We have recently migrated a set of our Aruba 3400 Controllers from traditional Rtr/Switch topology to Cisco ACI. The last couple months we have noticed off occurrences dealing with Packet Loss from End Users either connected to APs or RAPs. We have reloaded the 3400 Controllers a couple times and this seems to resolve the issue but only temporarily. I am not 100% convinced we have the ACI Interfaces to Aruba Interfaces configured correctly which is causing our problems.
I also want to point out I have 2 Aruba 3400s at this location configured the same with the exception of Interface IPs.

Could the way we have ACI configured be causing an issue with the trunk to the Aruba Controller?
