Concept of Fiber Optic Switches Zoneset
In order to bring the created zones together for ease of deployment and management a zoneset is employed (also called zoning config). A zoneset is merely a logical container for the individual zones, that are designed to work at the same time. A zoneset can contain WWN zones, port zones, or a combination of both (hybrid zones). The zoneset must be activated within the fabric (i.e. distributed through all the switches and then simultaneously enforced). Switches may contain more than one zon.
