It supports IPv4/v6 static routing, routed port, RIP and OSPF (in small scale). In addition, it supports IGMP Snooping, DHCP Server, DHCP Client, DHCP Snooping, DHCP Relay (option 82) and Domain Name System (DNS).

H3C IE4500-G series industrial switches support Rapid Ring Protection Protocol (RRPP). The Rapid Ring Protection Protocol (RRPP) is a link layer protocol dedicated to Ethernet rings. It prevents broadcast storms caused by data loops when an Ethernet ring is healthy, and rapidly restores the communication paths between the nodes after a link is disconnected on the ring by bringing up the backup link. Compared with STP, RRPP has the following advantages: fast topology convergence (within 20 milliseconds); convergence time independent of Ethernet ring size. On intersecting rings, topology update of an RRPP ring does not ripple to other rings, data transmission thus becomes more stable. RRPP also supports load balancing in Ethernet rings, which improves physical link bandwidth utilization.

H3C IE4500-G series industrial switches implement full Ethernet security features. By enforcing multiple sets of security mechanisms, they effectively limit malware spread and traffic flow attack. The switches support layer 2 to 4 ACL control, block CPU, ARP, and DoS attacks. IEEE 802.1x port-based authentication is a client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports. TACACS+ and RADIUS authentication can implement centralized management for switches, and prevent unauthorized change in user allocation. They also support rapid deployment of End-point Admission Domination (EAD), as well as SAVI-based IPv6 source address validation.

Ethernet Ring Protection Switching (ERPS) is a ring network protection protocol defined by ITU, G.8032. It is a link layer protocol specially applied to the Ethernet ring network. When the Ethernet ring network is complete, it can prevent broadcast storms caused by the data loop, and when a link on the Ethernet ring network is disconnected, it can quickly restore the communication between various nodes on the ring network (within 20 milliseconds).

Intelligent resilient framework 2 (IRF2)

H3C IE4500-G 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 IE4500-G series industrial switches can not only perform virtualization through 10G optical interfaces, but also it 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 benefit:

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 significant 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.

Outstanding management

H3C IE4500-G series industrial switches management interface supports SNMPv1/V2/v3, Intelligent Management Center (iMC), Command Line Interface (CLI), Web based management, TELNET and FTP configuration. They also support SSH2.0 and SSL encryption to make management safer.

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.

One key device replacement

In case of one switch failure, the new added same type switch can download the same configuration and work as old switch immediately.

Software-defined networking (SDN)

Software-Defined Networking (SDN) is an innovative network architecture framework. Its core technology, OpenFlow, decouples the network control plane from the data forwarding plane, significantly simplifying network management and maintenance. More importantly, it enables flexible control over network traffic, providing a robust platform for core network and application innovation.

H3C IE4500-G series industrial switches support the OpenFlow 1.3 standard, allowing seamless switching between standard mode and OpenFlow mode. With large-scale flow table capabilities and compatibility with the H3C SDN controller at the access layer, these switches facilitate large-scale Layer 2 architecture networking and enable rapid user onboarding for existing networks. This dramatically reduces network management complexity and lowers operational costs. Additionally, the IE4500-G series can be integrated into H3C’s SNA (Seer Network Architecture), empowering customers to design cutting-edge network architectures and solutions. SNA offers a template library for network design, incorporating common enterprise networking models. By aligning with customer intent and leveraging industry best practices, SNA intelligently assists in network architecture planning. It also automates network deployment through features like intent-driven configuration, policy auto-provisioning, and plug-and-play fault recovery, eliminating reliance on command-line interfaces (CLIs). Whether deploying Underlay infrastructure or Overlay cloud-based services, SNA ensures full automation. Furthermore, SNA’s Network Seer Analyzer integrates big data-driven operational insights, connects to global defect databases and issue repositories, and shares worldwide maintenance expertise. Leveraging AI algorithms, it proactively monitors network and service health, predicts potential faults, and enables preemptive resolution, achieving true "predict and prevent" capabilities.

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.

