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
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.
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.
