Zoning database
Each switch has its own zoning database. The zoning database is made up of the active zone set that has
been created on the switch or received from other switches. The switch maintains two copies of the 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. When a zone set is activated, it is propagated
and saved to temporary memory in each switch in the fabric. If a switch has the Interop Auto Save
parameter is enabled in the Zoning Config dialog, the zone set is saved to permanent memory on that
switch.
NOTE: If the Interop Auto Save parameter is enabled on the Zoning Configuration dialog, then every time
the active zone set changes, the switch will copy it into an inactive zone set stored on the switch. You can
edit this copy of the active zone set stored on the switch, and activate the updated copy to conveniently
apply the changes to the active zone set. The edited copy then becomes the active zone set.
The Interop Auto Save parameter determines whether changes to the active zone set that a switch receives
from another switch in the fabric will be saved to permanent memory on that switch. See ”Configuring the
zoning database” on page 56 for information about zoning configuration.
Viewing zoning limits and properties
Zoning limits vary depending on the firmware installed on the switch. To view zoning limits and properties
on a switch, perform the following procedure:
1. Select Zoning > Edit Zoning in the faceplate display to open the Edit Zoning dialog.
2. Choose one of the following:
• Right-click on the top zonesets entry, a zone set, a zone, or a zone member in the zone sets tree (left
windowpane). Select Properties in the popup menu.
• Select the top zone sets entry, a zone set, a zone, or a zone member in the zone set tree (left
windowpane). Select Edit > Properties.
3. View the zoning limits and properties information in the Properties dialog.
4. Click OK to close the Properties dialog.
The zoning limits and definitions are:
• MaxZoneSets is 1. 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 2047. 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.
• MaxTotalMembers is 10,000. The maximum number of total zone members 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.
• MaxZonesInZoneSets is 2047. The maximum number of zone linkages to 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. Every time a zone is added to a zone set this constitutes a linkage.
• MaxMembersPerZone is 10,000. The maximum number of zone members that can be added to any
zone on the switch. This will be enforced during the configuration of zoning and during a zoning
database merge from the fabric.
