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 
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.
