Configuring Network Security DHCP Snooping Configuration VLAN Configuration Display 3) Click Apply. Displays the VLANs that have been enabled with DHCP Snooping. 3.1.2 Configuring DHCP Snooping on Ports Choose the menu Network Security > DHCP Snooping > Port Config to load the following page. Figure 3-2 Port Config Follow these steps to configure DHCP Snooping on the specified port: 1) Select one or more ports and configure the parameters. Trusted Port Select Enable to set the port that is connected to the DHCP server as a trusted port. Select Disable to set the other ports as untrusted ports. MAC Verify Enable or disable the MAC Verify feature. There are two fields in the DHCP packet that contain the MAC address of the host. The MAC Verify feature compares the two fields of a DHCP packet and discards the packet if the two fields are different. This prevents the IP address resource on the DHCP server from being exhausted by forged MAC addresses. Configuration Guide 405
