Broadcast Support

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.

4.7.2.6

In-band Management

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.

4.7.2.7

Interop Mode for Zoning

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.

Note: The Interop Mode setting must be the same on all switches in the

fabric, otherwise the inter-switch links will not connect.
