Turn Off Spanning Tree Portfast. Dont do this for links to switches - they should be set up as part of your spanning tree. If the current root switch goes offline or is rebooted your spanning tree needs to reconverge causing temporary connectivity failure. Filters most of outgoing BPDUs. Use the no spanning-tree vlan vlan-id command in order to disable STP on a per virtual LAN VLAN basis.

A port configured with portfast skips the listening and learning phases of the spanning-tree protocol and the port transitions directly to the forwarding state. In the UniFi Network application go to the UniFi Devices section and click on the switch in which you wish disableenable STP on an individual switch port opening the Switch Properties Panel. This is not correct howeverif you enable portfast on an interface then it will jump to the forwarding state of spanning-tree.
