Spanning

This menu allows you to view and configure the Spanning Tree Protocol.

▲Important: Do not change any of the SpanningTree Protocol parameters unless you are familiar with the IEEE 802.1d specification.

Table 5-17 describes each field in the Spanning menu.

ΔNote: For instructions on using this menu, see “Con- figuring Spanning Tree Parameters” on page 4-28.

For clarity, the IntraStack device is referred to as a “bridge” in this table.

	Table 5-17 Spanning Menu
Field	Description
Protocol Specifica-	Read-only field; displays the IEEE protocol specifica-
tion	tion.
Priority	Configurable field; integer (from 0 - 65535) used to
	determine the priority of the selected bridge during
	Spanning Tree configuration.
	The lower the value, the higher the bridge priority and
	the more likely it will be selected as a forwarding
	bridge (and possible, the root bridge) in a Spanning
	Tree.
Designated Root	Read-only field; displays the unique bridge ID of the
	current root bridge in the Spanning Tree. The ID is
	based on its physical address and priority.
	Designated Root is sometimes referred to as Root
	Bridge ID.
Root Cost	Read-only field; displays the calculated distance from
	the selected bridge to the root bridge, as seen from
	the selected bridge.
Root Port	Read-only field; displays the port on the selected
	bridge with the lowest cost route to the current root
	bridge.
	The port is determined during Spanning Tree configu-
	ration. If the selected bridge is the root bridge, the
	value is 0.
