IP Source Guard Configuration Examples
Static Binding Entry Configuration Example
Network requirements
As shown in Figure 1-1 , Host A and Host B are connected to ports GigabitEthernet 1/0/2 and
GigabitEthernet 1/0/1 of Switch B respectively, Host C is connected to port GigabitEthernet 1/0/2 of
Switch A, and Switch B is connected to port GigabitEthernet 1/0/1 of Switch A.
Configure static binding entries on Switch A and Switch B to meet the following requirements:
z On port GigabitEthernet 1/0/2 of Switch A, only IP packets from Host C can pass.
z On port GigabitEthernet 1/0/1 of Switch A, only IP packets from Host A can pass.
z On port GigabitEthernet 1/0/2 of Switch B, only IP packets from Host A can pass.
z On port GigabitEthernet 1/0/1 of Switch B, only IP packets from Host B can pass.

Configuration procedure
1) Configure Switch A
# Configure the IP addresses of various interfaces (omitted).
# Configure port GigabitEthernet 1/0/2 of Switch A to allow only IP packets with the source MAC
address of 00-01-02-03-04-05 and the source IP address of 192.168.0.3 to pass.
