Product overview
Huawei S5720-HI series are advanced Gigabit Ethernet switches that provide rich agile features. The switches are developed based on Huawei Versatile Routing Platform (VRP), and use the fully programmable structure to implement software definition and service change on demand. With services and network convergence as the core, the switches provide the ubiquitous service function to ensure consistent user experience. The Super Virtual Fabric (SVF) function virtualizes the entire network into one device. In addition, the switches support flexible Ethernet networking, comprehensive VPN tunnel solutions, various security control methods, intelligent deployment, and simple operation and maintenance. The S5720-HI switches are the best choices for the branches of high-quality large- and middle-sized campus networks, the core layer of small-sized campus networks, and the access layer of data center networks.

Product characteristics
Enabling networks to be more agile for services
The high-speed Ethernet Network Processor (ENP) embedded in the S5720-HI is tailored for Ethernet. The chip’s flexible packet processing and traffic control capabilities can meet current and future service requirements, helping build a highly scalable network.

In addition to the capabilities of traditional switches, the S5720-HI series provide fully programmable open interfaces and support user-defined forwarding behaviors. Enterprises can use the open interfaces to develop new protocols and functions independently or jointly with equipment vendors to build campus networks meeting their own needs.

The ENP has a fully programmable architecture, on which enterprises can define their own forwarding models, forwarding behaviors, and lookup algorithms. Microcode programmability makes it possible to provide new services within six months, without the need of replacing the hardware. In contrast, traditional ASIC chips use a fixed forwarding architecture and follow a fixed forwarding process. For this reason, new services cannot be provisioned until new hardware is developed to support the services 1 to 3 years later.

Delivering abundant services more agilely
The S5720-HI series integrates the AC function with 80 Gbit/s of wireless throughput, so customers do not need to buy independent AC devices or hardware components. An S5720-HI switch can manage up to 1K APs and 16K users, coping with the fast growth of wireless services.

With the unified user management function, the S5720-HI authenticates both wired and wireless users, ensuring a consistent user experience no matter whether they are connected to the network through wired or wireless access devices. The unified user management function supports various authentication methods, including 802.1x, MAC address, and Portal authentication, and is capable of managing users based on user groups, domains, and time ranges. These functions visualize user and service management and boost the transformation from device-centered management to user-centered management.

Providing fine-grained network management more agilely
The S5720-HI series use the Packet Conservation Algorithm for Internet (iPCA) technology that changes the traditional method of using simulated traffic for fault location. iPCA technology can monitor network quality for any service flow anywhere and anytime, without extra costs. It can detect temporary service interruptions in a very short time and can identify faulty ports accurately. This cutting-edge fault detection technology turns “extensive management” to “fine-grained management.”

The S5720-HI using the Super Virtual Fabric (SVF) technology and functions as a parent switch. It can not only virtualize fixed-configuration switches into line cards of a chassis switch, but also vertically virtualize APs as ports of the chassis switch. With this virtualization technology, a physical network with the “Small-sized core/aggregation switches + Access switches + APs” structure can be virtualized into a “super switch”, offering the industry’s simplest network management solution.

With the Easy Deploy function, the S5720-HI series manage access switches in a similar way an AC manages APs. In deployment, access switches and APs can go online with zero-touch configuration. In the Easy Deploy solution, the Commander collects topology information about the connected clients and stores the clients’ startup information based on the topology. Clients can be replaced with zero-touch configuration. The Commander can deliver configurations and scripts to clients in batches and query the delivery results. In addition, the Commander can collect and display information about power consumption on the entire network.

Complete VPN Tunnels
S5720-HI series switches support the MPLS function and can work as access devices for high-quality enterprise leased lines. The S5720-HI series can connect users in different VPNs and isolate users through multi-instance routing. Users in multiple VPNs connect to a PE through the same physical uplink port on the switch, which lowers a single user’s Capital Expenditure (CAPEX) for network deployment.

Flexible Ethernet networking
In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the S5720-HI supports Huawei-developed Smart Ethernet Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a ring protection protocol specific to the Ethernet link layer, and applies to various ring network topologies, such as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable, easy to maintain, and implements fast protection switching. ERPS is defined in ITU-T G.8032. It implements millisecond-level protection switching based on traditional Ethernet MAC and bridging functions.

The S5720-HI supports Smart Link and Virtual Router Redundancy Protocol (VRRP), which implement backup of upstream links. One S5720-HI switch can connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices.

The S5720-HI series have large tables, coping with the fast growth of data volume in the big data era. With the support for 128K MAC addresses, 1M FIB entries, the S5720-HI series switch meets the requirements of educational networks and metro area networks and allows the access of a large number of terminals. The S5720-HI is the best choice in cloud computing era.

Various security control methods
The S5720-HI series support MAC address authentication and 802.1x authentication and implement dynamic delivery of VLAN, QoS, and ACL policies to users. They support port-based 802.1x, MAC address, and hybrid authentications and VLANIF interface-based portal authentication.

The S5720-HI provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. DoS attacks are targeted at switches and include SYN flood, Land, Smurf, and ICMP flood attacks. User-targeted attacks include bogus DHCP server attacks, IP/MAC address spoofing, DHCP request flood, and change of the DHCP CHADDR value.

The S5720-HI series set up and maintain the DHCP snooping binding tables, and discard the packets that do not match the table entries. Users can specify DHCP snooping trusted ports to ensure that users connect only to the authorized DHCP server.

The S5720-HI supports strict ARP learning, which prevents ARP spoofing attackers from exhausting ARP entries.

The S5720-HI supports MAC security (MACSec) that enables hop-by-hop secure data transmission. Therefore, the S5720-HI can be applied to scenarios that pose high requirements on data confidentiality, such as government and finance sectors.

Mature IPv6 features
The S5720-HI is developed based on the mature, stable VRP and supports IPv4/IPv6 dual stacks, IPv6 routing protocols (RIPng, OSPFv3, BGP4+, and IS-IS for IPv6). With these IPv6 features, the S5720-HI can be deployed on a pure IPv4 network, a pure IPv6 network, or a shared IPv4/IPv6 network, helping realize IPv4-to-IPv6 transition.

Intelligent stack (iStack)
The S5720-HI supports the iStack function that combines multiple switches into a logical switch. Member switches in a stack implement redundancy backup to improve device reliability and use inter-device link aggregation to improve link reliability. iStack provides high network scalability. You can increase ports, bandwidth, and processing capacity of a stack by simply adding member switches to the stack. iStack also simplifies device configuration and management.
