# Restoring Default Zoning

Resetting the default zoning clears the switch of all zoning definitions and then creates and activates the default zone set. The default zone set name has the format zone_set_#, where # is the SANbox Manager switch slot number. The member zone names have the format zone_DID_N, where DID is the domain ID, and N is a sequence increment. No default zoning is defined for DS-16A switches that provide for free communication among all ports.

Caution: The use of this procedure will deactivate any active zone set. If the switch is not isolated from the fabric, this procedure will deactivate the active zone set for the entire fabric.

To restore the default zoning for a switch, do the following:

1. In the faceplate display, open the Zoning menu and select Restore Default Zoning.

2. Click the OK button to confirm that you want to restore default zoning and save changes to the zoning database.
