Change Notifications

The following settings are available.

Setting	Description

Stealth Intelligent Change	Stealth Intelligent Change Manager provides stability and control
Manager	over change notification disruptions on a port basis. Options
	include:
	• Off: No Change Protection – no Stealth Intelligent Change
	Manager control.
	• Initiator: Only Receive Changes – devices attached to the port
	can receive change notifications but will not propagate change
	notifications generated by that port to other ports.
	• Target: Only Send Changes – propagates change notifications
	generated by the port to other ports but will not allow devices
	attached to the port to receive change notifications from other
	ports.
	• Switch-Switch: Send and Receive Changes – allows change
	notifications to propagate between switches.
	• Custom-1 – Note: This setting should not be used unless
	directed to do so by a customer service representative.

Change Notification on	The switch normally operates under the condition that when a
Insertion	device is inserted onto the network, a change notification is
	generated. However, this condition is not always true when
	connecting hubs or switches together. In some instances, it is
	possible to connect two zones together without the zones realizing
	that multiple AL_PAs exist with the same values.
	When this policy is enabled, the switch always generates a change
	notification to ensure that the proper system updates are performed.
	However, when a device is removed (for example, an initiator or
	target), the removal does not generate a change notification and
	there are no system updates performed.

Change Notification on	This policy is similar to the Change Notification on Insertion policy,
Removal	except for the change notification being sent when a device is
	removed rather than inserted.
	When this policy is enabled, the switch always generates a change
	notification to ensure that the proper system updates are performed.
