Displaying And Maintaining Source Mac Address Based Arp Attack Detection; Configuration Example - HP 3600 v2 Series Configuration Manual

Displaying and maintaining source MAC address based ARP
attack detection
Task
Display attacking MAC addresses
detected by source MAC address based
ARP attack detection.

Configuration example

Network requirements
As shown in
a large number of ARP requests to the gateway, the gateway may crash and cannot process requests
from the clients. To solve this problem, configure source MAC address based ARP attack detection on the
gateway.

Configuration considerations
An attacker may forge a large number of ARP packets by using the MAC address of a valid host as the
source MAC address. To prevent such attacks, configure the gateway in the following steps:
1. Enable source MAC address based ARP attack detection and specify the filter mode.
2. Set the threshold.
3. Set the age timer for detection entries.
