Which Cisco ACI setting corresponds to the VMware MAC pinning?

Route based on MAC hash is a load balancing method that hashes the source or destination MAC address, which is different from MAC pinning's consistent path mechanism.

Route based on IP hash is a load balancing method that hashes source or destination IP addresses, which is not equivalent to MAC pinning.

Route based on physical NIC load is a dynamic load balancing method that distributes traffic based on NIC utilization, which is not the static mapping provided by MAC pinning.

VMware MAC pinning, when used in conjunction with Cisco ACI, ensures that a virtual machine's traffic consistently egresses the same physical NIC and therefore the same ACI leaf port, which in ACI terms corresponds to routing based on the originating virtual port. This behavior ensures traffic from a specific VM always uses the same path, aligning with MAC pinning's purpose.
