In default zoning mode
To configure the broadcast attribute for a default zone, follow these steps:
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# zone default-zone vsan 1
Enters the default zone configuration submode.
Step 3
switch(config-default-zone)# attribute broadcast
Sets broadcast attributes for the default zone.
Step 4
switch(config-default-zone)# no attribute broadcast
Reverts the default zone attributes to read-write (default).
About Smart Zoning
Smart zoning implements hard zoning of large zones with fewer hardware resources than was previously
required. The traditional zoning method allows each device in a zone to communicate with every other device
in the zone. The administrator is required to manage the individual zones according to the zone configuration
guidelines. Smart zoning eliminates the need to create a single initiator to single target zones. By analyzing
device-type information in the FCNS, useful combinations can be implemented at the hardware level by the
Cisco MDS NX-OS software, and the combinations that are not used are ignored. For example, initiator-target
pairs are configured, but not initiator-initiator. The device is treated as unknown if:
• The FC4 types are not registered on the device.
• During Zone Convert, the device is not logged into the fabric.
• The zone is created, however, initiator, target, or initiator and target is not specified.
The device type information of each device in a smart zone is automatically populated from the Fibre Channel
Name Server (FCNS) database as host, target, or both. This information allows more efficient utilisation of
switch hardware by identifying initiator-target pairs and configuring those only in hardware. In the event of
a special situation, such as a disk controller that needs to communicate with another disk controller, smart
zoning defaults can be overridden by the administrator to allow complete control.
Note
• Smart Zoning can be enabled at VSAN level but can also be disabled at zone level.
• Smart zoning is not supported on VSANs that have DMM, IOA, or SME applications enabled on them.
