4. Issue either the cfgSave, cfgEnable, or cfgDisable command to commit the change and
distribute it to the fabric. The change will not be committed and distributed across the fabric if you do
not issue one of these commands.
Viewing the current default zone access mode
To view the current default zone access mode:
1. Connect to the switch and log in as admin.
2. Issue the defZone
--show command.
NOTE: If you performed a firmware download of an older release, the current default zone access state
will appear as it did prior to the download. For example, if the default zoning mode was No Access before
the download, it will remain as No Access afterward.
See the Fabric OS Command Reference for additional information on the defZone command.
Zone database size and zone merging Merging zones
Table 57 presents zoning database size limitations for various Fabric OS release versions. The maximum
size of a zone database is the upper limit for the defined configuration, and it is determined by the amount
of flash memory available for storing the defined configuration.
Before linking two switches together, it is important that you know the zone database limit of adjacent
switches. For example, when switches running Fabric OS 3.2, 4.4.0, or 5.1.0 discover that the zone merge
database is larger than its pre-determined zone database size limit, they issue a reject notification before
symmetrically segmenting their own ends of the ISL, thereby preventing the new switch from joining the
fabric.
NOTE: Fabric OS 5.2.0 and later support a zoning database size of 1 MB. To support a 1 MB zoning
database, the entire fabric must be upgraded to 5.2.0 or later. If any pre-5.2.0 switches are part of the
fabric, the maximum zone database size is 256 KB. If the zoning database size exceeds 256 KB, switches
not upgraded to Fabric OS 5.2.0 or later are segmented out of the fabric. Use the cfgSize command to
display the zoning database size.
