Abstract

An apparatus for assigning a device to a network zone comprises a switch component operable to receive an attachment request, port and device name data and device operating characteristics data from the device; and a rules engine operable to acquire the device operating characteristics data from the switch component; the rules engine being operable to apply rules logic to the device operating characteristics data to select a zone for the device. The rules engine may be further operable to apply the rules logic to the port and device name data. The network zone may be a network zone of a fiber channel network.
