Utilizing next-generation high-performance hardware and Huawei Versatile Routing Platform(VRP) software, the S3300 supports enhanced selective QinQ, line-speed cross-VLAN multicast duplication, and Ethernet OAM. It also supports carrier-class reliability networking technologies including Smart Link (applicable to tree networks) and RRPP (applicable to ring networks). The S3300 can be used as an access device in a building or a convergence and access device on a campus network. The S3300 supports easy installation, automatic conguration, and plug-and-play, which dramatically reduces the network deployment cost of customers.The S3300 is a case-shaped device with a 1 U high chassis, provided in a standard version (SI), an enhanced version (EI), and an advanced version (HI). SI supports Layer-2 functions and basic Layer-3 functions. EI supports complex routing protocols and abundant features. HI supports higher-specication MAC addresses, routes, and multicast table entries, and more powerful hardware capabilities.
Product Features ,Powerful Surge Protection
The S3300 adopts the Huawei patented built-in surge protection technology that can effectively defend against lightning induced over-voltage. Each port has a surge protection capability of 6 KV. Compared with the conventional surge protection design, the Huawei patented surge protection technology greatly reduces the possibility of lightning damage on the device in severe environments or even in scenarios where grounding cannot be implemented.Unique Fan-Free Design
In the S3300 series, three non-PoE models that have 24 electrical ports adopt a fan-free design, which dramatically reduces the power consumption and noise of the device. In addition, this design reduces mechanical faults and protects the device against damages caused by condensed water and dust.
The S3300 adopts next-generation highly-integrated chips and power-saving circuit design to ensure even heat dissipation. It also supports idle port sleep to further reduce power consumption.
The S3300 emits low radiation and complies with the radiation standards of electric appliances, so it has no harm to human body and is more environmentally friendly.Powerful Service Support
The S3300 supports enhanced selective QinQ by using chips. This function adds outer VLAN tags to packets without occupying ACL resources to support multi-service provisioning.
The S3300 supports 1,024 multicast groups (the 33HI supports 2,048 multicast groups) and protocols including IGMP snooping, IGMP lter, IGMP fast leave, and IGMP proxy. The S3300 supports line-speed cross-VLAN multicast replication, multicast load balancing among bundled ports, and controllable multicast, meeting requirements for IPTV and other multicast services.
The S3300 supports Multi-VPN-Instance CE (MCE) to isolate users of different VPNs on a device, ensuring user data security and reducing customer expenditures.
Multiple models of the S3300 support PoE and comply with IEEE 802.3af and 802.3at (PoE+). By using this function, the S3300 can supply power over the Ethernet to the connected standard PDs such as IP Phones,WLAN APs, and Bluetooth APs. Each port can provide up to 30 W of power. This reduces the power cable layout and management cost for terminal devices. The S3300 can also be congured to provide power for PDs at specied time as required.Security and QoS
The S3300 provides various security protection measures. It can defend against Denial of Service (DoS) attacks, attacks to networks, and attacks to users. DoS attacks include SYN Flood attacks, Land attacks, Smurf attacks, and ICMP Flood attacks. Attacks to networks refer to STP BPDU/root attacks. Attacks to users include bogus DHCP server attacks, man-in-the-middle attacks, IP/MAC spoong attacks, DHCP request ood attacks, and DoS attacks by changing the CHADDR eld of packets.Product Brochure Qu di way® S3300 Switches
The S3300 listens to the MAC/IP address, address lease, VLAN ID, and port number about a DHCP user by establishing and maintaining a DHCP snooping binding table. In this way, IP addresses and access ports of DHCP users can be tracked. The S3300 directly discards invalid packets that do not match binding entries, such as ARP spoong packets and packets with bogus IP addresses, to prevent hackers or attackers from initiating man-inthe-middle attacks to campus networks by using ARP packets. The trusted port feature of DHCP snooping is used to ensure the validity of the DHCP server.
The S3300 supports strict ARP learning to prevent ARP spoong attackers from exhausting ARP entries so that authorized users can connect to the Internet. It also supports IP source check to prevent DoS attacks caused by MAC address spoong, IP address spoong, and MAC/IP address spoong. The URPF function provided by the S3300 can check packet transmission paths to authenticate the packets received, which can protect the network against the spread of source address spoong attacks.
The S3300 supports centralized MAC address authentication and 802.1x authentication. User information such as the user account, IP address, MAC address, VLAN ID, access port number, and ag indicating whether antivirus software is installed on the client can be bound statically or dynamically, and user policies (VLAN, QoS,and ACL) can be delivered dynamically.
