Description

The Huawei S6720-16X-LI-16S-AC is a next-generation, simplified 10GE fixed switch from Huawei’s S6720-LI series. It’s designed to provide high-performance 10 Gigabit Ethernet access and can be utilized in various network environments, particularly as an access switch in campus networks and data center networks.

Hee’s an introduction to its key features and specifications:

Key Features:

  • High-Speed 10GE Access: It comes equipped with 16 x 10 Gigabit Ethernet (GE) SFP+ ports, offering line-rate 10GE access.
  • Uplink Capabilities: While its primary role is access, it supports 40GE uplink ports (though this specific model has 16 x 10GE SFP+ ports, other models in the S6720-LI series also offer 40GE QSFP+ uplink options).
  • Built-in AC Power: It features a built-in AC power supply and supports Redundant Power Supply (RPS) for enhanced reliability.
  • High Performance:
    • Switching Capacity: 1.28 Tbit/s
    • Packet Forwarding Rate: 240 Mpps
  • Comprehensive Security:
    • Supports various security features like DHCP snooping, strict ARP learning, centralized MAC address authentication, and 802.1X authentication.
    • Includes IP source check to prevent DoS attacks.
    • Can limit the number of MAC addresses learned on a port to prevent MAC address entry exhaustion.
  • Robust QoS: Supports traffic classification based on ACLs, 802.1p fields, VLAN IDs, source MAC addresses, and Ethernet types. It offers flow-based two-rate three-color CAR and multiple queue scheduling algorithms (WRR, DRR, PQ, WRR+PQ, DRR+PQ) to ensure quality for voice, video, and data services.
  • Management and Maintenance: Supports SNMPv1/v2/v3, CLI, Web NMS, NTP, SSH v2, HWTACACS, RMON, log hosts, and port-based traffic statistics.
  • Layer 3 Features: Provides IPv4 routing capabilities (Static routing, RIP, OSPF, VRRP, policy-based routing) and IPv6 routing (Static routing, RIPng).
  • VLAN Features: Supports 4K VLANs, Guest VLAN, voice VLAN, VLAN assignment based on various criteria, VLAN mapping, and QinQ.
  • Compact Design: Designed with a compact form factor for flexible deployment.

Typical Applications:

  • 10GE Access Layer in Campus Networks: Providing high-bandwidth connectivity for endpoints and servers within an enterprise campus.
  • Data Center Networks: Serving as an access switch in data center environments, supporting high-speed server connectivity.

In essence, the Huawei S6720-16X-LI-16S-AC is a powerful and versatile 10GE switch suitable for building scalable, reliable, manageable, and secure network infrastructures.

NOTE:

When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).

The equipment can operate beyond the normal operating temperature range for a short-term period, but the following conditions must be met:

  • The equipment operates at a temperature of over 45°C (113°F) consecutively for at most 96 hours in one year.
  • The equipment operates at a temperature of over 45°C (113°F) for a total of no more than 360 hours in one year.
  • The equipment operates at a temperature of over 45°C (113°F) for no more in 15 times in one year.

The equipment may be damaged or experience unexpected exceptions if any of the preceding limits is exceeded.

The equipment cannot start when the temperature is lower than 0°C (32°F). The maximum distance of optical modules used in these conditions cannot exceed 10 km.

Storage temperature -40°C to +70°C (-40°F to +158°F)
Noise under normal temperature (27°C, sound power) < 46.5 dB(A)
