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.
There are two configuration parameters that affect the zoning database: Interop Auto Save and Default Visibility. 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. The Default Visibility parameter permits or prohibits communication among ports/devices when there is no active zone set. Refer to “Configuring the Zoning Database” on page
The following zoning limits are enforced during the configuration of zoning and during a zoning database merge from the fabric:
MaxZoneSets is 256. The maximum number of zone sets that can be configured on the switch.
MaxZones is 2000. The maximum number of zones that can be configured on the switch.
MaxAliases is 2500. The maximum number of aliases that can be configured on the switch.
MaxTotalMembers is 10,000. The maximum number of total zone and alias members that can be configured on the switch. Aliases are considered zone members since they can be added to a zone just like a normal zone member.
MaxZonesInZoneSets is 2000. The maximum number of zone linkages to zonesets that can be configured on the switch. Every time a zone is added to a zoneset this constitutes a linkage.
MaxMembersPerZone is 2000. The maximum number of zone members that can be added to any zone on the switch. Aliases are considered zone members when added to a zone.
MaxMembersPerAlias is 2000. The maximum number of zone members that can be added to any alias on the switch.
