SPECIFICATION:

H3C S5120V3-LI switch series supports IRF2 technology that allows multiple physical devices it connects to be virtualized into one logical device.

In this way, users can manage and use these multiple devices as a single device. IRF can bring the following benefits to users:

• Simplified management: Once an IRF is built, users can log into the unified logical device by connecting to any port of any member. By configuring a single device, users can manage the whole intelligent resilient system and all member devices in the system, without physically connecting to each member device for configuration and management.
• Simplified services: Various control protocols running on the logical device formed by IRF are running as if they are on one device. For example, routing protocols perform the unified calculation as one device. With the application of cross-device link aggregation technology, the original spanning tree protocol will be replaced. This avoids a great number of protocol packet exchanges among the members, simplifies network operation, and shortens the convergence time during network flapping.
• Elastic extension: Elastic extension can be achieved according to user needs to ensure user investment. And the new device can achieve a “hot swap” when adding or leaving IRF, without affecting the normal operation of other devices.
