zone: A collection of Fibre Channel N_Ports and/or NL_Ports (i.e., device ports) that are permitted to communicate with each other via the fabric. Any two N_Ports and/or NL_Ports that are not members of at least one common zone are not permitted to communicate via the fabric. Zone membership may be specified by:
port location on a switch, (i.e., Domain_ID and port number); or,
the device's N_Port Name; or,
the device's address identifier; or,
the device's Node_Name.
Well-known addresses are implicitly included in every zone. cf. zone set.
