ip dhcp snooping

Hi

lab testing:

3825(w/16ESW)----3750(2stack)

Microsoft 2003 dhcp is hanging off the nm-16esw on 3825. The following is configured on 3750 BUT NOT ON THE 3825:

ip dhcp snoop

ip arp inspection

port security

ip source guard

dhcp trust is on the 3750 port-channel trunk. I believe dhcp snooping should work on this scenario but it is not.

so I turned off global dhcp snoop as well as took out the vlans on "ip arp inspection" and it works. How do I get dhcp snoop to work?

Thx

You probably need to disable option 82 insertion with 'no ip dhcp snooping information option' if your DHCP server doesn't support/use option 82.

Yes, that worked. Thanks
