Parameters
threshold-value: Threshold for source MAC address based ARP attack detection, in the range 10 to 100.
Description
Use the arp anti-attack source-mac threshold command to configure the threshold for source MAC
address based ARP attack detection. If the number of ARP packets sent from a MAC address within five
seconds exceeds this threshold, the switch considers this an attack.
Use the undo arp anti-attack source-mac threshold command to restore the default.
By default, the threshold for source MAC address based ARP attack detection is 50.
Examples
# Configure the threshold for source MAC address based ARP attack detection as 30.
<Sysname> system-view
