Huawei S5700-28X-PWR-LI-AC Product Features
- Supporting strict ARP learning, which prevents ARP spoofing attacks that exhaust ARP entries. It also provides IP source checks to prevent DoS attacks caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing.
- Reducing energy consumption without compromising system performance, ensuring good user experience. The S5700-LI adopts multiple cutting-edge energy-saving designs, including Energy Efficient Ethernet (ЕЕЕ), port energy detection, dynamic CPU frequency adjustment, and device sleeping.
- Supporting intelligent stacking (iStack). Multiple S5700s can be connected with stack cables to set up a stack, which functions as a virtual switch. A stack consists of a master switch, a backup switch, and several slave switches. The backup switch takes over services when the master switch fails, reducing service interruption time. Stacks support intelligent upgrades so that users do not need to change the software version of a switch when adding it to a stack. The iStack function allows users to connect multiple switches with stack cables to expand the system capacity. These switches can be managed using a single IP address, which greatly reduces the costs of system expansion, operation, and maintenance. Compared with traditional networking technologies, iStack has distinct advantages regarding scalability, надійність, and system architecture.
- Providing improved PoE solutions. It can use PoE power supplies with different power levels to provide -48 V DC power for powered devices (ПД), such as IP Phones, WLAN APs, and Bluetooth APs. As a power sourcing equipment (PSE), the S5700-LI PWR complies with IEEE 802.3af and 802.3at (PoE+) and can work with PDs that are incompatible with 802.3af or 802.3at. Each port provides a maximum of30 W of power, complying with IEEE 802.3at. The PoE+ function increases the maximum power available on each port and implements intelligent power management for high-power consumption applications. This facilitates the ease of PD use. PoE ports continue to work while in power-saving mode. Users can configure whether and when a PoE port supplies power
