Huawei S5720S-52P-PWR-LI-AC Switch Product Features
- Huawei S5720S-52P-PWR-LI-AC Switch supports the SmartLink function. S5720S-LI は、複数のリンクを介して複数のアグリゲーション スイッチに接続されています, 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) リンク障害を迅速に検出するため.
- 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 は、イーサネット リンク層専用のリング ネットワーク プロトコルです。. ハーフリングなど様々なネットワークに最適, full ring, そしてカスケードリング. プロトコルはシンプルで信頼性が高い, メンテナンスが簡単, 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. その中で, the DoS type defense attack mainly targets the attacks of the switch itself, SYNフラッドを含む, 土地, スマーフ, and ICMP Flood; the user type defense attack involves DHCP server spoofing attacks, IP/MACスプーフィング, DHCP リクエストのフラッド, changing the DHCP CHADDR value, 等々.
- 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.
