Configurable Features

		Spanning Tree Configuration
		Use this screen to activate the IEEE 802.1d Spanning Tree Protocol (STP) on
		the switch and to adjust spanning tree parameters, if necessary. In the factory
		default, STP is off. If there are any redundant paths (loops) between nodes in
		your network, you should set the Spanning Tree Enabled parameter to Yes.
		This ensures that all redundant ports (those providing backup parallel con-
		nections) are in a blocking state and not used to forward data.
		The switch automatically senses port identity and type, and automatically
		defines port cost and priority for each type. The interface allows you to adjust
		the Cost and Priority for each port, as well as the global STP parameter values
		for the switch.
		To configure the STP parameters: In most cases, the default STP param-
		eter settings are adequate. In cases where it is not, use this procedure to make
		configuration changes.
C a u t i o n		If you enable STP (step 4), it is recommended that you leave the remainder of
		the STP parameter settings at their default values until you have had an
		opportunity to evaluate STP performance in your network. Because incorrect
		STP settings can adversely affect network performance, you should avoid
		making changes without having a strong understanding of how STP operates.
		To learn the details of STP operation, refer to appendix D, “Spanning Tree
		Operation”, and examine the IEEE 802.1d standard.
