Table 43 Spanning Tree tab fields (continued)
Field	Description
ForwardDelay	Value (in hundredths of a second) that controls how fast a
	port changes its spanning state when moving towards the
	Forwarding state. The value determines how long the port
	stays in each of the Listening and Learning states, that
	precede the Forwarding state. The value is also used
	when a topology change has been detected and is
	underway. This ages all dynamic entries in the
	Forwarding Database.
	Note: This value is the one that this bridge is currently
	using, in contrast to dot1dStpBridge ForwardDelay which
	is the value that this bridge and all others would start
	using if/when this bridge were to become the root.]
BridgeMaxAge	Value that all bridges use for the maximum age of a
	bridge when it is acting as the root.
	Note: 802.1D-1990 specifies that the range is related to
	the value of BridgeHelloTime. The granularity of this timer
	is specified by 802.1D-1990 to be 1 second. A badValue
	error may be returned if the value set is not a whole
	number.
BridgeHelloTime	Value that the bridge uses for HelloTime when the bridge
	is acting as the root. The granularity of this timer is
	specified by 802.1D- 1990 to be one second. An agent
	may return a badValue error if a set is attempted to a
	value that is not a whole number of seconds.
TimeSinceTopologyChange	Value that all bridges use for ForwardDelay when this
	bridge is acting as the root.
	Note: 802.1D-1990 specifies that the range for this
	parameter is related to the value of
	dot1dStpBridgeMaxAge. The granularity of this timer is
	specified by 802.1D-1990 to be one second. An agent
	may return a badValue error if a set is attempted to a
	value that is not a whole number of seconds.

Transparent tab

The Transparent tab contains information about a specific unicast MAC address, which has some forwarding information for the bridge.

To view the Transparent tab:

1From the Device Manager menu bar, choose Edit > Bridge.
