cisco aci use spanning tree?

Short overview about Does Cisco Aci Use Spanning Tree? and what's good to know about.

As network technologies have evolved, the need for Spanning Tree Protocol (STP) has diminished. However, STP is still needed in some cases to prevent loops. Cisco Application Centric Infrastructure (ACI) is a modern, software-defined networking (SDN) solution that uses an overlay model. This means that STP is not needed with ACI because there are no physical links between devices. The ACI fabric is made up of leaf and spine switches. The leaf switches are connected to the spine switches via ports that are configured as “uplink ports.” The leaf switches do not have STP enabled on these uplink ports.

STP is not needed with Cisco ACI because the leaf and spine switches are not physically connected. The only way to connect to the ACI fabric is through the “uplink ports” on the leaf switches. These ports are not part of the STP domain and are not used to forward traffic.
