ip dhcp snooping trust
no ip dhcp snooping trust
Function:
Set or delete the DHCP Snooping trust attributes of a port.
Parameters:

By default, all ports are non-trusted ports
Usage Guide:
Only when DHCP Snooping is globally enabled, can this command be set.
When a port turns into a trusted port from
a non-trusted port, the original defense action of the port will be automatically deleted; all the security history records
will be cleared (except the information in system log).

Set port ethernet1/1 as a DHCP Snooping trusted port
switch(config)#interface ethernet 1/1
switch(Config- Ethernet 1/1)#ip dhcp snooping trust
