Huawei S5720S-52P-PWR-LI-AC Switch Product Features
- Huawei S5720S-52P-PWR-LI-AC Switch supports the SmartLink function. The S5720S-LI is connected to multiple aggregation switches through multiple 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 (IEEE 802.3ah/802.1ag) for fast detection of link failures.
- 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 is a ring network protocol dedicated to the Ethernet link layer. It is suitable for various networking such as half ring, full ring, and cascade ring. Its protocol is simple and reliable, հեշտ է պահպանել, 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. Նրանց թվում, the DoS type defense attack mainly targets the attacks of the switch itself, including SYN Flood, Հողատարածք, Smurf, and ICMP Flood; the user type defense attack involves DHCP server spoofing attacks, IP/MAC spoofing, DHCP-ի հարցում ջրհեղեղ, changing the DHCP CHADDR value, եւ այլն.
- 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.
