both | initiator | target } }
undo fc wwn wwn-value default-fc4-type { type-value | scsi-fcp }
Default
No default FC4 information is configured.

Parameters
wwn-value: Specifies a node by its WWN in the format of xx:xx:xx:xx:xx:xx:xx:xx (hexadecimal).
type-value: Specifies a supported FC4-Type by its value in the range of 0 to 255. The FC4-Type field is
256 bits, each of which represents an FC4-Type. If a bit is set to 1, the FC4-Type that the bit represents
is supported. Only one bit can be set to 1 at the same time.
scsi-fcp: Specifies the supported FC4-Type as SCSI-FCP, which has a type-value of 8.
feature feature-map: Specifies the Feature value for the supported FC4-Type. The value range for
feature-map is 0 to 15. The Feature field is 4 bits, each of which represents a Feature. If a bit is set to 1,
the Feature that the bit represents is supported. More than one bit can be set to 1 at the same time. For
example, if the value is set to 15, the node supports four features of the FC4-Type. If the value is set to 0,
the node supports none of the four features. When you specify supported FC4-Type as SCSI-FCP, you can
configure the following keywords:
initiator: Specifies support for the initiator feature, which has a feature-map of 2.
•
• target: Specifies support for the target feature, which has a feature-map of 1.
both: Specifies support for both initiator and target features, which has a feature-map of 3.
•
Usage guidelines
If a node does not register FC4 information and the switch fails to obtain SCSI-FCP information from the
node, the switch records the default FC4 information in the name service database for that node. When
a node registers FC4 information or the switch obtains the SCSI-FCP information, the switch replaces the
default FC4 information with the registered FC4 information or obtained SCSI-FCP information.
This command can be used to configure only one combination of FC4-Type and Feature at a time.
Examples
# Configure the default FC4 information for the node with WWN 00:00:00:1 1:22:33:44:55.
