How to configure an interface to allow only access from certain IP addresses

To configure an interface to allow access from certain IP addresses, configure an ACL to match the IP addresses, reference the ACL in a traffic policy, and apply the traffic policy to the interface. For example, to allow only the user with IP address to access GE0/0/1, run the following commands:

[HUAWEI] acl number 3030
[HUAWEI-acl-adv-3030] rule permit ip source 0
[HUAWEI-acl-adv-3030] quit
[HUAWEI] acl number 3031
[HUAWEI-acl-adv-3031] rule permit ip
[HUAWEI] traffic classifier test1
[HUAWEI-classifier-test1] if-match acl 3030
[HUAWEI] traffic classifier test2
[HUAWEI-classifier-test2] if-match acl 3031
[HUAWEI] traffic behavior test1
[HUAWEI-behavior-test1] permit
[HUAWEI] traffic behavior test2
[HUAWEI-behavior-test2] deny
[HUAWEI] traffic policy test
[HUAWEI-trafficpolicy-test] classifier test1 behavior test1
[HUAWEI-trafficpolicy-test] classifier test2 behavior test2
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] traffic-policy test inbound
