DHCP 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.
