Huawei S5720S-28X-PWR-LI-AC Switch Product Features
- Huawei S5720S-28X-PWR-LI-AC Switch supports 802.1x authentication, Provjera autentičnosti MAC adrese, and combined authentication on a per port basis, kao i autentikacija portala na osnovi VLANIF interfejsa, i implementira dinamičku isporuku politike (VLAN, QoS, i ACL) korisnicima.
- Huawei S5720S-28X-PWR-LI-AC Switch provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. DoS napadi su ciljani na prekidače i uključuju SYN flood, Zemljište, Štrumpf, i ICMP napadi na poplave. Napadi ciljani na korisnike uključuju lažne napade na DHCP server, Pretvaranje IP/MAC adrese, DHCP zahtjev poplava, i promjenu DHCP CHADDR vrijednosti.
- Huawei S5720S-28X-PWR-LI-AC Switch collects and maintains information about access users, such as IP addresses, MAC adrese, IP address leases, VLAN ID-ovi, and interface numbers in a DHCP snooping binding table. Na ovaj način, IP addresses and access interfaces of DHCP users can be tracked. Možete odrediti DHCP njuškanje pouzdanih i nepouzdanih portova kako biste osigurali da se korisnici povezuju samo na ovlašteni DHCP server.
- Huawei S5720S-28X-PWR-LI-AC Switch supports strict ARP learning. Ova funkcija sprječava napadače koji lažiraju ARP da iscrpe ARP unose kako bi se korisnici mogli normalno povezati na Internet.
