Huawei S5720S-52P-PWR-LI-AC Switch Product Features
- Huawei S5720S-52P-PWR-LI-AC Switch supports the SmartLink function. S5720S-LI, birden çok bağlantı aracılığıyla birden çok toplama anahtarına bağlanır, which implements uplink backup and greatly improves the reliability of access-side devices.
- Huawei S5720S-52P-PWR-LI-AC Switch supports complete Ethernet OAM (IEEE 802.3ah/802.1ag) bağlantı hatalarının hızlı tespiti için.
- 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, Ethernet bağlantı katmanına ayrılmış bir halka ağı protokolüdür. Yarım halka gibi çeşitli ağlar için uygundur, full ring, ve basamaklı halka. Protokolü basit ve güvenilirdir, bakımı kolay, and provides 50ms fast service switching. 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. Aralarında, DoS tipi savunma saldırısı esas olarak anahtarın saldırılarını hedef alır, SYN Flood dahil, Kara, Şirin, ve ICMP Flood; Kullanıcı tipi savunma saldırısı, DHCP sunucusu yanıltma saldırılarını içerir, IP/MAC sahtekarlığı, DHCP isteği seli, DHCP CHADDR değerini değiştirme, ve benzeri.
- 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.
