S6720-32C-SI-AC

The Huawei S6720-32C-SI-AC is a high-performance, multi-gigabit fixed switch belonging to Huawei’s S6720-SI series. This series is designed to meet the demands of next-generation enterprise networks, providing high-speed access for a variety of devices, including modern wireless access points (APs) and 10GE servers in data centers. The “SI” denotes its “Standard Version” capabilities, offering a rich set of Layer 2 and Layer 3 features.

Here’s an introduction to its key characteristics:

Key Features:

• Multi-Gigabit Base-T Ports: This switch is distinguished by its 24 x 100M/1G/2.5G/5G/10G Base-T Ethernet ports (Multi-Gigabit ports). These versatile ports automatically negotiate the speed, making them ideal for connecting:
  • Next-generation wireless APs (e.g., Wi-Fi 6/6E) that require bandwidths beyond 1 Gigabit.
  • High-end workstations with multi-gigabit NICs.
  • Legacy devices that operate at 100M or 1G.
• 4 x 10GE SFP+ Fixed Ports: In addition to the Multi-Gigabit ports, it includes 4 x 10GE SFP+ ports. These are typically used for high-bandwidth uplinks to the aggregation or core layer of the network, or for connecting 10GE servers or storage.
• One Extended Slot: The presence of an extended slot provides flexibility for future expansion. This slot can typically accommodate various interface cards, such as:
  • 2-port 40GE QSFP+ interface card, providing powerful 40 Gigabit uplinks.
  • 4-port 10GE SFP+ interface card, for additional 10GE fiber connectivity.
• Built-in AC Power Supply: The “-AC” indicates that it comes with an integrated AC power module.
• Dual Pluggable Power Supplies: The switch supports two pluggable power supply slots, allowing for 1+1 power redundancy. This means you can install two AC or DC power modules (or a combination) to ensure continuous operation even if one power module fails.
• High Performance:
  • Switching Capacity: 2.56 Tbit/s (terabits per second). This high capacity ensures non-blocking, wire-speed forwarding for all its ports, even with a mix of multi-gigabit and 10GE traffic.
  • Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its efficient processing of a large volume of network traffic.
• Comprehensive Security Features: The S6720-32C-SI-AC integrates robust security measures to protect the network:
  • Defense against DoS, ARP, and ICMP flood attacks.
  • DHCP snooping, IP source check, and strict ARP learning to prevent IP/MAC spoofing and related attacks.
  • 802.1X authentication, centralized MAC address authentication, and portal authentication for stringent user and device access control.
  • CPU defense mechanisms to protect the control plane.
• Advanced Quality of Service (QoS): It provides sophisticated QoS mechanisms to prioritize critical services:
  • Traffic classification based on various criteria (e.g., 5-tuple, IP precedence, DSCP, VLAN ID, CoS).
  • Flow-based two-rate three-color CAR (Committed Access Rate).
  • Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to guarantee service quality for voice, video, and data.
• High Reliability: To maximize network uptime, it supports various redundancy and protection mechanisms:
  • STP/RSTP/MSTP for loop prevention.
  • RRPP, Smart Link, SEP, and G.8032 ERPS for millisecond-level protection switchover in various network topologies.
  • E-trunk for inter-device link aggregation and load balancing.
  • BFD (Bidirectional Forwarding Detection) for rapid fault detection.
• Flexible Management and iStack:
  • iStack Technology: This allows multiple physical switches to be virtualized into a single logical switch. This simplifies management, enhances scalability, and improves overall network resilience. Multi-Gigabit, 10GE SFP+, or 40GE QSFP+ (via extended slot) ports can be used as stack ports.
  • Supports various management interfaces, including CLI, Web-based NMS, and SNMPv1/v2c/v3.
  • Automated deployment features (e.g., automatic configuration, plug-and-play, USB-based deployment) and remote upgrades simplify operations.
• Layer 3 Routing Capabilities: As a “Standard Version” (SI) switch, it provides a comprehensive set of IPv4 and IPv6 routing protocols:
  • IPv4: Static, RIPv1/v2, OSPF, IS-IS, BGP, ECMP, VRRP, policy-based routing.
  • IPv6: Static, RIPng, OSPFv3, IS-ISv6, BGP4+, VRRP6.

Typical Applications:

• Multi-Gigabit Access for Wireless Networks: Ideal for providing high-speed connectivity to modern Wi-Fi 6/6E access points that require 2.5G, 5G, or even 10G Ethernet ports, removing network bottlenecks for wireless users.
• 10GE Server Access in Data Centers: Can function as an access switch in data centers, connecting 10GE servers and providing efficient data flow.
• Campus Network Access/Aggregation Layer: Suitable for the access or aggregation layer in enterprise or educational campus networks, supporting a mix of traditional and high-speed devices.

The S6720-32C-SI-AC is a robust and future-proof choice for organizations looking to build high-performance, secure, and scalable networks that can accommodate both current and next-generation connectivity requirements.
