Chapter 11  Network Security 
Network Security module is to provide the multiple protection measures for the network security, 
including four submenus: IP-MAC Binding, ARP Inspection, DoS Defend and 802.1X. Please 
configure the functions appropriate to your need. 
11.1 IP-MAC Binding 
The IP-MAC Binding function allows you to bind the IP address, MAC address, VLAN ID and the 
connected Port number of the Host together. Based on the IP-MAC binding table and ARP 
Inspection functions, you can control the network access and only allow the Hosts matching the 
bound entries to access the network. 
The following three IP-MAC Binding methods are supported by the switch. 
1)  Manually: You can manually bind the IP address, MAC address, VLAN ID and the Port 
number together in the condition that you have got the related information of the Hosts in the 
LAN.  
2)  Scanning: You can quickly get the information of the IP address, MAC address, VLAN ID 
and the connected port number of the Hosts in the LAN via the ARP Scanning function, 
and bind them conveniently. You are only requested to enter the range of the IP address 
on the ARP Scanning page for the scanning. 
3)  DHCP Snooping: You can use DHCP Snooping functions to monitor the process of the 
Host obtaining the IP address from DHCP server, and record the IP address, MAC address, 
VLAN and the connected Port number of the Host for automatic binding. 
These three methods are also considered as the sources of the IP-MAC Binding entries. The 
entries from various sources should be different from one another to avoid collision. Among the 
entries in collision, only the entry from the source with the highest priority will take effect. These 
three sources (Manual, Scanning and Snooping) are in descending order of priority. 
The  IP-MAC Binding function is implemented on the Binding Table,  Manual Binding,  ARP 
Scanning
 and DHCP Snooping pages.
