Sign up for Kevin's live and online "CCNP R/S SWITCH (300-115) Crash Course," being conducted Dec. 17, 18, & 19, 2018 with the following link: http://bit.ly/switch-dec-18 In this episode of "The Broadcast Storm," you'll learn how to build on the DHCP Snooping configuration (covered in the last episode) to protect your network from IP spoofing (originating on a local subnet) and a gratuitous ARP man-in-the-middle attack. As promised in this episode, here's are sample configurations for both IP Source Guard and Dynamic ARP Inspection: IP SOURCE GUARD EXAMPLE: SW1# conf term SW1(config)#int range fa 0/2-24 SW1(config-if-range)#ip verify source SW1(config-if-range)#end SW1#   DYNAMIC ARP INSPECTION EXAMPLE: SW1# conf term SW1(config)#ip arp inspection vlan 1 SW1(config)#int gig 0/1 SW1(config-if)#ip arp inspection trust SW1(config-if)#int range fa 1/0/13-14 SW1(config-if-range)#ip arp inspection trust SW1(config-if-range)#end SW1#
