dhcp snooping problem!

[behdad_ccie]

hi every body

I have a problem with dhcp snooping

I have three switch ,sw1 and sw2 connect to a 3750x as distribution switch

my dhcp server is connect to sw1 and clients connect to sw2

I trusted the corresponding port and disable ip dhcp snooping information option

but when I configured dhcp snooping my client cant get ip address?

 I am grateful if someone could help me

Have you trusted the ports facing both the DHCP server AND your trunks between switches?

hi Anthony

Yes I have trusted

Enable:

debug ip dhcp snooping event

debug ip dhcp snooping packet

Get the client to try and renew/request an address though DHCP and see what the debugs say is happening.
