Enabling a Trusted DHCP Server on an Interface (CLI Procedure)
You can configure any interface on the switch that connects to a DHCP server as a trusted interface (port). Configuring a DHCP server on a trusted interface protects against rogue DHCP servers sending leases.
You configure a trusted DHCP server on an interface, not on a VLAN. By default, all access interfaces are untrusted and all trunk interfaces are trusted.
To configure a trusted interface for a DHCP server by using the CLI (here, the interface is ge-0/0/8):

user@switch# set interface ge–0/0/8 dhcp-trusted
