Solved: Re: C1000 not getting IPs from DHCP server when IP DHCP snooping is on

I am having an issue where my AP is not getting an IP from the DHCP server when IP DHCP snooping is on. We are using a DHCP server on a different network. The AP is on VLAN 100 but we are NOT snooping VLAN 100, just other VLANs. We have IP DHCP snooping trust on trunk links on both sides. no ip dhcp snooping information option on. Snooping limit rate on the port but its not triggering anything. This issue seems to happen only on the C1000. The config is mirrored off of a known working 3650, but doesn't work on the C1000. AP works on 3650 and 9300. Anything will help! Thank you.

Madam, it all depends , in Riemann geometries the earth can be perfectly flat! The nun thanked him , he tripped and fell forward : the poor animal had forgotten that he might be living in a Riemann geometry too!
