Parameters
static: Displays static IPv4SG bindings.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. To display dynamic IPv4SG bindings for the public network, do not specify a VPN instance.
dhcp-relay: Specifies the DHCP relay agent module.
dhcp-server: Specifies the DHCP server module.
ip-address ip-address: Specifies an IPv4 address.
mac-address mac-address: Specifies a MAC address in H-H-H format.
vlan vlan-id: Specifies a VLAN ID in the range of 1 to 4094.
interface interface-type interface-number: Specifies an interface by its type and number.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays IPv4SG bindings on the active MPU.

ip source binding (interface view)
Use ip source binding to configure a static IPv4SG binding on an interface.
Use undo ip source binding to delete the static IPv4SG bindings configured on an interface.
Syntax
ip source binding ip-address ip-address mac-address mac-address

Parameters
all: Removes all static IPv4SG bindings on the interface.
ip-address ip-address: Specifies an IPv4 address for the static binding. The IPv4 address must be a class A, B, or C address, and cannot be 127.x.x.x or 0.0.0.0.
mac-address mac-address: Specifies a MAC address for the static binding. The MAC address must be in H-H-H format, and cannot be all 0s or all Fs (a broadcast MAC address).
Usage guidelines
Static IPv4SG bindings on an interface filter incoming IPv4 packets on the interface.
Examples
# Configure a static IPv4SG binding on Ten-GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/1
[Sysname-Ten-GigabitEthernet3/0/1] ip source binding ip-address 192.168.0.1 mac-address 0001-0001-0001

ip verify source
Use ip verify source to enable IPv4SG on an interface.
Use undo ip verify source to disable IPv4SG on an interface.
Syntax
ip verify source ip-address mac-address
undo ip verify source
Default
The IPv4SG feature is disabled on an interface.

Parameters
ip-address mac-address: Filters incoming packets by source IPv4 addresses and source MAC addresses.
Usage guidelines
After you enable IPv4SG on an interface, this feature uses static and dynamic IPv4SG bindings to match incoming packets on the interface. Packets that match an IPv4SG binding are forwarded and packets that do not match any IPv4SG binding are discarded.
The matching criterion specified by this command applies only to dynamic IPSG. Static IPv4SG uses static bindings configured by using the ip source binding command.
If you execute this command on an interface multiple times, the most recent configuration takes effect.
Examples
# Enable IPv4SG on Layer 3 Ethernet interface Ten-GigabitEthernet 3/0/2 and verify the source IPv4 address and MAC address for dynamic IPSG.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/2

Syntax

Parameters
all: Removes all the static IPv6SG bindings on the interface.
ip-address ipv6-address: Specifies an IPv6 address for the static binding. The IPv6 address cannot be an all-zero address, a multicast address, or a loopback address.
mac-address mac-address: Specifies a MAC address for the static binding. The MAC address must be in H-H-H format, and cannot be all 0s or all Fs (a broadcast MAC address).
Usage guidelines
Static IPv6SG bindings on an interface implement the following functions:
· Filter incoming IPv6 packets on the interface.
· Check user validity by cooperating with the ND attack detection feature.
Examples
# Configure a static IPv6SG binding on Ten-GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 3/0/1
[Sysname-Ten-GigabitEthernet3/0/1] ipv6 source binding ip-address 2001::1 mac-address 0002-0002-0002
