(2) Setting a trusted port
Points to note
Set the interface that uses the port to which a DHCP server is connected (port to
which the Layer 3 switch is connected in the figure of configuration example) as a
trusted port.
Command examples
1.
(config)# interface fastethernet 0/5
(config-if)# ip dhcp snooping trust
(config-if)# switchport mode access
(config-if)# switchport access vlan 2
(config-if)# exit
Sets port 0/5 as a trusted port. Other ports will be untrusted ports. The sequence also
sets port 0/5 as an access port and sets VLAN ID 2 as the VLAN containing port 0/5.

Configure terminal filtering for the ports on which packets are to be discarded based
on the binding database.
Command examples
1. (config)# interface fastethernet 0/1
(config-if)# ip verify source port-security
(config-if)# exit
Configures terminal filtering on port 0/1 and sets the source IP addresses and source
MAC addresses as the filtering conditions.
Notes
Terminal filters are disabled on trusted ports even when this command is set. Also
note that when DHCP snooping is enabled, terminal filtering is enabled for VLANs
that are not specified by the
