Assuming "dhcp snooping trust" has been set on the links connecting to the DHCP server, check as well IOS release notes. I stumbled over a DHCP snooping bug affecting the 6500 series when using VRF light.
Check as well logs and do a debugging on the switches:
Our Network topology consists of Access, Distribution and Core switch...
DHCP request from the client should go through these switches to get IP from DHCP server.
We tried debugging ip dhcp snooping packet and found that the packets are not coming to core switch, then we directly connected laptop to core switch but client fails to get IP address and no DHCP snooping packets are coming to Core switch...
Finally we Recreated VLAN 10 (by deleting and configuring on Core switch) and it started workingâ¦.
