Enabling a Trusted DHCP Server (CLI Procedure)
You can configure any interface on a 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):
[edit ethernet-switching-options secure-access port]
user@switch# set interface
ge-0/0/8 dhcp-trusted Related Documentation
