Bay Technical Associates manual Using the BayStack 350 10/100 Autosense Switch, 3-44

Using the BayStack 350 10/100 Autosense Switch

Table 3-14. Spanning Tree Switch Settings parameters (continued)

Parameter	Description
Forward Delay	Indicates the Forward Delay parameter value that the root bridge is currently using. This
	value specifies the amount of time that the bridge ports remain in the Listening and
	Learning states before entering the Forwarding state.
	Note that the root bridge’s Forward Delay parameter value becomes the (actual) Forward
	Delay parameter value for all bridges participating in the spanning tree network. See also
	Bridge Forward Delay.
	Default Value	15
	Range	4 to 30 seconds
Bridge Hello	Indicates the Hello interval (the amount of time between transmissions of Configuration
Time	Bridge PDUs) specified by management for this bridge. This parameter takes effect only
	when this bridge becomes the root bridge.
	Note that, although you can set the Hello interval for a bridge using bridge management
	software, once the spanning tree computation process is complete, all bridges
	participating in the spanning tree network use the root bridge’s Hello Interval parameter
	value. If any bridge becomes the root bridge, its Hello Interval parameter value becomes
	the (actual) Hello Interval parameter value for all bridges participating in the spanning
	tree network. See also Hello Time.
	Default Value	2
	Range	1 to 10 seconds
Bridge	Specifies the maximum age (in seconds) that a Hello message can attain before it is
Maximum Age	discarded. This parameter, set for this bridge by management, takes effect only when
Time	this bridge becomes the root bridge.
	Note that, if this bridge becomes the root bridge, its Maximum Age Time parameter value
	becomes the (actual) Maximum Age Time parameter value for all bridges participating in
	the spanning tree network. See also Maximum Age Time.
	Default Value	20
	Range	6 to 40 seconds
Bridge Forward	Indicates the Forward Delay parameter value specified by management for this bridge.
Delay	This parameter takes effect only when this bridge becomes the root bridge.
	The Forward Delay parameter value specifies the amount of time that the bridge ports
	remain in the Listening and Learning states before entering the Forwarding state.
	Note that all bridges participating in the spanning tree network use the root bridge’s
	Forward Delay parameter value. See also Forward Delay.
	Default Value	15
	Range	4 to 30 seconds
