The Huawei S6720-32X-SI-32S-AC is a powerful and versatile 10 Gigabit Ethernet (GE) fixed switch from Huawei’s S6720-SI series. The “SI” (Standard Version) indicates that it offers a comprehensive set of Layer 2 and Layer 3 features, making it suitable for a wide range of demanding enterprise and data center network applications.
Here’s a breakdown of its key characteristics:
Key Features:
- High-Density 10GE SFP+ Ports: It is equipped with 32 x 10GE SFP+ ports. This high port density makes it an excellent choice for connecting numerous high-bandwidth devices, such as:
- Servers in a data center (as an access switch).
- High-performance workstations in a campus network.
- Aggregating traffic from other access layer switches.
- These SFP+ ports are typically auto-sensing, allowing them to operate at 1GE speeds as well for backward compatibility.
- Built-in AC Power Supply: The “-AC” suffix denotes that it comes with an integrated AC power supply for straightforward deployment in environments with standard AC power.
- Dual Pluggable Power Supply Slots: The switch features two power supply slots, allowing for the installation of dual AC or DC power modules. This provides 1+1 power redundancy, a critical feature for ensuring high availability and continuous network operation in mission-critical environments.
- High Performance:
- Switching Capacity: 2.56 Tbit/s (terabits per second). This substantial capacity ensures non-blocking, wire-speed forwarding across all its high-density ports, even under heavy traffic loads.
- Packet Forwarding Rate: 240 Mpps (million packets per second). This indicates its robust capability to process a large volume of network packets efficiently.
- Comprehensive Security Policies: The switch incorporates a wide array of security features to protect the network from various attacks and unauthorized access:
- DoS, ARP, and ICMP Attack Defense: Protects against common network attacks like SYN flood, Land, Smurf, and ICMP flood.
- DHCP Snooping, IP Source Check: Prevents unauthorized DHCP servers, IP/MAC spoofing, and related man-in-the-middle attacks.
- 802.1X and MAC Address Authentication: Provides robust user and device access control, supporting various authentication methods (AAA, RADIUS, HWTACACS).
- Port Security: Limits the number of MAC addresses learned on a port to prevent MAC address table exhaustion.
- CPU Defense: Protects the switch’s control plane from excessive traffic.
- Advanced QoS (Quality of Service): It offers sophisticated QoS mechanisms to ensure the priority of critical applications:
- Traffic Classification: Based on multiple criteria (e.g., 5-tuple, IP precedence, DSCP, VLAN ID, CoS).
- CAR (Committed Access Rate): Flow-based two-rate three-color CAR for granular bandwidth control.
- Queue Scheduling Algorithms: Supports various algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to guarantee the performance of delay-sensitive services like voice and video.
- High Reliability: The switch supports various redundancy and protection mechanisms to maximize network uptime:
- STP/RSTP/MSTP: Standard Spanning Tree Protocols for loop prevention.
- RRPP, Smart Link, SEP, G.8032 ERPS: Advanced Ethernet protection technologies that provide fast (millisecond-level) switchover in ring or tree topologies, ensuring service continuity.
- E-trunk: Enhanced Trunk for inter-device link aggregation with load balancing.
- BFD (Bidirectional Forwarding Detection): For rapid fault detection with routing protocols.
- Flexible Management and iStack:
- iStack Technology: This allows multiple physical switches to be virtualized into a single logical switch, simplifying network management, increasing scalability, and enhancing network resilience. Any 10GE SFP+ port can be configured as a stack port (up to 16 physical ports in a stack).
- Supports various management interfaces, including CLI, Web-based NMS, and SNMPv1/v2c/v3.
- Features like automatic configuration, plug-and-play, USB-based deployment, and batch remote upgrades streamline operations and maintenance.
- Layer 3 Routing Capabilities: Provides a comprehensive set of IPv4 and IPv6 routing protocols, enabling efficient network segmentation and inter-VLAN routing:
- IPv4: Static, RIPv1/v2, OSPF, IS-IS, BGP, ECMP, VRRP, policy-based routing.
- IPv6: Static, RIPng, OSPFv3, IS-ISv6, BGP4+, VRRP6.
Typical Applications:
- High-Density 10GE Access: Its most common application is to provide high-density 10GE access for servers in data centers or for high-performance user groups and devices in campus networks.
- Campus Network Access/Aggregation Layer: It can function as a high-performance access switch or a light aggregation switch in enterprise or educational campus networks.
- Next-Generation Wireless Access: While this specific model features SFP+ ports (not Base-T Multi-Gigabit ports), other S6720-SI models offer Multi-Gigabit ports for connecting high-speed wireless access points (APs), and this switch could serve as an uplink/aggregation device for such deployments due to its 10GE capacity.
The “SI” (Standard Version) series generally offers a richer set of features, particularly in Layer 3 routing and advanced security, compared to the “LI” (Lite Version) series. The S6720-32X-SI-32S-AC is a robust choice for building scalable, secure, and reliable high-performance networks.
