ACI Fabric Topology
The ACI fabric topology includes the following major components:
• Application Centric Infrastructure Controller (APIC) appliance (cluster of APICs)
• Leaf switches (Cisco Nexus 93108TC-EX, 93108TC-FX, 93120TX, 93128TX, 93180LC-EX,
93180YC-EX, 93180YC-FX, 9332PQ, 9348GC-FXP, 9372PX, 9372PX-E, 9372TX, 9372TX-E, 9396PX,
and 9396TX switches)
• Spine switches (Cisco Nexus 9336PQ, 9364C, 9504, 9508, and 9516 switches)
As shown in the following figure, each APIC is connected to one or two leaf switches and each leaf switch
should be connected to every spine switch in the same fabric.
To prevent sub-optimal forwarding between endpoints, connect every leaf switch in the fabric to every spine
switch in the same fabric.
