Huawei S5720S-52P-PWR-LI-AC Switch Product Features
- Huawei S5720S-52P-PWR-LI-AC Switch supports the SmartLink function. O S5720S-LI está conectado a vários switches de agregação por meio de vários links, which implements uplink backup and greatly improves the reliability of access-side devices.
- Huawei S5720S-52P-PWR-LI-AC Switch supports complete Ethernet OAM (IEEE802.3ah/802.1ag) para detecção rápida de falhas de link.
- Huawei S5720S-52P-PWR-LI-AC Switch supports the traditional STP/RSTP/MSTP spanning tree protocol, and Huawei’s self-innovated SEP intelligent Ethernet protection technology and the industry’s latest Ethernet ring network standard ERPS. SEP é um protocolo de rede em anel dedicado à camada de link Ethernet. É adequado para várias redes, como meio anel, full ring, e anel em cascata. Seu protocolo é simples e confiável, de fácil manutenção, e fornece troca rápida de serviço de 50 ms. ERPS is the G.8032 standard released by ITU-T. This standard is based on traditional Ethernet MAC and bridge functions, and implements millisecond-level fast protection switching for Ethernet ring networks.
- Huawei S5720S-52P-PWR-LI-AC Switch supports complete DoS attack defense and user attack defense. Entre eles, the DoS type defense attack mainly targets the attacks of the switch itself, incluindo inundação SYN, Terra, Smurf, e inundação ICMP; the user type defense attack involves DHCP server spoofing attacks, Falsificação de IP/MAC, Inundação de solicitações DHCP, changing the DHCP CHADDR value, e assim por diante.
- Huawei S5720S-52P-PWR-LI-AC Switch supports the establishment and maintenance of the DHCP Snooping binding table to directly discard the illegal packets that do not conform to the binding table entries. Using the trusted port feature of DHCP Snooping, the S5720S-LI can also ensure the legitimacy of the DHCP server.
