Port Information

Setting	Description

Smart Setting Name	Displays the name of the Smart Setting. The Smart Setting name will
	automatically appear in the text box when selected in the scroll menu.

Smart Setting Type	The topology among switches for a port. Options include:
	• Initiator or Target Port – the default setting. Should be used when
	there are no links between switches.
	• Tree Cascade – designates the port as a tree cascade port. Use
	this setting when connecting multiple switches together in a tree
	cascade configuration. Under most conditions, this setting will
	result in acceptable performance.
	• String Cascade 1 through String Cascade 4 – designates the string
	cascade to which a port is assigned. String cascades maintain
	fairness when two or more InSpeed-based storage switches are
	serially cascaded. Switch performance may be lower when
	compared to a tree cascade configuration.

The following settings are available.

Setting	Description

Enable Policies/Smart	This policy is the default operating mode for all ports and determines
Insertion	what the switch looks for prior to allowing a port to insert into a zone.
	When the policy is enabled, an external device is sent an F7
	Initialization notification by the switch until an F7 Initialization
	notification is received from the device. Once an F7 Initialization
	notification is received, the port is inserted in the zone.
	This policy takes precedence over all other policies. When this policy
	is disabled, no additional policies are operational, and as long as a
	port transmits a signal of the correct frequency and amplitude, the
	port will be allowed in the zone.

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.
