Spanning-tree PortFast causes a port to enter the spanning-tree forwarding state immediately, bypassing the listening and learning states. You can use PortFast on switch ports connected to a single workstation or server to allow those devices to connect to the network immediately, rather than waiting for the port to transition from the listening and learning states to the forwarding state.
Since you are not going to be running STP with such devices, it's pointless going through any of the other states...
Cisco advises that portFast should be used only when connecting a single end station to a switch port. If you enable PortFast on a port connected to another networking device, such as a switch, you can create network loops.
Therefore, I would be turning portfast off if that is not the case