The S3300 can limit the number of source MAC addresses learned on a port to prevent attackers from exhausting MAC address entries by using bogus source MAC addresses. In this way, MAC addresses of authorized users can be learned and ooding is prevented.
The S3300 can implement complex trafc classication based on information such as the ve-tuple, IP priority,ToS, DSCP, IP protocol type, ICMP type, TCP source port number, VLAN ID, Ethernet frame protocol type, and CoS. The S3300 supports inbound and outbound ACLs. The S3300 supports ow-based two-rate three-color CAR. Each port supports eight priority queues, WRED congestion prevention mechanism, and multiple queuescheduling algorithms such as WRR, DRR, SP, WRR+SP, and DRR+SP. This ensures the quality of voice, video and data services.
Good Expandability and High Reliability
The S3300 switches support Intelligent Stacking (iStack) and plug-and-play. Multiple S3300s start to construct a virtual switch automatically after being connected by stacking cables. Stacked switches are classied into active, standby, and slave switches. After a standby switch is congured, the duration of service interruption caused by faults on the active switch is reduced. The S3300 supports intelligent upgrade, freeing customers from upgrading the software version of a switch after adding the switch to a stack. Utilizing the iStack technology, multiple switches can be interconnected to expand the system capacity and can be managed by using a single IP address,which greatly reduces the cost of system expansion, operation, and maintenance. Compared with traditional networking technologies, iStack has advantages in expansibility, reliability, and system architecture.Product Brochure

Besides the traditional STP, RSTP, and MSTP, the S3300 supports enhanced Ethernet reliability technologies such as Smart Link (applicable to tree networks) and RRPP (applicable to ring networks), which implements millisecond-level protective link switchover and ensures network reliability. In addition, the S3300 supports multi iinstance for Smart Link and RRPP to implement load balancing among links, further improving bandwidth usage.
The S33HI supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer of an Ethernet network. SEP is applicable to open ring networks and can be deployed independently from the upper-layer aggregation devices to provide millisecond-level switchover without interrupting services. SEP features simplicity, high reliability, high switchover performance, convenient maintenance, and exible topology,enabling customers to manage and deploy networks conveniently.Considerate Maintenance-Free and Manageability
The S3300 adopts a unique maintenance-free design and supports automatic conguration (auto-cong), freeing network administrators from heavy conguration workload when deploying a batch of sites.
The S3300 supports BFD and provides millisecond-level detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network reliability. Complying with IEEE 802.3ah and 802.1ag, the S3300 supports point-to-point Ethernet fault management to detect faults on user links. Ethernet OAM improves the network management and maintenance capabilities on the Ethernet and ensures a stable network. The S33HI provides hardware-based OAM and BFD functions and supports 3.3-millisecond high-precision detection.
The S3300 supports port-based and VLAN-based trafc statistics and NQA, which enables network administrators to better manage networks.
The S3300 supports the GARP Registration Protocol (GVRP). The GVRP technology implements dynamic conguration of VLANs. In a complex networking environment, GVRP can simplify VLAN conguration and reduce network communication faults caused by incorrect conguration of VLANs. This reduces the manual congurations of network administrators and ensures correct VLAN congurations.Various IPv6 Features
The S3300 hardware supports both IPv4 and IPv6, IPv6 over IPv4 tunnels (including manual tunnels, 6-to-4 tunnels, and ISATAP tunnels), and Layer-3 line-speed forwarding. Therefore, the S3300 can be deployed on IPv4 networks, IPv6 networks, and networks that run IPv4 and IPv6 simultaneously. This makes the networking exible and meets the requirements for the network transition from IPv4 to IPv6.
The S3300 supports various IPv6 routing protocols including RIPng and OSPFv3. It uses the IPv6 Neighbor.Discovery Protocol (NDP) to manage packets exchanged between neighboring nodes. The S3300 supports the .Path MTU Discovery (PMTU) mechanism. That is, it selects a proper MTU on the path from the source to the destination to optimize network resource usage and obtain the maximum throughput.Applications Serving as Access Devices in Buildings The S3300 can connect to 100-Mbit/s DSLAMs as an aggregation switch in buildings. In this case, the selective QinQ function is congured on the S3300; outer VLAN tags identify the locations of the DSLAMs or campus, and the inner VLAN tags identify users. The S3300 can also connect to home gateways directly or supply power to PSEs such as wireless APs or IP phones through PoE. This enables the S3300 to better support multi-service deployment, unied planning, ne management, and convenient maintenance of customers.
