Cisco 3750 dhcp snooping binding?

Question

Computer networks

Hello.
Is Cisco 3750 as intervlan+access and 2960 as access.
I distribute the details via dhcp with winserver.
So on 2960 I see the table
#sh ip dhcp snooping binding
And on 3750 the table is empty...
What could be the problem?
config 3750:

ip dhcp snooping vlan 2-3,10
no ip dhcp snooping information option
ip dhcp snooping

SRV-GD04#show ip dhcp snooping binding 
MacAddress          IpAddress        Lease(sec)  Type           VLAN  Interface
------------------  ---------------  ----------  -------------  ----  --------------------
Total number of bindings: 0

Answer 1

Is there ip dhcp snooping trust on the interface towards the DHCP server?
