Configuration procedure 

# Configure ARP gateway protection on Device B. 

<DeviceB> system-view 

[DeviceB] interface ten-gigabitethernet 1/0/1 

[DeviceB-Ten-GigabitEthernet1/0/1] arp filter source 10.1.1.1 

[DeviceB-Ten-GigabitEthernet1/0/1] quit 

[DeviceB] interface ten-gigabitethernet 1/0/2 

[DeviceB-Ten-GigabitEthernet1/0/2] arp filter source 10.1.1.1 

Verifying the configuration 

# Verify that Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 discard the incoming ARP 
packets whose sender IP address is the IP address of the gateway. 

Configuring ARP filtering 

The ARP filtering feature can prevent gateway spoofing and user spoofing attacks. 

An interface enabled with this feature checks the sender IP and MAC addresses in a received ARP 
packet against permitted entries. If a match is found, the packet is handled correctly. If not, the 
packet is discarded. 

Configuration guidelines 

Follow these guidelines when you configure ARP filtering: 

•

 

You can configure a maximum of eight permitted entries on an interface. 

•

 

Do not configure both the 

arp filter source

 and 

arp filter binding

 commands on an interface. 

•

 

If ARP filtering works with ARP attack detection, ARP snooping, and ARP fast-reply, ARP 
filtering applies first. 

Configuration procedure 

To configure ARP filtering: 

 

Step Command 

Remarks 

1. 

Enter system view.

 

system-view 

N/A 

2. 

Enter Layer 2 Ethernet 
interface or Layer 2 aggregate 
interface view.

 

interface

 

interface-type 

interface-number

 

N/A 

3. 

Enable ARP filtering and 
configure a permitted entry.

 

arp filter binding

 

ip-address 

mac-address

 

By default, ARP filtering is 
disabled. 

 

Configuration example 

Network requirements 

As shown in 

Figure 136

, the IP and MAC addresses of Host A are 10.1.1.2 and 000f-e349-1233, 

respectively. The IP and MAC addresses of Host B are 10.1.1.3 and 000f-e349-1234, respectively. 

Configure ARP filtering on Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 of Device B to 
permit ARP packets from only Host A and Host B.
