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. McDATA Web Server or Element Manager always makes changes to the
configured administrative state. The configured administrative state is displayed in the Switch Properties
dialog.
•
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 McDATA 4Gb SAN Switch for HP p-Class BladeSystem command line interface
guide for information about the command line interface.
Table 11 describes the administrative state values.

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. When a broadcast frame is received, these zones are enforced
at the N_Ports and NL_Ports. If the originator of the broadcast is in a zone, the frame is retransmitted on all
online N_Ports and NL_Ports within the zone. If the originator of the broadcast frame is not in a zone, the
frame is retransmitted on online N_Ports and NL_Ports that are not in a zone. The default setting is
disabled.

In-band management

In-band management is the ability to manage switches across ISLs using McDATA Web Server, 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 connection.
Description
The switch is available.
The switch is unavailable.
The switch is in diagnostics mode, is unavailable, and tests can then be run on
all ports of the switch. The switch must be reset after leaving the Diagnostics
state.
