# SANbox Zoning Configuration

You can set the zoning configuration parameters two ways: using SANbox Manager or with the Set Zoning Config command in the command line interface.

Default Visibility

Default visibility determines the level of communication that is permitted between devices when there is no active zone set. The default visibility can be set differently on each switch. If default visibility is enabled (All) on a switch, the switch and its devices can communicate with all devices in the fabric. When default visibility is disabled (None) on a switch, none of the ports on that switch can communicate with any other port in the fabric.
