IP source guard configuration examples
Static IPv4 source guard binding entry configuration example
Network requirements
As shown in Figure 67, Host A and Host B are connected to ports GigabitEthernet 1/0/2 and
GigabitEthernet 1/0/1 of Device B, respectively. Host C is connected to port GigabitEthernet 1/0/2 of
Device A, and Device B is connected to port GigabitEthernet 1/0/1 of Device A. All hosts use static IP
addresses.
Configure static IPv4 source guard binding entries on Device A and Device B to meet the following
requirements:
• On port GigabitEthernet 1/0/2 of Device A, only IP packets from Host C can pass.
• On port GigabitEthernet 1/0/1 of Device A, only IP packets from Host A can pass.
• On port GigabitEthernet 1/0/2 of Device B, only IP packets from Host A can pass.
• On port GigabitEthernet 1/0/1 of Device B, only IP packets sourced from 192.168.0.2/24 can
pass. Host B can communicate with Host A by using this IP address even if it uses another NIC.
