S6720-26Q-SI-24S-AC

The Huawei S6720-26Q-SI-24S-AC is a cutting-edge 10 Gigabit Ethernet (GE) fixed switch from Huawei’s S6720-SI series. It’s designed for high-performance networking in various scenarios, including enterprise campus networks, data centers, and for connecting high-speed wireless devices.

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

Core Specifications:

• 24 x 10GE SFP+ Ports: This provides a high density of 10 Gigabit Ethernet ports, suitable for connecting a large number of servers, high-performance workstations, or for acting as an access layer switch for other network devices. These ports typically support auto-sensing for GE speeds as well, offering deployment flexibility.
• 2 x 40GE QSFP+ Uplink Ports: The inclusion of two 40 Gigabit Ethernet QSFP+ ports provides high-bandwidth uplinks to connect to the aggregation or core layer of the network. Each 40GE QSFP+ port can typically be split into four 10GE SFP+ ports using breakout cables, effectively expanding the 10GE port count if needed.
• Built-in AC Power Supply: The “-AC” in the model name signifies that it comes with an integrated AC power module, simplifying power setup.
• Dual Pluggable Power Supplies: The switch supports dual pluggable power supplies, which can be AC or DC, for 1+1 power redundancy, ensuring high availability and continuous operation even if one power supply fails.
• High Performance:
  • Switching Capacity: 2.56 Tbit/s (terabits per second), indicating its ability to handle a massive amount of data traffic without bottlenecks.
  • Packet Forwarding Rate: 240 Mpps (million packets per second), demonstrating its efficient processing of network packets at line rate.

Key Features and Applications:

• Versatile High-Speed Access: It’s designed to offer high-speed access for both traditional wired devices requiring 10GE connectivity and next-generation high-speed wireless devices (like those supporting 802.11ac and beyond) where 2.5G/5G/10G Base-T ports might be present on other S6720-SI models, but for this specific model, the focus is on SFP+ for 10GE.
• Campus Network Access/Aggregation: Ideal for the access or aggregation layer in large campus networks, providing high-bandwidth connections to user devices and facilitating efficient data flow between different parts of the network.
• Data Center Server Access: Well-suited for the access layer within data centers, connecting racks of 10GE servers and ensuring rapid and reliable data exchange.
• Comprehensive Security: The switch incorporates a range of security features to protect against various network threats:
  • Defense against DoS (Denial of Service), ARP, and ICMP attacks.
  • DHCP snooping to prevent unauthorized DHCP servers and IP/MAC spoofing.
  • 802.1X and centralized MAC address authentication for stringent user access control.
  • Port security and MAC address limits to prevent MAC address table exhaustion.
• Advanced QoS (Quality of Service): It supports robust QoS mechanisms to prioritize critical services like voice and video:
  • Traffic classification based on various criteria (e.g., 5-tuple, IP precedence, DSCP, VLAN IDs).
  • Flow-based two-rate three-color CAR (Committed Access Rate).
  • Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to ensure service quality.
• High Reliability: To maximize network uptime, it supports numerous redundancy protocols:
  • 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 rapid protection switchover in various network topologies.
  • Enhanced Trunk (E-trunk) for inter-device link aggregation and load balancing.
• Flexible Management and iStack:
  • iStack Technology: This allows multiple physical switches to be virtualized into a single logical switch, simplifying management, enabling scalability, and improving overall network resilience. Any 10GE SFP+ or 40GE QSFP+ port can be configured as a stack port.
  • Supports various management interfaces, including CLI, Web NMS, and SNMPv1/v2/v3, for versatile network administration.
  • Features like automatic configuration, plug-and-play, USB-based deployment, and remote upgrades simplify operations and maintenance.
• Layer 3 Routing Capabilities: Provides comprehensive IPv4 routing (Static, RIP, OSPF, IS-IS, BGP, VRRP, policy-based routing) and IPv6 routing (Static, RIPng, OSPFv3, BGP4+, ISISv6) for efficient network segmentation and inter-VLAN communication.

The “SI” in the model name (Standard Version) indicates that it offers a rich set of Layer 2 and basic Layer 3 features, suitable for a wide range of enterprise and data center networking requirements, distinguishing it from the “LI” (Lite Version) which might have a more limited feature set.
