Introduction to IRF
Intelligent Resilient Framework (IRF), a feature particular to H3C S5600 series switches, is a new
technology for building the core of a network. This feature allows you to build an IRF fabric by
interconnecting several S5600 series switches to provide more ports for network devices and improve
the reliability of your network.

Establishment of an IRF Fabric

Topology and connections of an IRF fabric
An IRF fabric typically has a ring topology structure. As shown in
two special ports on the rear panel to connect with two other switches in the fabric. The two ports are
called fabric ports in general, UP port and DOWN port respectively; the other ports of the switch, which
are available for connections with users or devices outside the fabric, are called user ports.

A correctly built IRF fabric features the following:
Multiple S5600 series switches are interconnected through their fabric ports.
Given a switch, its UP port is connected to the DOWN port of another switch, and its DOWN port is
connected to the UP port of a third one.
