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.
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 13.
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 System> Services > DHCP Snooping > Global Configuration.
The DHCP Snooping Global Configuration page displays.

You can view and configure each port as a trusted or untrusted port. Any DHCP responses
received on a trusted port are forwarded. If a port is configured as untrusted, any DHCP (or
BootP) responses received on that port are discarded.
