Fabric Device Management Interface
Fabric Device Management Interface (FDMI) provides a means to gather and
display device information from the fabric, and allows FDMI capable devices to
register certain information with the fabric, if FDMI is enabled. SANsurfer Switch
Manager will report any and all FDMI information reported by the entry switch, if
FDMI is enabled on the entry switch. To view FDMI data, FDMI must be enabled
on the entry switch and all other switches that are to report FDMI data.
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.
Use the FDMI Enabled radio button 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 Information (i) button in the Details column of the
Devices data window. The Detailed Devices Display dialog displays the specific
information for that device. Refer to ”Devices Data Window” on page 3-15 for
more information.

Broadcast Support
Broadcast is supported on the switch and allows for TCP/IP support. Broadcast is
implemented using the proposed standard specified in Multi-Switch Broadcast for
FC-SW-3, T11 Presentation Number T11/02-031v0. Fabric Shortest Path First
(FSPF) is used to set up a fabric spanning tree used in transmission of broadcast
frames. Broadcast frames are retransmitted on all ISLs indicated in the spanning
tree and all online N_Ports and NL_Ports. Broadcast zoning is supported with
Access Control List (ACL) hard zones. When a broadcast frame is received, these
hard zones are enforced at the N_Ports and NL_Ports. If the originator of the
broadcast is in a hard zone, the frame is retransmitted on all online N_Ports and
NL_Ports within the hard zone. If the originator of the broadcast frame is not in a
hard zone, the frame is retransmitted on online N_Ports and NL_Ports that are not
in a hard zone. The default setting is disabled.
