Huawei S5700 Ethernet Switches provide powerful support for services
The S5700 supports IGMP v1/v2/v3 snooping, IGMP filter, IGMP fast leave, and IGMP proxy. The S5700 supports wire-speed replication of multicast packets between VLANs, multicast load balancing among member interfaces of a trunk, and controllable multicast, meeting requirements for IPTV and other multicast services.
The Multi-VPN-Instance CE (MCE) function isolates users in different VLANs, ensuring data security and reducing costs.
S5700HI switches are cost-effective, case-shaped MPLS switches. They support MPLS, VPLS, and VLL functions and can be used as high-quality access devices to provide leased line services for enterprises.
Comprehensive reliability mechanisms
Besides STP, RSTP, and MSTP, the S5700 supports enhanced Ethernet reliability technologies, such as Smart Link and Rapid Ring Protection Protocol (RRPP), which implement millisecond-level protection switchover and ensure network reliability. The S5700 also provides Smart Link multi-instance and RRPP multi-instance to implement load balancing among links, optimizing bandwidth usage.
Enhanced Trunk (E-Trunk) enables a Customer Edge (CE) to be dual-homed to two Provider Edges (PEs) (S5700s). E-Trunk greatly enhances link reliability and implements link aggregation between devices, which improves access device reliability.
The S5700 supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer on an Ethernet network. SEP can be used on open ring networks and can be deployed on upper-layer aggregation devices to provide fast switchover (within 50 ms), ensuring continuous transmission of services. SEP features simplicity, high reliability, fast switchover, easy maintenance, and flexible topology, facilitating network planning and management.
The S5700 supports Ethernet Ring Protection Switching (ERPS), also referred to as G.8032. As the latest ring network protocol, ERPS was developed based on traditional Ethernet MAC and bridging functions and uses a mature Ethernet OAM function and a Ring Automatic Protection Switching (R-APS) mechanism to implement millisecond-level protection switching. ERPS supports various services and allows flexible networking, helping customers build a network with lower OPEX and CAPEX.
The S5700 supports redundant power supplies and simultaneous use of AC and DC power. Users can choose either one or two power supplies to ensure device reliability.
The S5700EI supports VRRP and can set up VRRP groups with other Layer 3 switches. VRRP provides redundant routes to ensure stable and reliable communications. Multiple equal-cost routes to an uplink device can be configured on the S5700 to provide route redundancy. When an active route is unreachable, traffic is switched to a backup route.
BFD improves network reliability by providing millisecond-level fault detection for protocols such as OSPF, IS-IS, VRRP, and PIM. Complying with IEEE 802.3ah and 802.1ag, the S5700 supports point-to-point Ethernet fault management and can detect faults within the last mile of an Ethernet link to users.
The S5700HI provides 3.3 millisecond hardware-based Ethernet OAM function and Y.1731, which can quickly detect and locate faults. Ethernet OAM and switchover technologies can provide millisecond-level protective switchovers for networks.
Well-designed QoS policies and security features
The S5700 implements complex traffic classification based on packet information, such as 5-tuple, IP preference, ToS, DSCP, IP protocol type, ICMP type, TCP source port, VLAN ID, Ethernet protocol type, and CoS. ACLs can be applied to inbound or outbound directions on an interface. The S5700 supports a flow-based, two-rate, three-color CAR. Each port supports eight priority queues and multiple queue scheduling algorithms, such as WRR, DRR, SP, WRR + SP, and DRR + SP. All of these ensure the quality of voice, video, and data services.
The S5700 provides multiple security measures to defend against Denial of Service (DoS) attacks, as well as attacks against networks or users. DoS attack types 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 spoofing attacks, and DHCP request flood attacks. DoS attacks that change the CHADDR field in DHCP packets are also attacks against users.
The S5700 supports DHCP snooping, which discards invalid packets that do not match any binding entries, such as ARP spoofing packets and IP spoofing packets. This prevents ‘man-in-the-middle’ attacks to campus networks that hackers initiate by using ARP packets. The interface connected to a DHCP server can be configured as a trusted interface to protect the system against bogus DHCP server attacks.
The S5700 supports strict ARP learning, which prevents ARP spoofing attacks that exhaust ARP entries. It also provides IP source checks to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing.
The S5700 supports centralized MAC address authentication, 802.1x authentication, and NAC. It authenticates users based on statically or dynamically bound user information, such as the user name, IP address, MAC address, VLAN ID, access interface, and flag indicating whether antivirus software is installed. VLANs, QoS policies, and ACLs can be dynamically applied to users.
