Zoning a Fabric

3.4.1.2
Aliases
To make it easier to add a group of ports or devices to one or more zones, you can
create an alias. An alias is a named set of ports or devices that are grouped
together for convenience. Unlike zones, aliases impose no communication
restrictions between its members. You can add an alias to one or more zones.
However, you cannot add a zone to an alias, nor can an alias be a member of
another alias.
3.4.1.3
Zone Sets
A zone set is a named group of zones. A zone can be a member of more than one
zone set. All zones that are not members of a zone set belong to the orphan zone
set. The orphan zone set is saved on the switch. Each switch in the fabric
maintains its own zoning database containing one or more zone sets. This zoning
database resides in non-volatile or permanent memory and is therefore retained
after a reset. Refer to ”Configured Zonesets Data Window” on page 4-14 for
information about displaying the zoning database.
To apply zoning to a fabric, choose a zone set and activate it. When you activate a
zone set, the switch distributes that zone set and its zones, excluding aliases, to
every switch in the fabric. This zone set is known as the active zone set. Refer to
”Active Zone Set Data Window” on page 3-13 for information about displaying the
active zone set.
3.4.1.4
Zoning Database
Each switch has its own zoning database. The zoning database is made up of all
aliases, zones, and zone sets that have been created on the switch or received
from other switches. The switch maintains two copies of the inactive zoning
database: one copy is maintained in temporary memory for editing purposes; the
second copy is maintained in permanent memory. Zoning database edits are
made on an individual switch basis and are not propagated to other switches in
the fabric when saved.
The zoning limits for a fabric are as follows:
MaxZoneSets is 256. The maximum number of zone sets that can be
configured on the switch. This will be enforced during the configuration of
zoning and during a zoning database merge from the fabric.
MaxZones is 256. The maximum number of zones that can be configured
on the switch. This will be enforced during the configuration of zoning and
during a zoning database merge from the fabric.
MaxAliases is 256. The maximum number of aliases that can be configured
on the switch. This will be enforced during the configuration of zoning and
during a zoning database merge from the fabric.
