H3C s3100 series Command Manual page 1067

Description
Use the arp filter source command to configure ARP packet filtering based on the gateway's IP
address on the current port. After that, ARP packets with the gateway's IP address as the sender IP
address are considered invalid and discarded.
Use the undo arp filter source command to remove the configuration.
By default, ARP packet filtering based on the gateway's IP address is disabled.
Note that:
This command should be configured on a port directly connected to hosts.
If you execute this command repeatedly, the last configured command takes effect.
Among S3100 series switches, only S3100-EI series switches support the two commands.
Examples
# Configure ARP packet filtering based on the gateway's IP address 192.168.0.1/24 on Ethernet 1/0/1.

arp filter binding
Syntax
arp filter binding ip-address mac-address
undo arp filter binding
View
Ethernet port view
Parameters
ip-address: IP address of the gateway.
mac-address: MAC address of the gateway.
Description
Use the arp filter binding command to configure ARP packet filtering based on the gateway's IP and
MAC addresses on the current port. After that, the port will discard ARP packets with the gateway's IP
address as the sender IP address but with the sender MAC address different from that of the gateway.
Use the undo arp filter binding command to remove the configuration.
By default, ARP packet filtering based on the gateway's IP and MAC addresses are disabled.
Note that:
This command should be configured on a cascaded port or upstream port of an access switch.
If you execute this command repeatedly, the last configured command takes effect.
Among S3100 series switches, only S3100-EI series switches support the two commands.
Examples
# Configure ARP packet filtering based on the gateway's IP address 192.168.100.1/24 and MAC
address 000d-88f8-528c on Ethernet 1/0/2.
