Specifications

Designed for harsh environments and wide operating temperatures
Built with highly reliable industrial-grade components
Integrates switching, routing, ring network protection and security functions, with full Layer 2 Ethernet features and support for VLANs, QoS and flow control protocols
Supports STP/RSTP/MSTP for network loop prevention
Supports IPv4 and IPv6, static routing, RIP and OSPF, as well as network services such as DHCP and DNS
Supports RRPP (Rapid Ring Protection) protocol, which offers fast topology convergence and load balancing on Ethernet rings, improving bandwidth utilization
Implements comprehensive Ethernet security features, including port-based access control, 802.1x authentication, and ACL mechanisms for protection against ARP and DoS attacks
Also supports Ethernet Ring Protection Switching (ERPS), a ring network protection protocol that prevents broadcast storms and quickly restores communication in the event of link disconnection
Supports IRF2 technology, which allows multiple physical devices to be connected into a single logical device, simplifying management, improving system performance and reliability through link virtualization and aggregation
supports telemetry technology, allowing real-time information and alarms to be sent to an operation and maintenance platform for network analysis and optimization
Supports AAA and RADIUS authentication, dynamic or static user identification and binding, and real-time management with H3C iMC to diagnose and eliminate illicit network attacks
Offers a variety of management interfaces, including SNMP, iMC, CLI, Web-based, TELNET and FTP, with SSH2.0 and SSL encryption for added security
Provides redundant power supply and supports power failure based alarms
Supports IEEE Dying Gasp to generate an alarm in the event of power failure
