Syntax
[no] ip dhcp snooping trust
Default Setting
All interfaces are untrusted
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• A trusted interface is an interface that is configured to receive only
messages from within the network. An untrusted interface is an
interface that is configured to receive messages from outside the
network or firewall.
• When DHCP snooping enabled globally using the ip dhcp snooping
command (page 23-18), and enabled on a VLAN with the ip dhcp
snooping vlan command (page 23-18), DHCP packet filtering will be
performed on any untrusted ports within the VLAN according to the
default status, or as specifically configured for an interface with the no
ip dhcp snooping trust command.
• When an untrusted port is changed to a trusted port, all the dynamic
DHCP snooping bindings associated with this port are removed.
