In which STP state does MAC address learning take place on a PortFast-enabled port?

The learning state is where MAC addresses are typically learned, but PortFast-enabled ports are configured to skip this state to provide immediate network access.

The listening state is where a port processes BPDUs to determine its role but does not learn MAC addresses or forward user traffic; PortFast bypasses this state.

The discarding state (or blocking state) prevents loops by dropping frames and does not allow MAC address learning or forwarding of user traffic.

PortFast-enabled ports are designed to connect to end devices and immediately transition to the forwarding state upon link-up, bypassing the typical listening and learning states of STP. Therefore, MAC address learning takes place once the port is already forwarding user traffic, as it assumes no loops are present.
