Some zoning strategies are: • Separating devices by operating system • Separating devices that have no need to communicate with other devices in the fabric or have classified data • Separating devices into department, administrative, or other functional group • Reserving a path and its bandwidth from one port to another 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 divides the fabric for purposes of controlling discovery and inbound traffic. 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. Displaying zoning database information A switch maintains three zoning databases: • Non-volatile-This zoning database is permanent and contains all zone sets, zones, and aliases that you create and save on a switch. The zone sets in the non-volatile zoning database are known as configured zone sets. • Volatile-This zoning database is temporary. This means it is not retained across switch resets. The volatile zoning database can be the working copy of a zone set being edited or an active zone set received from another switch. In the latter case, this is also known as the merged zone set. • Active-This zoning database is the active zone set. You can display the following information about the zoning database: • Configured zone set information, page 72 • Active zone set information, page 73 • Merged zone set information, page 74 • Edited zone set information, page 74 • Zone set membership information, page 74 • Orphan zone information, page 75 • Alias and alias membership information, page 76 • Zoning modification history, page 76 • Zoning database limits, page 77 8/20q Fibre Channel Switch command line interface guide 71

Access to devices within the fabric is controlled by zoning. Some zoning strategies are:
Separating devices by operating system
Separating devices that have no need to communicate with other devices in the fabric or have
classified data
Separating devices into department, administrative, or other functional group
Reserving a path and its bandwidth from one port to another
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 divides the fabric for purposes of controlling discovery and inbound traffic. 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.
Displaying zoning database information
A switch maintains three zoning databases:
Non-volatile—This zoning database is permanent and contains all zone sets, zones, and aliases that
you create and save on a switch. The zone sets in the non-volatile zoning database are known as
configured zone sets.
Volatile—This zoning database is temporary. This means it is not retained across switch resets. The
volatile zoning database can be the working copy of a zone set being edited or an active zone set
received from another switch. In the latter case, this is also known as the merged zone set.
Active—This zoning database is the active zone set.
You can display the following information about the zoning database:
