Integration question: Cisco ACI with f5 in unmanaged mode

From the perspective of the BIG-IP no specific configuration is needed. But you probably want to disable 'Auto Last Hop'. Check the document below at: Guidelines and Limitations for Common Pervasive Gateway

I'm not a Cisco ACI expert, but configuration of these items seem to be relevant:

ACI Access Policy for configuration of the physical ports (VPC, LACP, Speed, VLAN, Domain).

Logical Network Constructs for the network configuration (Bridge Domain, Subnets, Access Policy, EPG, Contracts.
