Dynamic IPv4 source guard binding by DHCP snooping
configuration example
Network requirements
As shown in Figure 79, the device connects to the host (client) and the DHCP server through ports
GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 respectively.
Enable DHCP and DHCP snooping on the device, so that the host (with the MAC address of 0001-0203-
0406) can obtain an IP address through the DHCP server and the IP address and the MAC address of
the host can be recorded in a DHCP snooping entry.
Enable the dynamic IPv4 source guard binding function on port GigabitEthernet 1/0/1 of the device,
allowing only packets from a client that obtains an IP address through the DHCP server to pass.
NOTE:
For detailed configuration of a DHCP server, see the
Layer 3IP Services Configuration Guide.
