Dynamic IPv4 source guard using DHCP snooping

Network requirements
As shown in
GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2, respectively. The host obtains an IP address from
the DHCP server.
Enable DHCP snooping on the device to record the DHCP snooping entry of the host. Enable the IPv4
source guard function on the device's port GigabitEthernet 1/0/1 to filter packets based on the DHCP
snooping entry, allowing only packets from clients that obtain IP addresses through the DHCP server to
pass.
For information about DHCP server configuration, see Layer 3—IP Services Configuration Guide.
