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, in ACL) uporabnikom.
- Huawei S5720S-28X-PWR-LI-AC Switch provides a series of mechanisms to defend against DoS attacks and user-targeted attacks. Napadi DoS so usmerjeni na stikala in vključujejo poplavo SYN, Zemljišče, Smrkec, in napadi poplav ICMP. Napadi, usmerjeni na uporabnike, vključujejo lažne napade na strežnik DHCP, Ponarejanje naslovov IP/MAC, Poplava zahtev DHCP, 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 naslovi, IP address leases, ID-ji VLAN, and interface numbers in a DHCP snooping binding table. In this way, IP addresses and access interfaces of DHCP users can be tracked. Določite lahko zaupanja vredna in nezaupanja vredna vrata za vohljanje DHCP, da zagotovite, da se uporabniki povežejo samo s pooblaščenim strežnikom DHCP.
- 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.
