Intelligent resilient framework 2 (IRF2)
H3C IE4320 series industrial switches support IRF2 (Second Generation Intelligent Resilient Architecture) technology, which connects multiple physical devices to each other, making it virtual as a logical device, that is, users can regard these multiple devices as a single device manage and use. H3C IE4320 series industrial switches can not only perform virtualization through 10G optical interfaces, but also can be virtualized through the gigabit optical port and the gigabit electrical port, and the IRF2 function can be realized through the network cable. IRF2 provides the following benefits:
Simplified management
After the IRF architecture is formed, it can be connected to any port of any device to log in to a unified logical device. By configuring a single device, the entire intelligent elastic system and all member devices in the system can be managed without physical connection. Configure and manage them separately on each member device.
Simplified business
The various control protocols running in the logical device formed by IRF are also run as a single device. For example, the routing protocol will be calculated as a single device. With the application of the cross-device link aggregation technology, it can replace the original spanning tree protocol, which saves the interaction of a large number of protocol packets between devices, simplifies network operation, and shortens the convergence time when the network is turbulent.
High performance
For Ethernet switches, the improvement in performance and port density is limited by the hardware structure. The performance and port density of an IRF system is the sum of the performance and port numbers of all devices inside the IRF. Therefore, IRF technology can easily expand the switching capability of the device and the density of user ports several times, thereby greatly improving the performance of the device.
High reliability
The high reliability of IRF is reflected in three aspects: link, equipment and protocol. The physical ports between the member devices support the aggregation function, and the physical connections between the IRF system and the upper- and lower-layer devices also support the aggregation function, which improves the reliability of the link through multi-link backup; the IRF system consists of multiple member devices. Once the master device fails, the system will quickly and automatically elect a new master to ensure uninterrupted services through the system, thus achieving device-level 1: N backup; the IRF system will have a real-time protocol hot backup function responsible for the configuration information of the protocol. Backup to all other member devices to achieve 1: N protocol reliability.
Bidirectional forwarding detection (BFD)
BFD provides millisecond-level detection for rapid link fault identification. By integrating with upper-layer routing protocols, BFD ensures fast route convergence to maintain service continuity. BFD establishes peer relationships between adjacent systems, where each system monitors the negotiated BFD packet rate from its peers. Detection intervals can be configured in millisecond increments. If a peer system fails to receive the predefined number of packets, it infers a failure in the BFD-protected infrastructure—whether it involves label-switched paths, tunnels, or Ethernet networks. BFD operates on the control plane of routers and other systems. Failures detected by BFD can be resolved either through forwarding plane recovery mechanisms or control plane remediation.
Smart management center (SmartMC)
SmartMC is H3C's latest offering and innovation that helps small and middle size enterprise network to address management issue and is free of charge, easy to use web management tool. SmartMC is embedded network management tool into the switch, it includes commander switches and other access switches.
SmartMC delivers the following benefits:
Intelligent operation
Once the switch is powered on and SmartMC function is enabled, topology will be created automatically and user can go enhanced web GUI to check the latest status.
Centralized management
All management can be achieved via commander switch such as centralized configuration backup, and software version management, increasing working efficiency.
Intelligent business
Mainly includes user management, etc.: After network access users are created and successfully activated, these users can access the SmartMC network through the one-key-armed port.
H3C IE4320 series industrial switches can be used as managed devices of SmartMC and connected to the SmartMC network as managed devices, enabling easy maintenance.
Support IEEE1588v2 protocol
IEEE 1588v2 is a master-slave synchronization system. During the synchronization process of the system, the master clock periodically publishes the PTP time synchronization protocol and time information, and the slave clock port receives the time stamp information sent by the master clock port, and the system calculates the master clock accordingly. Slave line time delay and master-slave time difference, and use the time difference to adjust the local time to keep the slave device time.
Frequency and phase coincident with master time. IEEE1588v2 can realize frequency synchronization and time synchronization at the same time. The accuracy of time transfer mainly depends on the accuracy of the two condition counters and the symmetry of the link. Compared with traditional timing technology, IEEE1588v2 has obvious advantages. It adopts two-way channel, the precision is ns level, the cost is low, and it can adapt to different access environments and so on. Under the background of the industry that requires increasing precision, IEEE 1588v2 has become an inevitable trend of development.
