4-3 DHCP Snooping

The section describes how to configure the DHCP Snooping parameters of the switch. The

DHCP Snooping can prevent attackers from adding their own DHCP servers to the network.

4-3.1 Configuration

This section describes how to configure DHCP Snooping setting including

：

Snooping Mode (Enabled and Disabled).

Port Mode Configuration (Trusted, Untrusted).

Web Interface

To configure a DHCP Snooping in the web interface:

1. Select “Enabled” in the Mode of

DHCP Snooping

Configuration.

2. Select “Trusted” of the specific port in the Mode of Port Mode Configuration.

3. Click Save.

Figure 4-3.1: The DHCP Snooping Configuration

Parameter description:



Snooping Mode :

Indicates the DHCP snooping mode operation. Possible modes are:

Enabled:

Enable DHCP snooping mode operation. When DHCP snooping mode operation

is enabled, the DHCP requests messages will be forwarded to trust ports and only allow

reply packets from trusted ports.
