Auto Refresh: 

Enable/Disable the Auto Refresh feature. 

Refresh Interval: 

Specify the refresh interval to display the ARP Statistics. 

 

Illegal ARP  Packet 

Port: 

Displays the port number.   

Trusted Port: 

Indicates the port is an ARP Trusted Port or not.   

Illegal ARP  Packet: 

Displays the number of the received illegal ARP  packets. 

13.4 DoS Defend 

DoS (Denial of Service) Attack is to occupy the network bandwidth maliciously by the network 
attackers or the evil programs sending a lot of service requests to the Host, which incurs an 

abnormal service or even breakdown of the network.   
With DoS Defend function enabled, the switch can analyze the specific fields of the IP packets and 

distinguish the malicious DoS attack packets. Upon detecting the packets, the switch will discard
