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 box 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 Enabled option on the Switch Properties dialog box 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 and 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, click the Devices tab, and click (i) in the Details column of
the Devices data window. The Detailed Devices Display dialog box displays the specific information for
that device. See

Advanced switch properties

The Advanced Switch Properties dialog box
box is available for only the entry switch. The switch is automatically taken offline temporarily while the
timeout values are set and the switch is restored to its original state after the changes are completed. To
open the Advanced Switch Properties dialog box, open the Switch menu and select Advanced Switch
Properties. After making changes, click OK to put the new values into effect.

Timeout values

The switch timeout values determine the timeout values for all ports on the switch. The timeout values must
be the same for all switches in the fabric.
• R_A_TOV (Resource Allocation Timeout)—The maximum time a frame could be delayed and still be
delivered. The default is 10000 milliseconds.
• E_D_TOV (Error Detect Timeout)—The maximum round trip time that an operation between two N_Ports
could require. The default is 2000 milliseconds.
IMPORTANT:
absolutely necessary. The switch is temporarily placed offline to change these values.

Mismatched timeout values will disrupt the fabric. These should not be changed unless