PTP and SyncE support

IEEE 1588v2 (PTP) is a master-slave synchronization system. During synchronization, the master clock periodically distributes PTP timing protocols and timestamps, while slave clocks receive these timestamps to calculate path delay and clock offset. This enables precise adjustment of slave clock frequency and phase to align with the master clock. IEEE 1588v2 achieves both frequency and time synchronization, with accuracy relying on counter frequency stability and link symmetry. Compared to traditional timing technologies, IEEE 1588v2 offers significant advantages: bidirectional communication, 20-nanosecond-level precision, cost-effectiveness, and adaptability to diverse environments. As industries demand higher precision, IEEE 1588v2 has become the inevitable standard for advanced synchronization.

H3C IE4500-G series industrial switches support hardware-based IEEE 1588v2 and SyncE across all ports. Additionally, all ports on the IE4500-G series expansion modules are hardware-enabled for IEEE 1588v2 and SyncE.

iNQA (intelligent network quality analyzer)

H3C IE4500-G series industrial switches support iNQA (Intelligent Network Quality Analyzer), a detection mechanism designed for large-scale IP networks to rapidly measure network performance. H3C IE4500-G series industrial switches currently support packet loss measurement, including unidirectional (forward/reverse), bidirectional packet loss statistics (e.g., lost packet count, packet loss rate, lost byte count, byte loss rate). Leveraging these metrics enables rapid identification of packet loss timing, location, and severity.

eMDI (enhanced media delivery index)

H3C IE4500-G series industrial switches support eMDI (Enhanced Media Delivery Index), a network quality monitoring and fault demarcation solution specifically designed for video and audio services. eMDI directly monitors and analyzes service packets (carried over TCP or RTP) on specified network nodes in IP networks in real time. Network administrators can combine monitoring results from multiple nodes to quickly isolate fault locations.

Audio quality analysis

Multimedia audio and video services are widely used in daily life with diverse content, and user demands for service experience are increasingly stringent. Traditional network devices do not differentiate multimedia traffic from other data during transmission. During network congestion, multimedia services (e.g., audio/video) may experience stuttering, severely impacting user experience.

H3C IE4500-G series industrial switches support Quality of Service (QoS) analysis. It identifies SIP (Session Initiation Protocol)-based multimedia traffic. When enabled, the device prioritizes forwarding such traffic to ensure service quality. Additionally, it analyzes and collects traffic/session information, including flow statistics and session metadata, for performance optimization and troubleshooting.

Green features

H3C IE4500-G series industrial switches implement a variety of green energy saving features, including auto-power-down (port automatic energy saving). If the interface status is always down for a period, the system automatically stops the interface power and the system enters power-saving mode. They also support EEE energy feature, by which if a port stays idle for a period, the system will set the port to energy-saving mode. The switches are also compliant with material environmental protection and the EU RoHS safety standard.

Enhanced POE power

H3C IE4500-G series industrial switches support POE++(maximum 90W) power supply. The total PoE consumption reaches 360W, which can ensure the stable operation of various terminal equipment's that need POE power supply.

Fast PoE, perpetual PoE

Fast PoE: Typically, PIs (power interface) does not deliver power to PDs (powered device) the moment the PSE (power sourcing equipment) is powered on but wait until the PSE completes startup. Fast PoE enables PIs to deliver power to PDs within few seconds after power is supplied to the PSE.

Perpetual PoE: Perpetual PoE continuously monitors the PD states and ensures continued power supply to PDs even when the PSE device is hot rebooting.

PoE Watchdog: PoE watchdog function enables the adaptive monitoring network to have a “self-healing” function. When this function is turned on, the system can automatically detect the camera 24 hours. If the camera has no stream output, it is judged that the camera is crashed. The camera is restarted by cutting off the PoE power supply to solve the camera crashed problem. No manual operation is required, which can provide timely and reliable solutions for operation and maintenance.

Comprehensive authentication strategies

H3C IE4500-G series industrial switches support AAA, RADIUS authentication, user-based account, IP, MAC, VLAN and port based dynamic or static user identification and binding. The switches also support H3C iMC to implement real-time user management, diagnose and remove illicit network attack.
