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, all Fs (a broadcast MAC address), or a multicast MAC
address.

Usage guidelines
Static IPv4SG bindings on an interface implement the following functions:
•
Filter incoming IPv4 packets on the interface.
•
Check user validity by cooperating with the ARP attack detection feature.
You cannot configure static IPv4SG bindings on a service loopback interface.
Examples
# Configure a static IPv4SG binding on GigabitEthernet 1/0/1.
