S6720-32C-PWH-SI

The Huawei S6720-32C-PWH-SI is a next-generation multi-gigabit 10 Gigabit Ethernet (GE) fixed switch, part of Huawei’s S6720-SI series. This switch is designed for high-performance networking in various environments, including enterprise campus networks, data centers, and especially for supporting high-speed wireless devices.

The key aspects of this model are its multi-gigabit copper ports with PoE++, which makes it a powerful solution for modern network infrastructure.

Here’s a detailed introduction:

Key Features and Capabilities:

• 24 x 100M/1G/2.5G/5G/10G Base-T Ethernet Ports (Multi-Gigabit) with PoE++: This is the standout feature. These ports offer exceptional flexibility by automatically negotiating speeds from 100 Mbps up to 10 Gbps over standard copper cabling (Cat5e or higher for multi-gigabit speeds). Critically, they also support PoE++ (802.3bt), providing up to 90W of power per port. This makes it an ideal choice for:
  • Powering and connecting next-generation Wi-Fi 6/6E access points (APs) that require more than 1 Gigabit of bandwidth and significant power.
  • Connecting and powering other high-power PoE devices such as IP cameras, video surveillance systems, video phones, and thin clients.
• 4 x 10GE SFP+ Fixed Ports: These ports provide high-bandwidth fiber uplinks to connect to the aggregation or core layer of the network, or to 10GE servers or storage devices. They can also auto-sense for 1GE speeds.
• One Extended Slot: This slot provides modularity and flexibility, allowing for expansion with various interface cards, such as:
  • 2-port 40GE QSFP+ interface card, for even higher-bandwidth uplinks.
  • 4-port 10GE SFP+ interface card, for additional 10GE fiber connectivity.
• Dual Pluggable Power Supplies: The switch is designed with two power supply slots, supporting 1+1 power redundancy. This means you can install two power modules (AC or DC, depending on the specific power module purchased) to ensure continuous operation and high availability, even if one power supply unit fails. Note that the “S6720-32C-PWH-SI” model designation itself does not include a pre-installed power supply; you would order the specific AC or DC power modules separately (e.g., S6720-32C-PWH-SI-AC would come with an AC module).
• High Performance:
  • Switching Capacity: 2.56 Tbit/s (terabits per second). This ensures wire-speed, non-blocking forwarding for all ports, even under heavy traffic loads and with full PoE utilization.
  • Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its robust capability to process a high volume of network packets efficiently.
• Comprehensive Security: The switch is equipped with a wide range of security features to protect against various network threats:
  • Defense against DoS (Denial of Service), ARP, and ICMP attacks.
  • DHCP snooping, IP source check, and strict ARP learning to prevent IP/MAC spoofing.
  • 802.1X, MAC address authentication, and portal authentication for strong user and device access control.
  • CPU defense mechanisms to protect the switch’s control plane.
• Advanced Quality of Service (QoS): It offers sophisticated QoS mechanisms to prioritize critical services:
  • Traffic classification based on multiple 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 guarantee the performance of delay-sensitive services like voice and video.
• 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 network management, enhances scalability, and improves overall network resilience. Any MultiGE, 10GE SFP+, or 40GE QSFP+ (via extended slot) ports can be configured as stack ports.
  • Supports various management interfaces, including CLI, Web-based NMS, and SNMPv1/v2c/v3.
  • Features like automatic configuration, plug-and-play, USB-based deployment, and remote upgrades simplify operations and maintenance.
• 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:

• Next-Generation Wireless Access: This is a prime application, as its multi-gigabit PoE++ ports are perfectly suited for powering and connecting high-performance Wi-Fi 6/6E access points, eliminating bottlenecks in modern wireless networks.
• High-Density PoE Access: Ideal for campus network access layers where a large number of PoE-powered devices (e.g., IP phones, surveillance cameras, VDI thin clients) are deployed.
• 10GE Server Access in Data Centers: Can serve as an access switch for 10GE servers, providing high-speed connectivity and supporting PoE for server management or other powered devices in the rack.
• Campus Network Access/Aggregation Layer: It can function as a powerful access or light aggregation switch in enterprise or educational campus networks, supporting a mix of traditional and high-speed devices, and simplifying cabling with PoE.

The S6720-32C-PWH-SI is a robust and future-proof choice for building scalable, secure, and reliable high-performance networks, especially those embracing multi-gigabit wired and wireless technologies with PoE capabilities.
