Configuring the IPv4SG feature

You cannot configure the IPv4SG feature on a service loopback interface. If IPv4SG is enabled on an
interface, you cannot assign the interface to a service loopback group.

Enabling IPv4SG on an interface

When you enable IPSG on an interface, the static and dynamic IPSG are both enabled.
•
Static IPv4SG uses static bindings configured by using the ip source binding command.
•
Dynamic IPv4SG generates dynamic bindings from related source modules. IPv4SG uses the
bindings to filter incoming IPv4 packets based on the matching criteria specified in the ip verify
source command.
To implement dynamic IPv4SG, make sure the DHCP snooping or DHCP relay feature operates
correctly on the network.
To enable the IPv4SG feature on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the IPv4SG feature.

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.
Enabling IPv6SG on an interface
Command
system-view
interface interface-type
interface-number
ip verify source { ip-address |
ip-address mac-address |
mac-address }

Remarks
N/A
The following interface types are
supported:
•
Layer 2 Ethernet interface.
•
Layer 3 Ethernet interface.
•
Layer 3 Ethernet
subinterface.
•
VLAN interface.
•
Layer 3 aggregate interface.
By default, the IPv4SG feature is
disabled on an interface.
If you configure this command on
an interface multiple times, the
most recent configuration takes
effect.
