The Huawei S6720-32X-LI-32S-AC is a highly capable 10 Gigabit Ethernet (GE) fixed switch, part of Huawei’s S6720-LI series. It’s designed to meet the demanding requirements of modern campus networks and data centers, serving primarily as a high-density 10GE access switch.
Here’s an introduction to its key characteristics:
Core Features and Capabilities:
- High-Density 10GE Ports: The most significant feature is its 32 x 10GE SFP+ ports. This provides substantial connectivity for numerous 10GE-capable devices, such as servers, high-performance workstations, or aggregation points for other access switches.
- Built-in AC Power with RPS Support: It comes with a built-in AC power supply, and for enhanced reliability and continuous operation, it supports a Redundant Power Supply (RPS) connection (e.g., to an RPS1800). This ensures power redundancy in case of a power module failure.
- Impressive Performance:
- Switching Capacity: 1.28 Tbit/s (terabits per second). This high capacity allows for non-blocking, wire-speed forwarding across all ports.
- Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its ability to process a large volume of network traffic efficiently.
- Versatile Network Applications:
- Campus Networks: Ideal as an access switch for providing high-bandwidth connectivity to end-user devices, servers, and other network components within a large enterprise or campus environment.
- Data Center Networks: Well-suited for deployment at the access layer of data centers, connecting high-density 10GE servers and enabling fast data transfer within the data center fabric.
- Comprehensive Security Features: The switch incorporates robust security measures to protect the network from various threats. This includes:
- Defense against DoS (Denial of Service), ARP (Address Resolution Protocol), and ICMP (Internet Control Message Protocol) attacks.
- DHCP snooping to prevent unauthorized DHCP servers and IP/MAC spoofing attacks.
- Support for 802.1X authentication, centralized MAC address authentication, and port security to control user access.
- Ability to limit the number of MAC addresses learned on a port to prevent MAC address table exhaustion attacks.
- Advanced QoS (Quality of Service): It offers sophisticated QoS mechanisms to prioritize critical traffic. This includes:
- Traffic classification based on various criteria (ACLs, 802.1p, VLAN IDs, MAC addresses, etc.).
- Flow-based two-rate three-color Committed Access Rate (CAR).
- Multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to guarantee the quality of voice, video, and data services.
- High Reliability:
- Supports various Spanning Tree Protocol (STP) versions (STP, RSTP, MSTP) for loop prevention and redundancy.
- Features like RRPP (Rapid Ring Protection Protocol), Smart Link, SEP (Smart Ethernet Protection), and G.8032 ERPS (Ethernet Ring Protection Switching) for fast protection switchover in ring or tree topologies, ensuring network uptime.
- Supports Enhanced Trunk (E-trunk) for inter-device link aggregation and load balancing.
- Flexible Management and Maintenance:
- Supports iStack technology, allowing multiple switches to be virtualized into a single logical switch, simplifying management and providing scalability.
- Offers various management interfaces including CLI, Web NMS, SNMPv1/v2/v3.
- Supports features like automatic configuration, plug-and-play, USB-based deployment, and remote upgrades for ease of management.
- Includes network diagnostic tools like Virtual Cable Test (VCT) and Ethernet OAM.
- Layer 3 Routing Capabilities: Provides IPv4 routing (Static, RIP, OSPF, VRRP, policy-based routing) and IPv6 routing (Static, RIPng, OSPFv3) for greater network flexibility and scalability.
In summary, the Huawei S6720-32X-LI-32S-AC is a robust, high-performance 10GE access switch designed for modern networks that require high port density, strong security, advanced QoS, and reliable operation for demanding applications.
