Insight Managed 8-Port Gigabit Ethernet Smart Cloud Switch with 2 SFP Fiber Ports
DHCP snooping acts like a firewall between untrusted hosts and DHCP servers. It also
provides way to differentiate between untrusted interfaces connected to the end user and
trusted interfaces connected to the DHCP server or another switch.
Enable the Global DHCP Snooping Settings
You can view and configure the global settings for DHCP snooping.
 To enable the global DHCP snooping settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Access the Switch on page 11.
The login window opens.
4. Enter the switch’s password in the password field.
The default password is password. If you added the switch to a network on the Insight
app before and you did not yet change the password through the local browser interface,
enter your Insight network password.
The System Information page displays.
5. Select Systemï€ > Services > DHCP Snooping > Global Configuration.
The DHCP Snooping Global Configuration page displays.
6. Select the DHCP Snooping Mode Enable radio button.
7. To enable the verification of the sender’s MAC address for DHCP snooping, select the MAC
Address Validation Enable radio button.
When MAC address validation is enabled, the device checks packets that are received on
an untrusted interface to verify that the MAC address and the DHCP client hardware
address match. If the addresses do not match, the device drops the packet.
8. Click the Apply button.
Your settings are saved.
Enable DHCP for All Interfaces in a VLAN
 To enable DHCP snooping for all interfaces that are members of a VLAN:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
