5–Managing Switches
Configuring a Switch
5-22 59266-01 B
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. For information about
the command line interface, see the QLogic 5800V Series Stackable Fibre
Channel Switch Command Line Interface Guide.
The switch administrative state values are:
Online—switch is available.
Offline—switch is unavailable.
Diagnostics—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.
Enterprise Fabric Suite, 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.
Fabric Device Management Interface
Fabric Device Management Interface (FDMI) provides a means to gather and
display device information from the fabric and enables FDMI-capable devices to
register certain information with the fabric, when FDMI is Enabled. Enterprise
Fabric Suite reports 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 on all other switches in the fabric which are to report FDMI
data.
