S6720S-32X-LI-32S-AC

The Huawei S6720S-32X-LI-32S-AC is a high-density, 10 Gigabit Ethernet (GE) fixed switch from Huawei’s S6720-LI and S6720S-LI series. It’s designed to provide robust and scalable access layer connectivity for demanding network environments like enterprise campus networks and data centers.

Here’s an introduction to its key features:

Core Specifications:

• 32 x 10GE SFP+ Ports: This is its most prominent feature, offering a high port density of 10 Gigabit Ethernet SFP+ ports. This allows for extensive high-speed connectivity to numerous servers, workstations, or other network devices requiring significant bandwidth. These ports typically support auto-sensing for GE speeds as well, providing deployment flexibility.
• Built-in AC Power Supply: The “-AC” in the model name indicates that it includes a built-in AC power module, simplifying power deployment.
• Redundant Power Supply (RPS) Support: For enhanced reliability and uninterrupted operation, the switch supports an external Redundant Power Supply (RPS) unit (e.g., Huawei RPS1800). This provides power redundancy in case of a single power supply failure.
• High Performance:
  • Switching Capacity: 1.28 Tbit/s (terabits per second), ensuring non-blocking, wire-speed forwarding across all its ports.
  • Packet Forwarding Rate: 240 Mpps (million packets per second), demonstrating its capability to process a high volume of network traffic efficiently.

Key Capabilities and Applications:

• High-Density 10GE Access: Its primary role is to provide high-bandwidth access in environments where many devices require 10GE connectivity.
• Campus Networks: Ideal for the access layer of large campus networks, delivering high-speed connections to user devices, servers, and departmental aggregation points.
• Data Center Networks: Well-suited for the access layer within data centers, connecting racks of 10GE servers and ensuring rapid data exchange.
• Comprehensive Security: The switch is equipped with various security features to protect against common network threats, including:
  • 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 strict user access control.
  • Port security and MAC address limits to mitigate MAC address table exhaustion attacks.
• Advanced QoS (Quality of Service): It supports sophisticated QoS mechanisms to ensure the priority of critical applications like voice and video:
  • Traffic classification based on various criteria (e.g., ACLs, 802.1p, VLAN IDs, MAC addresses).
  • Flow-based two-rate three-color CAR (Committed Access Rate).
  • Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ).
• High Reliability: To ensure network uptime, it supports various 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 fast protection switchover in various topologies.
  • Enhanced Trunk (E-trunk) for inter-device link aggregation and load balancing.
• Flexible Management:
  • iStack Technology: Allows multiple physical switches to be virtualized into a single logical switch, simplifying management and enabling scalability. Any 10GE SFP+ port can be configured as a stack port.
  • Supports various management interfaces including CLI, Web NMS, and SNMPv1/v2/v3.
  • Features like automatic configuration, plug-and-play, USB-based deployment, and remote upgrades simplify operations and maintenance.
• Layer 3 Routing: Provides essential IPv4 routing (Static, RIP, OSPF, VRRP, policy-based routing) and IPv6 routing (Static, RIPng, OSPFv3) for network segmentation and efficient inter-VLAN communication.

The “S” in S6720S-32X-LI-32S-AC often denotes a slightly simplified or specific variant compared to the S6720-32X-LI-32S-AC, but generally, they share core characteristics as high-performance 10GE access switches.
