USER’S GUIDE |
Port Information
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 |
| serially cascaded. Switch performance may be lower when |
| compared to a tree cascade configuration. |

Pre-Insertion Testing
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 |
| 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. |
