Huawei S5720 - 28p - Li - AC with 24 Port Ge SFP Switch

Product features

(1)Easy operation and maintenanceThe S5720-EI supports Easy Operation, a solution that provides zero-touch deployment, replacement of faulty devices without additional configuration, USB-based deployment, batch configuration, and batch remote upgrade. The Easy Operation solution facilitates device deployment, upgrade, service provisioning, and other management and maintenance operations, and also greatly reduces O&M costs. The S5720-EI can be managed using Simple Network Management Protocol (SNMP) v1, v2c, and v3, command line interface (CLI), web-based network management system, or Secure Shell (SSH) v2.0. Additionally, it supports remote network monitoring (RMON), multiple log hosts, port traffic statistics collection, and network quality analysis, which help in network consolidation and reconstruction.The model with prepositive power sockets can be installed in the 300 mm deep cabinet, and can be maintained through the front panel. This simplifies operation and maintenance (O&M). The cabinet can be placed against the wall or back to back, meeting requirements of small cabinets and limited equipment room space.(2)Enhanced QoS capability, comprehensive security controlThe S5720-EI provides excellent quality of service (QoS) capabilities and supports queue scheduling and congestion control algorithms.it can assign traffic to a queue based on the MAC address,IP protocol type,and TCP/UDP Ports.Additionally, it adopts innovative priority queuing and multi-level scheduling mechanisms to implement fine-grained scheduling of data flows, meeting service quality requirements of different user terminals and services..The S5720-EI 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-EI sets up and maintains a DHCP snooping binding table, and discards the packets that do not match the table entries. You can specify DHCP snooping trusted and untrusted ports to ensure that users connect only to the authorized DHCP server.The S5720-EI supports strict ARP learning, which protects a network against from ARP spoofing attacks to ensure normal network access.(3)Flexible Ethernet networkingThe S5720-EI supports Smart Link and Virtual Router Redundancy Protocol (VRRP), which implement backup of uplinks. One S5720-EI switch can connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices.The S5720-EI supports LLDP as a link layer protocol used for interconnected devices to obtain the connection information of each other.  .In addition, the S5720-EI provides multiple connection fault detection mechanisms, including Ethernet OAM (IEEE 802.3ah/802.1ag /ITU Y.1731) and Bidirectional Forwarding Detection (BFD).(4)Intelligent stack (iStack)The S5720-EI 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. After a stack is set up, up to 9 physical switches can be virtualized into one logical device.The S5720-EI can join a stack through its dedicated stacking cards for lower latency, and through its service ports that are currently supported by the two 10GE ports on the 2x10G interface cards exclusively for longer distance connections.The S5720-EI provides dedicated stack cards, and the two 10GE ports on 2x10G interface cards can be used for service port stacking. (5)Mature IPv6 technologiesThe S5720-EI uses the mature, stable VRP software platform and supports IPv4/IPv6 dual stacks, IPv6 routing protocols (RIPng, OSPFv3, BGP4+, and IS-IS for IPv6), and IPv6 over IPv4 tunnels including manual, 6-to-4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnels. With these IPv6 features, the S5720-EI can be deployed on a pure IPv4 network, a pure IPv6 network, or a shared IPv4/IPv6 network, helping realize IPv4-to-IPv6 transition.
