Techniques are described for automatic provisioning of virtual local area networks (VLANs) on server-facing ports of access switches included in a data center network. Conventionally, VLANs are pre-configured on all server-facing ports of access switches. The techniques described in this disclosure enable automatic provisioning of VLANs on server-facing ports of access switches triggered by traffic received on the ports. The techniques include a feature in a forwarding plane of an access switch that is configured to detect data packets received for an unknown VLAN on a port, and notify a control plane of the access switch of the unknown VLAN on the port. In response to the notification from the forwarding plane, the control plane may authorize and provision the VLAN on the port. The techniques described in this disclosure include hardware-assisted software provisioning of an unknown VLAN on a given port of an access switch.
