Planning IRF topology and connections
• Identifying IRF physical ports on the member switches
• Planning the cabling scheme
Start
Plan IRF fabric setup
Install IRF member switches
Connect the grounding cables
and power cords
Power on the switches
Configure basic IRF settings
Connect the physical IRF ports
Subordinate switches reboot
and the IRF fabric is
automatically established
