Huawei S5720S-28X-PWR-LI-AC Switch Product Features

  • Huawei S5720S-28X-PWR-LI-AC Switch supports 802.1x authentication, MAC-adressegodkendelse, and combined authentication on a per port basis, as well as Portal authentication on a per VLANIF interface basis, og implementerer dynamisk politikudførelse (VLAN, QoS, og ACL) til brugerne.
  • Huawei S5720S-28X-PWR-LI-AC Switch provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. DoS-angreb er rettet mod switches og inkluderer SYN flood, Jord, Smølf, og ICMP oversvømmelsesangreb. Brugermålrettede angreb inkluderer falske DHCP-serverangreb, IP/MAC adresse spoofing, DHCP-anmodningsoversvømmelse, og ændring af DHCP CHADDR-værdien.
  • Huawei S5720S-28X-PWR-LI-AC Switch collects and maintains information about access users, such as IP addresses, MAC-adresser, IP address leases, VLAN ID'er, and interface numbers in a DHCP snooping binding table. På denne måde, IP addresses and access interfaces of DHCP users can be tracked. Du kan angive DHCP-snooping betroede og upålidelige porte for at sikre, at brugere kun opretter forbindelse til den autoriserede DHCP-server.
  • Huawei S5720S-28X-PWR-LI-AC Switch supports strict ARP learning. This feature prevents ARP spoofing attackers from exhausting ARP entries so that users can connect to the Internet normally.
