4 – Managing Switches Configuring a Switch

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 3-15for 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.

4.7.2.6

In-band Management

In-band management is the ability to manage switches across inter-switch links using SANsurfer Switch Manager, SNMP, management server, or the application programming interface. The switch comes from the factory with in-band management enabled. If you disable in-band management on a particular switch, you can no longer communicate with that switch by means other than a direct Ethernet or serial connection.
