What command is used to enable STP Portfast on an interface?

The command to enable STP PortFast on an interface is effectively communicated with "spanning-tree portfast." This command is used within the interface configuration mode to enable PortFast for that specific interface. When PortFast is enabled on an interface, it allows the interface to skip the listening and learning states of the Spanning Tree Protocol (STP) and transition directly to the forwarding state, which is particularly beneficial for ports that connect to end devices such as computers or printers. This reduces the time it takes for the devices to become operational on the network after being connected.

Additional commands listed may have specific use cases, but "spanning-tree portfast" directly accomplishes the task at hand without any extra qualifiers or settings. For instance, "spanning-tree portfast enable" is not a recognized command, as enabling PortFast does not require the additional "enable" keyword. Similarly, "spanning-tree portfast default" is used to enable PortFast on all appropriate interfaces globally, while "spanning-tree portfast access" is correct in some specific scenarios but is mainly used for defining PortFast on access ports. However, simply using "spanning-tree portfast" is the most direct and appropriate command to enable STP PortFast on
