Configuring a Binding Table

Configuring a Binding Table

IPSG enables the device to check IP packets against the binding table, including dynamic and static entries.

If user IP addresses are dynamically allocated by DHCP, a dynamic binding table is generated after DHCP snooping is enabled. If user IP addresses are configured statically, static binding entries are configured manually.

  • For users dynamically obtaining IP addresses through DHCP:

    <HUAWEI> system-view
    [~HUAWEI] dhcp enable //Enable DHCP globally.
    [*HUAWEI] dhcp snooping enable //Enable DHCP snooping globally.
    [*HUAWEI] interface 10ge 1/0/1
    [*HUAWEI-10GE1/0/1] dhcp snooping enable //Enable DHCP snooping on 10GE1/0/1.
    [*HUAWEI-10GE1/0/1] dhcp snooping trusted //Set 10GE1/0/1 as a trust interface.
    [*HUAWEI-10GE1/0/1] commit
  • For users using manually configured IP addresses:

    <HUAWEI> system-view
    [~HUAWEI] user-bind static ip-address mac-address 2-2-2 interface 10ge 1/0/1
    [*HUAWEI] commit
