126 Enterprise Fabric Suite 2007 User Guide • September 2008
TABLE 5-4 describes the administrative state values.
Broadcast Support
Broadcast is supported on the switch which 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 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
enabled.
In-band Management
In-band management is the ability to manage switches across inter-switch links
using Enterprise Fabric Suite 2007, 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.
Fabric Device Management Interface
Fabric Device Management Interface (FDMI) provides a means to gather and display
device information from the fabric, and allows FDMI capable devices to register
certain information with the fabric, if FDMI is enabled. Enterprise Fabric Suite 2007
will report 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.
