Network requirements
As shown in
Configure static IPv4SG bindings on Switch A and Switch B to meet the following requirements:
•
FortyGigE 1/1/2 of Switch A allows only IP packets from Host C to pass.
•
FortyGigE 1/1/1 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.
•
FortyGigE 1/1/1 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 FortyGigE 1/1/2.
<SwitchA> system-view
[SwitchA] interface fortygige 1/1/2
[SwitchA-FortyGigE1/1/2] ip verify source ip-address mac-address
# On FortyGigE 1/1/2, configure a static IPv4SG binding for Host C.
