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, 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 usmjereni su na preklopnike i uključuju SYN flood, Zemljište, Štrumpf, i ICMP napadi poplavama. Napadi usmjereni na korisnike uključuju lažne napade na DHCP poslužitelj, lažiranje IP/MAC adresa, Poplava DHCP zahtjeva, i mijenjanje 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 poslužitelj.
- 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.
