26-2
Function:
Set the threshold of received messages of the port-based ARP scanning prevention. If the rate of received ARP
messages exceeds the threshold, the port will be closed. The unit is packet/second. The “no anti-arpscan port-based
threshold” command will reset the default value, 10 packets/second.
Parameters:
rate threshold, ranging from 2 to 200.
Default Settings:
10 packets /second.
Command Mode:
Global Configuration Mode.
User Guide:
the threshold of port-based ARP scanning prevention should be larger than the threshold of IP-based ARP scanning
prevention, or, the IP-based ARP scanning prevention will fail.
Example:
Set the threshold of port-based ARP scanning prevention as 10 packets /second.
Switch (config) #anti-arpscan port-based threshold 10
26.3 anti-arpscan ip-based threshold
Command:
anti-arpscan ip-based threshold
<threshold-value>
no anti-arpscan ip-based threshold
Function:
Set the threshold of received messages of the IP-based ARP scanning prevention. If the rate of received ARP
messages exceeds the threshold, the IP messages from this IP will be blocked. The unit is packet/second. The “no
anti-arpscan ip-
based threshold” command will reset the default value, 3 packets/second.
Parameters:
rate threshold, ranging from 1 to 200.
