Enterasys Networks VH-8G manual Viewing the Current Spanning Tree Configuration

Parameter	Default	Description
FastForwarding	ENABLED	This parameter is used to enable/disabled the
		Fast Spanning Tree mode for the port. In this
		mode, ports skip the Blocked, Listening and
		Learning states and proceed straight to
		Forwarding.
		FastForwarding enables end-node workstations
		and servers to overcome time-out problems when
		the Spanning Tree Algorithm is implemented in a
		network. Therefore, FastForwarding should only
		be enabled for ports that are connected to an end-
		node device.

Viewing the Current Spanning Tree Configuration

The Spanning Tree Information screen displays a summary of the STA information for the overall bridge or for a specific port. To make any changes to the parameters for the Spanning Tree, use the Spanning Tree Configuration menu.
