S6720-30L-HI-24S

The Huawei S6720-30L-HI-24S is a high-end 10 Gigabit Ethernet (GE) fixed switch, part of Huawei’s S6720-HI series. The “HI” (High-End Version) designation signifies that this is the most advanced and feature-rich variant within the S6720 line, offering a fully programmable architecture and advanced capabilities for intelligent networks, making it suitable for demanding enterprise campus, carrier, university, and government networks.

The “L” in “30L-HI” might indicate a specific hardware variant or form factor, but the core “HI” features are the defining aspect.

Here’s an introduction to its key features and typical applications:

Key Features:

• Diverse High-Speed Port Configuration: This switch offers a powerful combination of optical ports:
  • 24 x 10GE SFP+ ports: Provides high-density 10 Gigabit Ethernet connectivity, ideal for connecting servers, high-performance workstations, or for aggregating traffic from access layer switches. These ports support auto-negotiation down to 1GE speeds.
  • 4 x 40GE QSFP+ ports: Offers substantial bandwidth for uplinks to the core or aggregation layer. Each 40GE QSFP+ port can typically be broken out into four 10GE SFP+ ports, providing additional 10GE flexibility if needed.
  • 2 x 100GE QSFP28 ports: This is a major highlight of the HI series. These two 100 Gigabit Ethernet ports provide incredibly high-bandwidth uplinks to the network core, spine layer in data centers, or for inter-switch links where massive throughput is required.
• Dual Pluggable Power Supply Slots: The switch supports two pluggable power supply slots, allowing for 1+1 power redundancy. This ensures maximum availability and continuous network operation, as the switch can function even if one power supply fails. Power modules (e.g., 600W AC or 350W DC) are sold separately.
• No Extended Slots: Similar to some other fixed S6720 models, this specific model has a fixed port configuration and does not support additional extended slots.
• Superior Performance:
  • Switching Capacity: 2.56 Tbit/s (Terabits per second). This ensures wire-speed, non-blocking forwarding across all its ports, even under the most demanding traffic conditions.
  • MAC Address Table: Supports a large MAC address table (e.g., 64K MAC address entries), suitable for extensive network deployments.
• Intelligent Network Capabilities (HI Features – “IDN-Ready”):
  • Native Wireless AC Function: A standout feature of the HI series is its integrated Wireless Access Controller (AC) capabilities. This switch can natively manage up to 1,000 Access Points (APs), significantly reducing the need for standalone AC hardware and simplifying wireless network deployment and management. The wireless forwarding performance can reach up to 668 Gbit/s.
  • Super Virtual Fabric (SVF): This allows for network virtualization, where the entire network (core/aggregation, access switches, and APs) can be virtualized into a single “super switch.” This vastly simplifies network management, configuration, and O&M.
  • Free Mobility: Enables consistent user experience regardless of location, supporting policies that follow users across the network.
  • VXLAN Support: Supports Virtual Extensible LAN (VXLAN) to implement network virtualization, crucial for building agile and scalable cloud-ready data center networks and campus networks. It can support both centralized and distributed VXLAN gateway deployment and BGP EVPN for dynamic tunnel establishment.
  • Intelligent O&M with Telemetry and iPCA: Supports advanced monitoring technologies like Telemetry for real-time device data collection and iPCA (Packet Conservation Algorithm for Internet) for granular, real-time network quality monitoring and precise fault location without dedicated probes or simulated traffic.
  • Built-in Security Probes: Includes capabilities for abnormal traffic detection, Encrypted Communications Analytics (ECA) to identify malicious encrypted traffic, and network-wide threat deception (honeypot functionality) for enhanced security.
  • IEEE 1588v2 Protocol Support: For low-cost, high-precision, and high-reliability time and clock synchronization, essential for industries like power and transportation.
• Comprehensive Security Policies: Extends upon the EI series with even more robust security measures:
  • Defense against various DoS attacks, ARP, and ICMP flood attacks.
  • DHCP snooping, IP source guard, strict ARP learning.
  • 802.1X, MAC address authentication, portal authentication.
  • MACsec (Media Access Control Security) for hardware-based encryption of Ethernet frames.
  • CPU defense mechanisms, blacklists/whitelists, attack source tracing.
• Advanced Quality of Service (QoS): Provides sophisticated QoS to guarantee performance for critical applications:
  • Flexible traffic classification, policing, shaping.
  • Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) and WRED for congestion avoidance.
• High Reliability: Designed for maximum network uptime:
  • 1+1 power redundancy, hot-swappable power and fan modules.
  • Extensive set of redundancy protocols: STP/RSTP/MSTP, RRPP, Smart Link, SEP, G.8032 ERPS for millisecond-level protection.
  • E-trunk for inter-device link aggregation and BFD for rapid fault detection.
• Flexible Management and iStack:
  • iStack Technology: Allows multiple physical switches to be virtualized into a single logical switch for simplified management and enhanced scalability. Any 10GE SFP+, 40GE QSFP+, or 100GE QSFP28 ports can be configured as stack ports.
  • Supports CLI, Web-based NMS, SNMP, and cloud-based management.

Typical Applications:

• Large-Scale Enterprise Campus Core/Aggregation: The S6720-30L-HI-24S is ideal as a core or aggregation switch in very large and demanding campus networks, providing high-density 10GE access, and crucial 40GE and 100GE uplinks to the backbone.
• Data Center Access/Spine: Can serve as a high-performance access switch for 10GE servers or even as a compact spine switch in smaller to medium-sized data center fabrics, utilizing the 40GE and 100GE ports for inter-switch connectivity.
• Wired and Wireless Convergence: Its native AC capabilities make it a strong choice for environments that aim to converge wired and wireless networks onto a single platform, simplifying management and reducing CAPEX.
• Carrier Networks/Higher Education/Government: Its robust features, high performance, and advanced security make it suitable for various segments of carrier networks, as well as large university and government networks requiring high reliability and intelligent management.

In essence, the S6720-30L-HI-24S is a state-of-the-art fixed switch designed for future-proof networks that demand not just high bandwidth, but also intelligent operations, enhanced security, and seamless wired-wireless convergence.
