Broadcast is supported on the SANbox2 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. FSPF is used 
to setup 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 F/FL_Ports. Broadcast zoning is supported with Access Control List 
(ACL) and Virtual Private Fabric (VPF) hard zones. When a broadcast frame is 
received, these hard zones are enforced at the F/FL_Port. If the originator of the 
broadcast is in a hard zone, the frame is retransmitted on all online F/FL_Ports 
within the hard zone. If the originator of the broadcast frame is not in a hard zone, 
the frame is retransmitted on online F/FL_Ports that are not in a hard zone.

Inband management is the ability to manage switches across inter-switch links 
using SANbox Manager, SNMP, IPFC, management server, or the application 
programming interface. The switch comes from the factory with inband 
management enabled. If you disable inband management on a particular switch, 
you can no longer communicate with that switch by means other than a direct 
Ethernet or serial connection.

When a zone set is activated, SANbox2 switches and other FC-SW-2 compliant 
switches propagate the active zone set to all switches in the fabric. Some non-FC-
SW-2 compliant switches propagate not only the active zone set, but the entire 
zoning database. Disabling this parameter causes the SANbox2 switch to 
propagate the zoning database, and therefore, interoperate with non-FC-SW-2 
switches. For FC-SW-2 compliant fabrics, this parameter should be enabled.

The FC-SW-2 Compliant setting must be the same on all switches in 
the fabric, otherwise the inter-switch links will not connect.
