| Description | 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.
