Huawei S5720S-28X-PWR-LI-AC Switch Product Features
- Huawei S5720S-28X-PWR-LI-AC Switch supports 802.1x authentication, MAC address authentication, and combined authentication on a per port basis, as well as Portal authentication on a per VLANIF interface basis, and implements dynamic policy delivery (VLAN, QoS, dan ACL) kepada pengguna.
- Huawei S5720S-28X-PWR-LI-AC Switch provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. Serangan DoS disasarkan pada suis dan termasuk banjir SYN, Tanah, Smurf, dan serangan banjir ICMP. Serangan yang disasarkan pengguna termasuk serangan pelayan DHCP palsu, Penipuan alamat IP/MAC, DHCP meminta banjir, and changing of the DHCP CHADDR value.
- Huawei S5720S-28X-PWR-LI-AC Switch collects and maintains information about access users, such as IP addresses, MAC addresses, IP address leases, ID VLAN, and interface numbers in a DHCP snooping binding table. Dengan cara ini, IP addresses and access interfaces of DHCP users can be tracked. Anda boleh menentukan DHCP mengintip port yang dipercayai dan tidak dipercayai untuk memastikan pengguna menyambung hanya ke pelayan DHCP yang dibenarkan.
- Huawei S5720S-28X-PWR-LI-AC Switch supports strict ARP learning. Ciri ini menghalang penyerang spoofing ARP daripada meletihkan entri ARP supaya pengguna boleh menyambung ke Internet secara normal.
