7.1.1.3 Server Screening

The Switch supports DHCP Server Screening, a feature that denies access to rogue DHCP servers.
That is, when one or more DHCP servers are present on the network and both provide DHCP
services to different distinct groups of clients, the valid DHCP server's packets will be passed to
the client.
If you want to enable this feature, you must enable the DHCP Snooping function first. The Switch
allows users to configure up to three valid DHCP servers.
If no DHCP servers are configured, it means all DHCP server are valid.
