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
Solved! Go to Solution.

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
