cnosPortSTPPortFastMode
Cisco Network Office Switch Port Spanning Tree Protocol Port Fast Mode
1.3.6.1.4.1.9.10.43.1.3.1.1.9
This object configures the port into the Spanning Tree port-fast mode. When enabled(1), the STP can transition the port's state directly from blocking to forwarding, and vice versa, without going through the intermediate listening and learning states. This object should only be enabled for a port that is connected to a single workstation. A port that is attached to a network segment with multiple network nodes or bridges should have this object set to disabled(2) since a temporary loop may occur when port changes state.
