S6720-56C-PWH-SI-AC

The Huawei S6720-56C-PWH-SI-AC is a powerful and versatile 10 Gigabit Ethernet (GE) fixed switch belonging to the S6720-SI series. It’s designed for high-performance enterprise campus networks, data center server access, and particularly excels at high-speed wireless device access due to its multi-gigabit and PoE++ capabilities. The “-AC” suffix signifies that it includes an AC (Alternating Current) power supply.

Here’s an introduction to its key features:

Key Features and Capabilities:

• Mixed Gigabit and Multi-Gigabit Base-T Ports with PoE++: This switch offers a diverse set of copper ports with PoE capabilities, providing flexibility for various device types:
  • 32 x 10/100/1000Base-T Ethernet ports (standard Gigabit Ethernet)
  • 16 x 100M/1G/2.5G/5G/10G Base-T Ethernet ports (multi-gigabit ports). These ports can auto-negotiate speeds, allowing for seamless upgrades to Wi-Fi 6/6E access points or other high-bandwidth devices without needing to replace existing cabling (Cat5e or higher for multi-gigabit).
  • All these copper ports support PoE++ (802.3bt), enabling them to provide up to 90W of power per port (depending on the power supply configuration). This is crucial for powering high-consumption devices like next-generation wireless APs, IP cameras, and video phones.
• 4 x 10GE SFP+ Fixed Uplink Ports: These ports provide high-bandwidth fiber connectivity for 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 modularity, allowing for future expansion with various interface cards, such as:
  • 2-port 40GE QSFP+ interface card, for extremely high-bandwidth uplinks.
  • 4-port 10GE SFP+ interface card, for additional 10GE fiber connectivity.
• Built-in AC Power Supply and Dual Pluggable Slots: The “-AC” indicates it comes with a pre-installed AC power supply. Furthermore, the switch supports two pluggable power supply slots, allowing for 1+1 power redundancy. This ensures continuous network operation and high availability, even if one power supply fails. You can configure it with two AC power modules for full redundancy.
• High Performance:
  • Switching Capacity: 2.56 Tbit/s (terabits per second). This high capacity ensures non-blocking, wire-speed forwarding across all its ports, accommodating demanding traffic loads.
  • Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its efficient processing of a large volume of network packets.
• Comprehensive Security Policies: The switch incorporates a wide array of security features to protect against various network threats:
  • Defense against DoS (Denial of Service), ARP, and ICMP flood attacks.
  • DHCP snooping, IP source check, and strict ARP learning to prevent unauthorized DHCP servers and IP/MAC spoofing.
  • 802.1X, MAC address authentication, and portal authentication for stringent user and device access control.
  • Port security and MAC address limits to prevent MAC address table exhaustion.
• Advanced QoS (Quality of Service): It offers sophisticated QoS mechanisms to ensure the prioritization of critical services:
  • 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 guarantee the performance of delay-sensitive services like voice and video.
• 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 MultiGE, 10GE SFP+, or 40GE QSFP+ (via extended slot) ports can be configured as stack ports.
  • 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.

Typical Applications:

• Next-Generation Wireless Access: The combination of multi-gigabit speeds and PoE++ makes it highly suitable for deploying and powering a large number of high-performance Wi-Fi 6/6E access points, eliminating bottlenecks in wireless networks.
• Converged Campus Network Access: Ideal for campus network access layers where a mix of traditional Gigabit Ethernet devices and newer multi-gigabit PoE-powered devices (IP phones, cameras, thin clients, modern PCs) need to be connected efficiently.
• Data Center Access: Can serve as an access switch for 10GE servers in data center environments, especially where PoE capabilities are also required for server management or other powered devices.

The S6720-56C-PWH-SI-AC is a robust and feature-rich switch, designed to meet the growing demands of modern networks for bandwidth, power, and intelligent management.
