IP source guard configuration examples
Static IPv4 source guard binding entry configuration example
Network requirements
As shown in Figure 120, Host A and Host B are connected to ports Ethernet 1/0/2 and Ethernet 1/0/1
of Device B respectively, Host C is connected to port Ethernet 1/0/2 of Device A, and Device B is
connected to port Ethernet 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 Ethernet 1/0/2 of Device A, only IP packets from Host C can pass.
• On port Ethernet 1/0/1 of Device A, only IP packets from Host A can pass.
• On port Ethernet 1/0/2 of Device B, only IP packets from Host A can pass.
• On port Ethernet 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 network adapter.
