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. Broadcast zoning is supported with 
Access Control List (ACL) 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 disabled.

In-band management is the ability to manage switches across inter-switch links 
using SANsurfer Switch Manager, 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.

When a zone set is activated, 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 
the Interop Mode parameter causes the switch to propagate the zoning database, 
and therefore, interoperate with non-FC-SW-2 switches. For FC-SW-2 compliant 
fabrics, the Interop Mode parameter should be enabled. 

The Interop Mode setting must be the same on all switches in the 
fabric, otherwise the inter-switch links will not connect.
