Change Notifications
The following settings are available.
Port Test Before Insertion This policy ensures that a device on a port is a valid, standards-
compliant participant before allowing the device to be inserted into
a zone. The device must meet all of the FC-AL requirements along
with going through a complete change notification cycle. During the
change notification cycle, the device becomes the Initialization
Master (IM) and goes through the change notification phases. Once
the change notification cycle is complete, the device can be
inserted. This process ensures that a bad device is not allowed into
the zone.
Setting Description
Stealth Intelligent Change
Manager
Stealth Intelligent Change Manager provides stability and control
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
Insertion
The switch normally operates under the condition that when a
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
Remova
l
This policy is similar to the Change Notification on Insertion policy,
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.
