S6700 Series 10G Switches

Huawei's S6700 Switches deliver high-performance 10 GE switching and forwarding; fully compatible with Huawei's Versatile Routing Platform software (VRP5), with built-in reliability and intelligent management features.

Advanced switching architecture and line-card buffering, with energy-efficient electronics and dynamic power management ensure smooth, sustained performance. Add capacity when and where needed - SFP+ fiber optic service ports and Huawei's iStack virtualization let you add ports and capacity in the same rack or another rack with no impact on the network or any user. Cost-effective fault tolerance - Integrated VRRP support lets you use two S6700 switches to ensure non-stop communications; ECMP support enables multiple equal-cost routes to upstream devices with automatic switching when an active route is unavailable.

Combine with Huawei S9700 or S7700 Routing Switches in large-scale enterprise campus environments, or use as a core switch in a smaller campus or branch offices. Supports wired and wireless application bandwidth needs.

Highly scalable 10 GE ports with comprehensive onboard management and security features make the S6700 a flexible switch for use as an access device or core switch in a campus network. Combine with Huawei S5700 Gigabit Switches for cost-effective, energy-efficient support of server-based applications.

Typical Deployment Scenarios

S6700 Switches Provide High-density 10 GE Server Access in an Internet Data Center

S6700 Switches in Redundant Configuration as Core Switches in an Enterprise Campus Network

Highlights – Features and Benefits

Build a high-density 10 GE network with resilient, rock-solid S6700 Series Switches

Large-capacity, high-density 10 Gbit/s access

S6700 delivers the highest density of all 10 GE ports and features the largest switching capacity among its counterparts. Each S6700 provides a maximum of 48 x 10 GE ports.

  • Provide 1 GE and 10 GE access
  • Automatically identifies optical module types, maximizing ROI and allowing users to flexibly deploy services.
  • Large buffering capacity and advanced scheduling to ensure non-block transmission during high data center traffic volume.

Comprehensive security policies

The S6700 provides multiple security measures to defend against Denial of Service (DoS) attacks, as well as attacks against networks or users.

  • Dynamic Host Configuration Protocol (DHCP) snooping, which discards invalid packets that do not match any binding entries, such as Address Resolution Protocol (ARP) and IP spoofing packets. Connect to a DHCP server to protect against bogus DHCP server attacks.
  • ARP learning support to prevent attacks that exhaust ARP entries.
  • Centralized MAC address authentication and 802.1x authentication.

High-reliability mechanisms

The S6700 supports redundant power supplies. Choose single or double power supplies, or use S6700 Switches to optimize reliability. With two fans, the S6700 has a longer MTBF time than counterpart switches.

  • Enhanced Trunk (E-Trunk) support. In redundant configuration, E-Trunk protects the links between Customer Edge (CE) and Provider Edge (PE) systems and provides backup between the PEs. E-trunk enhances link reliability between devices.
  • Smart Ethernet Protection (SEP) protocol – a ring network protocol applied to the link layer on an Ethernet network.
  • Ethernet Ring Protection Switching (ERPS), also referred to as G.8032 – supports various services and allows flexible networking, helping customers build a network with lower OPEX and CAPEX.
  • Virtual Router Redundancy Protocol (VRRP) – provides reliable, non-stop communications. Multiple equal-cost routes to upstream devices provide route redundancy. When an active route is unreachable, traffic is switched to a backup route.

Enhanced QoS control mechanism

The S6700 implements complex traffic classification based on packet information, such as the 5-tuple, IP preference, ToS, DSCP, IP protocol type, ICMP type, TCP source port, VLAN ID, Ethernet protocol type, and CoS. Access Control Lists (ACLs) can be applied to inbound or outbound directions on an interface.

High scalability

Huawei iStack technology allows switches that are far apart to form a stack. Configure a port on the S6700 as a stack port; the distance between stacked switches can be further increased when the switches are connected with optical fibers.

Convenient management

The S6700 supports automatic configuration, plug-and-play deployment using a USB flash drive, and batch remote upgrades. These capabilities simplify device management and maintenance, and reduce maintenance costs.

  • SNMP v1/v2/v3 provides flexible methods for managing devices – Command Line Interface (CLI) and web-based Network Management System (NMS).
  • Network Quality Analyzer (NQA) for network planning and upgrades.
  • NTP, SSH v2, HWTACACS, RMON, log hosts, and port-based traffic statistics.
  • GARP VLAN Registration Protocol (GVRP) for dynamic provisioning of VLAN attributes to reduce network administrator workloads and ensure correct VLAN configuration.
  • Multiplex VLAN (MUX VLAN) for isolating Layer 2 traffic between interfaces in a VLAN.
  • Bidirectional Forwarding Detection (BFD) provides millisecond-level fault detection for protocols, such as OSPF, IS-IS, VRRP, and PIM, to improve network reliability.

Various IPv6 features

The S6700 supports IPv4/IPv6 dual stack and can migrate from an IPv4 network to an IPv6 network.

  • IPv4/IPv6 dual stack, IPv6 over IPv4 tunnels (including manual tunnels, 6to4 tunnels, and ISATAP tunnels), and Layer 3 line-speed forwarding.
  • IPv6 routing protocols including RIPng and OSPFv3.
