2) Configure Switch
# Configure the IP addresses of various interfaces (omitted).
# Configure port GigabitEthernet 1/0/1 of Switch to allow only IP packets with the source MAC address
of 00-01-02-03-04-06 and the source IP address of 192.168.0.1 to pass.

Dynamic Binding Function Configuration Example
Network requirements
AC connects to Client and DHCP Server through GigabitEthernet 0/0/1 and GigabitEthernet 0/0/2
respectively. DHCP Snooping is enabled on AC.
Detailed requirements are as follows:
z
Client (with the MAC address of 00-01-02-03-04-06) obtains an IP address through the DHCP
Server.
z
On AC, create the DHCP Snooping entry of Client.
z
On port GigabitEthernet 0/0/1 of AC, enable dynamic binding function to prevent attacks from using
forged IP addresses to attack the server.
