Product Characteristics

Product Characteristics

The S9300&S9300E series switches are used to access, aggregate, and transmit services across a MAN. The switches provide line-rate Fast Ethernet (FE), Gigabit Ethernet (GE), 10GE, 40GE, and 100GE interfaces. They can be deployed in enterprise networks and data centers, providing high-density interfaces and extensive value-added services (VASs).


100GE interfaces are available in V200R008C00 and later versions.

The S9300&S9300E come in the following models: S9303, S9306, S9310, S9312 and S9303E, S9306E, and S9312E. The S9303/S9303E, S9306/S9306E, S9310, and S9312/S9312E support a maximum of 3, 6, 10, and 12 line processing units (LPUs), respectively.

Using Huawei's Versatile Routing Platform (VRP) operating system and hardware-based forwarding and non-blocking data switching technology, the S9300&S9300E series switches provide carrier-grade reliability, line-rate forwarding capability, Quality of Service (QoS), service processing capabilities, and scalability. The S9300 provides extensive value-added service features, including firewall, Network Address Translation (NAT), network traffic analysis, IPSec VPN, load balancing, and WLAN AC.


The release in Russia does not provide IPSec VPN.

V200R003C00 and later versions do not provide the WLAN AC function.

V200R009C00 and later versions do not provide the firewall, Network Address Translation (NAT), network traffic analysis, IPSec VPN, or load balancing function.

In addition, the S9300&S9300E series switches have versatile network access capabilities in Layer 2 switching and Ethernet over MultiProtocol Label Switching (EoMPLS) services, and support IP services, broadband access, triple play, IP leased line, and VPN services. S9300&S9300E series switches also work together with other S series switches as well as Huawei NE80E, NE40E, ME60, and MA5200G to set up hierarchical metro Ethernet networks.


System extensibility includes:
  • Service extensibility: The SRU supports FSUA, which allows for future service development.

  • Power supply: For the S9300&S9300E, the maximum power of AC power supply modules is 2200 W, and the maximum power of DC power supply modules is 2400 W.

    Three types of PoE power supply modules are available: 800 W, 2200 W AC, and 2200 W DC.


    The S9310 and S9300E series switches do not support PoE function.

Powerful Forwarding Capabilities

On the S9300&S9300E, the hardware carries out two-level packet replication when forwarding multicast packets. That is, the SFU replicates multicast packets to the LPU, and the LPU's forwarding engine replicates the multicast packets to its interfaces.
