Parameters
ip-address: Filters incoming packets by source IPv4 addresses.
ip-address mac-address: Filters incoming packets by source IPv4 addresses and source MAC addresses.
mac-address: Filters incoming packets by 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.
You cannot enable dynamic IPv4SG on a service loopback interface.

Parameters
ip-address: Filters incoming packets by source IPv6 addresses.
ip-address mac-address: Filters incoming packets by source IPv6 addresses and source MAC addresses.
mac-address: Filters incoming packets by source MAC addresses.
Usage guidelines
After you enable IPv6SG on an interface, this feature uses static and dynamic IPv6SG bindings to match incoming packets on the interface. Packets that match an IPv6SG binding are forwarded and packets that do not match any IPv6SG binding are discarded.
The matching criterion specified by this command applies only to dynamic IPv6SG. Static IPv6SG uses static bindings configured by using the ipv6 source binding command.

Parameters
number: Specifies the maximum number of IPv6SG bindings, in the range of 0 to 4294967294.
Usage guidelines
This command limits the total number of static and dynamic IPv6SG bindings on an interface.
If the maximum number of IPv6SG bindings is reached on an interface, no more IPv6SG bindings can be added on the interface.
If you set the maximum number of IPv6SG bindings to be smaller than the number of existing IPv6SG bindings, the configuration can be successful. The existing IPv6SG bindings are not affected. The interface does not learn IPv6SG bindings until the number of existing IPv6SG bindings is smaller than the maximum number.
The number of effective IPv6SG bindings on an interface is limited by hardware resources.
Examples
# Set the maximum number of IPv6SG bindings to 200 on FortyGigE 1/0/1.
<Sysname> system-view
[Sysname] interface fortygige 1/0/1
