Step Command

Remarks

Enable ARP gateway protection
for the specified gateway.

arp filter source

ip-address

By default, ARP gateway
protection is disabled.

Configuration example

Network requirements

As shown in

Figure 115

, Host B launches gateway spoofing attacks to Switch B. As a result, traffic that

Switch B intends to send to Switch A is sent to Host B.
Configure Switch B to block such attacks.

Figure 115

Network diagram

Configuration procedure

# Configure ARP gateway protection on Switch B.

<SwitchB> system-view

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

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

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

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

[SwitchB-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.
