WDM Wavelength division multiplexer. A set of technologies that allows multiple
wavelengths to be combined or filtered on a single cable.
See DWDM.
well-known ad- In Fibre Channel technology, a logical address defined by Fibre Channel
dress standards, as assigned to a specific function and stored on the switch.
workstation A computer used to access and manage the fabric. Also called management
station or host.
WTV Write timeout value. An ELS field that appears in portLogDump command
output.
WWN World Wide Name. An identifier that is unique worldwide. Each entity in a
fabric has a separate WWN.
WWN-level zon- This type of zoning defines a zone member using a WWW port or a WWN
ing
node. Defining a zone member with a WWN allows the member (device) to
be attached without regard to its physical location.
X.25 A protocol that uses logical channels. X.25 allows high-quality communications
between computers and can accommodate noisy data communications through
error-detection and error-correction (retransmission) algorithms.
zone A collection of Fibre Channel N_Ports and NL_Ports ( device ports) that are
allowed to communicate with each other via the fabric. Any two N_Ports and
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:
•
•
•
•
Well-known addresses are implicitly included in every zone. Devices and hosts
within the same zone have access to others in the zone but are not visible to
any outside the zone.
zone configuration A specified set of zones. Enabling a configuration enables all zones in that
configuration.

zone
zone configuration Defines a list of zone objects. The zone database can contain several zone
object configuration objects, but only one zone configuration object can be enabled
and enforced at a time.
See also
zone member The specification of a device to be included in a zone. A zone member may be
defined as a port on a switch or a World Wide Name. A zone member can
belong to more than one zone at a time.
See also
zone object Defines a list of zone members. A zone object can exist across multiple zone
configuration objects.
zoning A feature in fabric switches or hubs that allows segmentation of a node by
physical port, name, or address.
