Device Access
Consider device access needs within the fabric. Access is controlled by the use of
zones and zone sets. Some zoning strategies include the following:
zones and zone sets. Some zoning strategies include the following:
Separate devices by operating system
Separate devices that have no need to communicate with other devices in
the fabric or have classified data.
the fabric or have classified data.
Separate devices into department, administrative, or other functional group.
Zoning divides the fabric for purposes of controlling discovery and inbound traffic.
A zone is a named group of ports or devices. Members of the same zone can
communicate with each other and transmit outside the zone, but cannot receive
inbound traffic from outside the zone. Zoning is hardware-enforced only when a
port/device is a member of no more than eight zones whose combined
membership does not exceed 64. If this condition is not satisfied, that port
behaves as a soft zone member. You can assign ports/devices to a zone
individually or as a group by creating an alias.

A zone can be a component of more than one zone set. Several zone sets can be
defined for a fabric, but only one zone set can be active at one time. The active
zone set determines the current fabric zoning.

A zoning database is maintained on each switch.
