Port Information
The following settings are available.
Pre-Insertion Testing
The following settings are available.
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 accept-
able 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.
Setting
Description
Enable Policies/Smart
Insertion
This policy is the default operating mode for all ports and 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 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.
