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
Insertion	determines 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.
