Configuring Network Security Network Security 1 Network Security 1.1 Overview Network Security provides multiple protection measures for the network. Users can configure the security functions according to their needs. 1.2 Supported Features The switch supports multiple network security features, for example, IP-MAC Binding, DHCP Snooping, ARP Inspection and so on. IP-MAC Binding IP-MAC Binding is used to bind the IP address, MAC address, VLAN ID and the connected port number of the specified host. Basing on the IP-MAC binding table, the switch can prevent the ARP cheating attacks with the ARP Detection feature and filter the packets that don't match the binding entries with the IP Source Guard feature. The binding entries can be manually configured, or learned by ARP scanning or DHCP snooping. IPv6-MAC Binding IPv6-MAC Binding is used to bind the IPv6 address, MAC address, VLAN ID and the connected port number of the specified host. Basing on the IPv6-MAC binding table, the switch can prevent the ND attacks with the ND Detection feature and filter the IPv6 packets that don't match the binding entries with the IP Source Guard feature. The binding entries can be manually configured, or learned by ND Snooping or DHCPv6 snooping. DHCP Snooping DHCP Snooping supports the basic DHCP security feature and the Option 82 feature. Basic DHCP Security During the working process of DHCP, generally there is no authentication mechanism between the DHCP server and the clients. If there are several DHCP servers on the network, security problems and network interference will happen. DHCP Snooping resolves this problem. Configuration Guide 718
