Binding IP Addresses to VLANs Statically

Binding IP Addresses to VLANs Statically

IPSG based on a static binding table filters IP packets received by untrusted interfaces. Therefore, IPSG can effectively prevent malicious hosts from stealing authorized hosts' IP addresses to gain network access. IPSG based on a static binding table is applicable to a local area network (LAN) where a small number of hosts reside and the hosts use static IP addresses.

For example, add a static binding entry of source IP address 192.168.2.1 and VLAN ID 10, and enable IPSG in VLAN 10:
<HUAWEI> system-view
[HUAWEI] user-bind static ip-address 192.168.2.1 vlan 10
[HUAWEI] vlan 10
[HUAWEI-vlan10] ip source check user-bind enable
