IPSG configuration examples
Static IPv4SG configuration example
Network requirements
As shown in Figure 106, all hosts use static IP addresses.
Configure static IPv4SG bindings on Switch A and Switch B to meet the following requirements:
• Ten-GigabitEthernet 1/0/2 of Switch A allows only IP packets from Host C to pass.
• Ten-GigabitEthernet 1/0/1 of Switch A allows only IP packets from Host A to pass.
• All interfaces of Switch B allow IP packets from Host A to pass.
• Ten-GigabitEthernet 1/0/1 of Switch B allows IP packets from Host B to pass.

Configuration procedure
1. Configure Switch A:
# Configure IP addresses for the interfaces. (Details not shown.)
# Enable IPv4SG on Ten-GigabitEthernet 1/0/2.
<SwitchA> system-view
[SwitchA] interface ten-gigabitethernet 1/0/2
[SwitchA-Ten-GigabitEthernet1/0/2] ip verify source ip-address mac-address
# On Ten-GigabitEthernet 1/0/2, configure a static IPv4SG binding for Host C.
[SwitchA-Ten-GigabitEthernet1/0/2] ip source binding ip-address 192.168.0.3
mac-address 0001-0203-0405
[SwitchA-Ten-GigabitEthernet1/0/2] quit
