NETGEAR Managed Switches Software Administration Manual, Release 8.0 When Dynamic ARP Inspection is enabled, the switch drops ARP packet whose sender MAC address and sender IP address do not match an entry in the DHCP snooping bindings database. However it can be overcome through Static mappings. Static mappings are useful when hosts configure static IP addresses, DHCP snooping cannot be run, or other switches in the network do not run dynamic ARP inspection. A static mapping associates an IP address to a MAC address on a VLAN. Static client IP address: 192.168.10.1 HW address: 00:11:85:EE:54:E9 Interface 1/0/1 Interface 1/0/2 GSM73xxS Interface 1/0/3 DHCP Server IP address: 192.168.10.1 DHCP Client IP address: 192.168.10.86 (obtained) HW address: 00:16:76:A7:88:CC Figure 15-37 This script in this section shows how to configure Dynamic ARP Inspection. CLI: Dynamic ARP Inspection Enable DHCP snooping globally. (Netgear Switch) (Config)# ip dhcp snooping 15-34 v1.0, October 2009 Security Management
