<strong>Switch</strong> administrative states<br />
The switch administrative state determines the operational state of the switch. The<br />
switch administrative state exists in two forms: the configured administrative state<br />
and the current administrative state.<br />
• Configured administrative state—the state that is saved in the switch<br />
configuration and is preserved across switch resets. QuickTools always makes<br />
changes to the configured administrative state. The configured administrative<br />
state is displayed in the <strong>Switch</strong> Properties dialog.<br />
• Current administrative state—the state that is applied to the switch for<br />
temporary purposes and is not retained across switch resets. The current<br />
administrative state is set using the Set <strong>Switch</strong> command.<br />
Table 10 describes the switch administrative state values.<br />

Description<br />
The switch is available.<br />
The switch is unavailable.<br />
The switch is in diagnostics mode, is unavailable, and tests can be<br />
run on all ports.<br />
Broadcast support<br />
Broadcast is supported on the switch and allows for TCP/IP support. Broadcast is<br />
implemented using the proposed standard specified in Multi-<strong>Switch</strong> Broadcast for<br />
FC-SW-3, T11 Presentation Number T11/02-031v0. Fabric Shortest Path First (FSPF) is<br />
used to set up a fabric spanning tree used in transmission of broadcast frames.<br />
Broadcast frames are retransmitted on all ISLs indicated in the spanning tree and all<br />
online N_Ports and NL_Ports. Broadcast zoning is supported with zones. The<br />
default setting is enabled.<br />
In-band management<br />
In-band management is the ability to manage the switches across inter-switch links<br />
using QuickTools, SNMP, management server, or the application programming<br />
interface (API). The switch comes from the factory with in-band management<br />
enabled. If you disable in-band management on a particular the switch, you can no<br />
longer communicate with that the switch by means other than a direct Ethernet or<br />
serial connection.<br />
Fabric Device Management Interface<br />
Fabric device management interface (FDMI) provides a means to gather and display<br />
device information from the fabric, and allows FDMI capable devices to register<br />
certain information with the fabric, if FDMI is enabled. QuickTools will report all<br />
FDMI information reported by the entry switch, if FDMI is enabled on the entry<br />
switch. To view FDMI data, FDMI must be enabled on the entry switch and on all<br />
other the switches in the fabric that are to report FDMI data.<br />
