Switch Administrative States; Broadcast Support; In-Band Management - HP StorageWorks SN6000 User Manual

Switch administrative states

The switch administrative state determines the operational state of the switch. The switch administrative
state exists in two forms: the configured administrative state and the current administrative state.
The configured administrative state is the state that is saved in the switch configuration and is preserved
across switch resets. QuickTools always makes changes to the configured administrative state. The
configured administrative state is displayed in the Switch Properties dialog box.
The current administrative state is the state that is applied to the switch for temporary purposes and is not
retained across switch resets. The current administrative state is set using the Set Switch command. See
the HP StorageWorks SN6000 Fibre Channel Switch Command Line Interface Guide for information about
the command line interface.
The switch administrative state values are:
Online—The switch is available.
•
• Offline—The switch is unavailable.
• Diagnostics—The switch is in diagnostics mode, is unavailable, and tests can be run on all ports of the
switch.

Broadcast support

Broadcast is supported on the switch and enables 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 zones. The default setting is
Enabled.

In-band management

In-band management is the ability to manage switches across inter-switch links. QuickTools, SNMP,
management server, and the application programming interface use the in-band management capability.
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.
