NOTE:
•
You can enable ARP gateway protection for up to eight gateways on a port.
•
Commands arp filter source and arp filter binding cannot be both configured on a port.
•
If ARP gateway protection works with ARP detection, MFF, ARP snooping and ARP fast-reply, ARP
gateway protection applies first.
ARP gateway protection configuration example
Network requirements
As shown in
, Client 2 launches gateway spoofing attacks to the AC. As a result, traffic that the
AC intends to send to the switch is sent to Client 2.
Configure the switch to block such attacks.
Figure 144 Network diagram
Configuration procedure
# Configure clients to connect to the AC through the interface WLAN-ESS 0.
# Configure ARP gateway protection on the AC.
[AC] interface WLAN-ESS 0
[AC-WLAN-ESS0] arp filter source 10.1.1.1
[AC-WLAN-ESS0] quit
After the configuration is complete, the AC will discard the ARP packets from Client 2 whose source IP
address is that of the gateway.
