S6720-26Q-LI-24S-AC

The Huawei S6720-26Q-LI-24S-AC is a member of Huawei’s S6720-LI series, which are next-generation simplified 10GE fixed switches. This particular model stands out by combining high-density 10GE access with convenient 40GE uplink capabilities, making it a versatile choice for modern network architectures.

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

Key Features:

• Mixed Port Density:
  • 24 x 10GE SFP+ ports: These provide ample high-speed connectivity for a large number of 10 Gigabit Ethernet devices, such as servers, high-performance workstations, or downstream access switches. These ports can often auto-sense and operate at GE speeds as well, offering deployment flexibility.
  • 2 x 40GE QSFP+ ports: These two 40 Gigabit Ethernet ports serve as powerful uplinks, allowing the switch to connect to the core or aggregation layer of a network with high bandwidth. Importantly, each 40GE QSFP+ port can typically be split into four 10GE ports, offering further flexibility in connecting to other 10GE devices if needed.
• Built-in AC Power with RPS Support: It comes with an integrated AC power supply and supports connection to an external Redundant Power Supply (RPS) for enhanced power reliability and continuous operation, crucial for critical network services.
• High Performance:
  • Switching Capacity: 1.28 Tbit/s (terabits per second). This ensures non-blocking, wire-speed forwarding across all its high-density ports.
  • Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its strong capability to process a large volume of network traffic efficiently.
• Comprehensive Security Policies: The switch incorporates a wide array of security features to protect the network from various attacks, including:
  • Defense against DoS (Denial of Service), ARP, and ICMP flood attacks.
  • DHCP snooping to prevent unauthorized DHCP servers and IP/MAC spoofing.
  • 802.1X authentication and centralized MAC address authentication for strict user access control.
  • Port security and MAC address learning limits to prevent malicious MAC address table exhaustion.
• Advanced QoS (Quality of Service): It provides robust QoS mechanisms to ensure the priority of critical applications:
  • Traffic classification based on various criteria (e.g., 5-tuple, IP preference, DSCP, VLAN ID).
  • Flow-based two-rate three-color Committed Access Rate (CAR).
  • Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to guarantee the performance of voice, video, and data services.
• High Reliability: Supports various redundancy protocols and technologies to ensure network uptime, such as:
  • STP/RSTP/MSTP for loop prevention.
  • RRPP (Rapid Ring Protection Protocol), Smart Link, SEP (Smart Ethernet Protection), and G.8032 ERPS (Ethernet Ring Protection Switching) for fast protection switching in various network topologies.
  • Enhanced Trunk (E-trunk) for inter-device link aggregation.
• Flexible Management and Maintenance:
  • Supports iStack technology, allowing multiple switches to be virtualized into a single logical device for simplified management and increased network scalability.
  • Offers various management interfaces (CLI, Web NMS, SNMPv1/v2/v3).
  • Supports automatic configuration, plug-and-play, USB-based deployment, and batch remote upgrades.
  • Includes network diagnostic tools like Virtual Cable Test (VCT) and Ethernet OAM.
• Layer 3 Routing: Provides essential IPv4 routing capabilities (Static, RIP, OSPF, VRRP, policy-based routing) and IPv6 routing (Static, RIPng, OSPFv3) for network segmentation and inter-VLAN routing.

Typical Applications:

• 10GE Access Layer in Campus Networks: This is a primary application, providing high-bandwidth access for servers, power users, and other network devices within an enterprise or educational campus. The 40GE uplinks connect efficiently to the campus aggregation or core layer.
• Data Center Networks (Access Layer): It can serve as a crucial access switch in data centers, providing high-speed connectivity to racks of 10GE servers and utilizing the 40GE ports for high-capacity uplinks to the data center’s spine or aggregation switches.

In summary, the Huawei S6720-26Q-LI-24S-AC is a robust, high-performance, and feature-rich 10GE switch with valuable 40GE uplink capabilities, making it an excellent choice for demanding access layer deployments in both campus and data center environments.
