Impact of DHCP snooping on other data packets on S series switch


For S series switches (except S1700 switches), the DHCP snooping function ensures that DHCP clients obtain IP addresses from authorized DHCP servers and records mappings between IP addresses and MAC addresses of DHCP clients, preventing DHCP attacks on the network. When DHCP attacks occur, a switch configured with DHCP Snooping discards attack packets while forwarding valid packets.
