Configuring a static IPv4SG binding

You can configure global static and interface-specific static IPv4SG bindings.

Global static bindings take effect on all interfaces.

Interface-specific static bindings take priority over global static bindings. An interface first uses the static bindings on the interface to match packets. If no match is found, the interface uses the global bindings.

The following interface types are supported:

  • Layer 2 Ethernet port.

  • Layer 2 aggregate interface.

  • Layer 3 Ethernet interface.

  • VLAN interface.

3. Configure a static IPv4SG binding.

ip source binding { ip-address ip-address | ip-address ip-address mac-address mac-address | mac-address mac-address } [ vlan vlan-id ]

By default, no static IPv4SG bindings exist on an interface.

The vlan vlan-id option is supported only in Layer 2 Ethernet interface view and Layer 2 aggregate interface view.

To configure a static IPv4SG binding for the ARP attack detection feature, make sure the following conditions are met:

  • The ip-address ip-address option, the mac-address mac-address option, and the vlan vlan-id option must be specified.

  • ARP attack detection must be enabled for the specified VLAN.

You can configure the same static IPv4SG binding on different interfaces.
