Default visibility
The Default Visibility parameter determines the level of communication that is permitted between devices when there is no active zone set. The default visibility parameter can be set differently on each switch module. When default visibility is enabled (set to All) on a switch module, all ports on the switch can communicate with all ports on switch modules that also have the Default Visibility parameter set to Enabled. When default visibility is disabled (set to None) on a switch module, none of the ports on that switch module can communicate with any other switch in the fabric.
Using the Zoning Config window
Use the Zoning Config window to change the Auto Save and Default Visibility configuration parameters. Complete the following steps to open the Zoning Config window and change configuration parameters:
1.In the Faceplate window, click Zoning ” Edit Zoning Config.The Zoning Config window opens.
Figure 10. Zoning Config window
2.Make the necessary changes to the Auto Save and Default Visibility fields and click OK.
Restoring default zoning
Restoring the default zoning clears the switch module of all zoning definitions. Complete the following steps to restore the default zoning for a switch module.
Attention: The use of this command will deactivate any active zone set. If the switch module is not isolated from the fabric, this command will deactivate the active zone set for the entire fabric.
1.In the Faceplate window, click Zoning ” Restore Default Zoning.
2.Click OK to confirm that you want to restore default zoning and save changes to the zoning database.
Merging fabrics and zoning
If you join two fabrics, the active zone sets from the two fabrics attempt to merge. The fabrics can consist of a single switch module or many switches already connected together. The switch modules in the two fabrics attempt to create a new active zone set containing the union of the active zone set of each fabric. The propagation of zoning information affects only the active zone set, not the configured zone sets.
Zone merge failure
If a zone merge is unsuccessful, the interswitch links between the fabrics will isolate because of a zone merge failure, which generates an alarm log entry. The reason for the E_Port isolation can also be determined by viewing the port information. See the “Port Information Data window” on page 102 and the “Show command” on page 42 (Port keyword).
