The policy settings for each port appear.
LIP Ctrl Methods of change notification management.
• rxtxlip – no change notification management
• rxlip – devices attached to the port can receive change notifications
but will not propagate change notifications generated by that port to
other ports.
Note: Change notifications will be reflected back out of the port if
originated by devices attached to this port.
• txlip – 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.
• nolip – blocks change notifications from being propagated from the
port and change notifications from devices on other ports to devices
on the port.
• Managed – Note: This setting should not be used unless directed to
do so by a customer service representative.

Field Description
LIP on Insert 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 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.
LIP on Removal 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 the proper system updates are performed.
PTBI This policy ensures 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 a bad device is not allowed into the
zone.
