Broadcast zones and Admin Domains

The dotted box represents the consolidated broadcast zone, which contains all of the device that can
receive broadcast packets. the actual delivery of broadcast packets is also controlled by the Admin
Domain and zone enforcement logic. The consolidated broadcast zone is not an actual zone, but is just an
abstraction used for explaining the behavior.
In Figure 16:
• The broadcast zone for AD1 includes member devices "1,1", "3,1" and "5,1". Note that "3,1" and
"5,1" are not members of AD1. Consequently, from the AD1 broadcast zone, only "1,1" is added to the
consolidated broadcast zone.
• The broadcast zone for AD2 includes member devices "2,1", "3,1", and "4,1". Even though "2,1" is a
member of AD1, it is not a member of AD2 and so is not added to the consolidated broadcast zone.
• Device "3,1" is added t the consolidated broadcast zone because of its membership in the AD2
broadcast zone.
When a switch receives a broadcast packet it forwards the packet only to those devices that are zoned
with the sender and are also part of the consolidated broadcast zone.
You can check whether a broadcast zone has any invalid members that cannot be enforced in the current
AD context. See

Broadcast zones and FC-FC routing

If you create broadcast zones in a metaSAN consisting of multiple fabrics connected through an FC router,
the broadcast zone must include the IP device that exists in the edge or backbone fabric as well as the
proxy device in the remote fabric. See
proxy devices and the FC router.

Upgrade and downgrade considerations

If you upgrade from a Fabric OS version earlier than 5.3.0 to Fabric OS 5.3.0 or later, you must rename
any existing zones named "broadcast" before you upgrade. The firmware download fails if a pre-5.3.x
switch has a zone with the name of "broadcast" in the effective configuration.
When downgrading to a firmware version earlier than Fabric OS 5.3.0, you must remove or disable the
broadcast zone. The firmware downgrade fails if a zone with the name of "broadcast" is part of the
effective configuration.
