ACI Fabric Topology
The ACI fabric topology includes the following major components:
• Application Centric Infrastructure Controller (APIC) appliance (cluster of APICs)
• Leaf switches (for switch compatibility, please see the data sheets).
• Spine switches (for switch compatibility, please see the data sheets).
For additional information, please see the Cisco APIC Installation, Upgrade, and Downgrade Guide.
To prevent sub-optimal forwarding between endpoints, connect every leaf switch in the fabric to every spine
switch in the same fabric.
Note
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.