The S5700 can limit the number of MAC addresses learned on an interface to prevent attackers from exhausting MAC address entries by using bogus source MAC addresses. This function minimizes the packet flooding that occurs when users’ MAC addresses cannot be found in the MAC address table.
Fine-grained traffic management
The NetStream module supports V5, V8, and V9 packet formats and provides various traffic analysis functions, such as real-time traffic sampling, dynamic report generation, traffic attribute analysis, and traffic exception reporting. Administrators can monitor network status in real time, and the module provides applications and analysis functions, including potential fault detection, effective fault rectification, fast problem handling, and security monitoring to help customers optimize network structure and adjust resource deployment.
The Sampled Flow (sFlow) function uses a sampling mechanism to obtain statistics about traffic forwarded on a network and sends the statistics in real time to the Collector, which analyzes traffic statistics to help customers manage network traffic efficiently. The S5700-EI integrates the sFlow Agent module and uses hardware for traffic monitoring. Unlike traffic monitoring through port mirroring, sFlow does not degrade network performance.
Maintenance-free design for easy manageability
The S5700 supports automatic configuration, plug-and-play features, deployment using a USB flash drive, and batch remote upgrades. These capabilities simplify device management and maintenance and reduce maintenance costs. The S5700 supports SNMP v1/v2/v3 and provides flexible methods for managing devices. Users can manage the S5700 using the Command Line Interface (CLI), Web Network Management System (NMS), Telnet, and HGMP. The Network Quality Analyzer (NQA) function assists users with network planning and upgrades. In addition, the S5700 supports NTP, SSH v2, HWTACACS, RMON, log hosts, and port-based traffic statistics.
GARP VLAN Registration Protocol (GVRP) dynamically distributes, registers, and propagates VLAN attributes to reduce manual configuration and ensure correct VLAN configuration. In a complex network topology, GVRP simplifies VLAN configuration and reduces network communication faults caused by incorrect VLAN configuration.
The S5700 PWR provides improved Power over Ethernet (PoE) solutions. It can use PoE power supplies with different power levels to provide -48V DC power for Powered Devices (PDs), such as IP phones, WLAN APs, and Bluetooth APs. As Power Sourcing Equipment (PSE), the S5700 PWR complies with IEEE 802.3af and 802.3at (PoE+) and can work with PDs that are incompatible with 802.3af or 802.3at. Each port provides a maximum of 30W of power, complying with IEEE 802.3at. The PoE+ function increases the maximum power available on each port and implements intelligent power management for high-power consumption applications, facilitating the ease of PD use. PoE ports continue to work while in power-saving mode. Users can configure whether and when a PoE port supplies power.
Highly scalable Gigabit Ethernet switching with Huawei iStack Technology
The S5700 supports intelligent stacking (iStack). Multiple S5700s can be connected with stack cables to set up a stack, which functions as a virtual switch. A stack consists of a master switch, a backup switch, and several slave switches. The backup switch takes over services when the master switch fails, reducing service interruption time. Stacks support intelligent upgrades so that users do not need to change a switch’s software version when adding it to a stack. The iStack function allows users to connect multiple switches with stack cables to expand the system capacity. These switches can be managed using a single IP address, greatly reducing the costs of system expansion, operation, and maintenance. Compared with traditional networking technologies, iStack has distinct advantages regarding scalability, reliability, and system architecture.
Various IPv6 features
The S5700 supports IPv4/IPv6 dual stack and can migrate from an IPv4 network to an IPv6 network. S5700 hardware supports IPv4/IPv6 dual stack, IPv6 over IPv4 tunnels (including manual tunnels, 6to4 tunnels, and ISATAP tunnels), and Layer 3 line-speed forwarding. The S5700 can be deployed on IPv4 networks, IPv6 networks, or on networks that run both IPv4 and IPv6. This makes networking flexible and enables easy migration from IPv4 to IPv6.
Innovative energy-efficient design
The S5700-LI offers customers extensive energy-saving options through standard mode, basic mode, and advanced mode, which accommodates most needs. By matching port link down/up, optical-module in-place/out-of-place, port shut down/undo shutdown, idle period, and busy period, users can increase dynamic energy savings and reduce power consumption.
Models S5700-LI, S5710-EI, and S5700-HI use Energy Efficient Ethernet (EEE), port energy detection, CPU variable-frequency and device hibernation technologies, greatly reducing energy consumption and noise without compromising performance and stability.
