Default zoning access modes

Zone configurations
A zone configuration is a group of one or more zones. A zone can be included in more than one
zone configuration. When a zone configuration is enabled, all zones that are members of that
configuration are in effect.
Several zone configurations can reside on a switch at once, and you can quickly alternate between
them. For example, you might want to have one configuration enabled during the business hours
and another enabled overnight. However, only one zone configuration can be enabled at a time.
The different types of zone configurations are:
• Defined configuration
The complete set of all zone objects defined in the fabric.
• Enabled configuration
A single zone configuration that is currently in effect. The enabled configuration is built when you
enable a specified zone configuration.
Default zoning access modes
The default zoning mode controls device access if zoning is not implemented or if there is no
enabled zone configuration. Default zoning has two access modes:
• All Access—All devices within the fabric can communicate with all other devices.
• No Access—Devices in the fabric cannot access any other device in the fabric.
The default setting is All Access. Changing the default access mode requires committing the
ongoing transaction for the change to take effect.
The default zoning mode takes effect when you disable the effective zone configuration. If your
default zone has a large number of devices, to prevent RSCN storms from overloading those
devices, you should set the default zoning mode to No Access before attempting to disable the
zone configuration. If your default zone includes more than 300 devices, the zoning software
prevents you from disabling the zoning configuration if the default zoning mode is All Access.
Setting the default zoning mode
This procedure sets the default zoning mode and saves the modified zoning configuration to
nonvolatile memory.
1. Issue the RPC to configure the node in the
urn:brocade.com:mgmt:brocade-zone namespace.
2. Under the node, include the node element.
3. Under the node, include the following leaf elements.
a. In the element, specify either “allaccess” or “noaccess”.
b. In the element, specify “cfg-save” to save the modified configuration to
nonvolatile memory.
The following example sets the default zoning mode to No Access in the enabled configuration, and
saves the change to nonvolatile memory.
