Chapter 5 Managing Switches 127
FDMI is comprised of the fabric-to-device interface and the application-to-fabric
interface. The fabric-to-device interface enables a device’s management information
to be registered. The application-to-fabric interface provides the framework by
which an application obtains device information from the fabric. Use the FDMI HBA
Entry Limit field on the Switch Properties dialog to configure the maximum number
of HBAs that can be registered with a switch. If the number of HBAs exceeds the
maximum number, the FDMI information for those HBAs can not be registered.
Select the FDMI option on the Switch Properties dialog to enable or disable FDMI. If
FDMI is enabled on an HBA, the HBA forwards information about itself to the
switch when the HBA logs into the switch. If FDMI is enabled on a switch, the
switch stores the HBA information in its FDMI database. Disabling FDMI on a
switch clears the FDMI database. If you disable FDMI on a switch, then re-enable it,
you must reset the ports to cause the HBAs to log in again, and thus forward HBA
information to the switch.
To view detailed FDMI information for a device, open the topology display, click the
Devices tab, and click the (i) button in the Details column of the Devices data
window. The Detailed Device Display dialog displays the specific information for
that device. Refer to “Devices Data Window” on page40 and “Displaying Detailed
Device Information” on page49 for more information.
Advanced Switch Properties
The Advanced Switch Properties dialog (FIGURE5-11) allows you to set the timeout
values. The Advanced Switch Properties dialog is available for only the entry switch.
The switch will automatically be taken offline temporarily and will be restored to its
original state after the changes are completed. To open the Advanced Switch
Properties dialog, open the Switch menu and select Advanced Switch Properties.
After making changes, click the OK button to put the new values into effect.
