1 DEREGISTER ! Remove a node registration from a directory service. DEREGISTER [DECNET] NODE node-id [ DIRECTORY_SERVICE dir-service ] [ PHASEIV_PREFIX addr-prefix ] [ REVERSE_DIRECTORY rev-dir-name ] [ SYNONYM_DIRECTORY syn-dir-name ] This is used when a node is no longer available in the network, and the node registration needs to be removed from a directory service. ! 2 NODE ! This specifies the identification of the node to be de-registered. NODE node-id The node identification can be one of: The fully specified name for the node in the directory service. The Phase IV synonym for the node. One of the NET or NSAP addresses for the node. The Phase IV address (and optional Phase IV prefix) for the node. Wildcards are allowed in names and addresses. ! 3 Names ! The node to be de-registered can be specified using its full name or its Phase IV synonym. The syntax of a fully specified name depends on the directory service being used. Examples of fully specified names might be: For Local: NODE MailHub For DECdns: NODE MyCo:.Sales.MailHub For Phase IV: NODE MLHUB An example of a Phase IV synonym for any of the above might be: NODE MLHUB Wildcards are allowed in the node name using an asterisk (*). For example: For Local: NODE Mail* For DECdns: NODE MyCo:.Sales.Mail* For Phase IV: NODE ML* The wildcard character can come anywhere in the last part of the name. Only a single wildcard character is allowed. ! 3 Addresses ! The node to be de-registered can be specified using one of its NETs (or NSAPs), or its Phase IV address. An NET is an NSAP address value with an N-Sel value of "00" (indicating that it is independent of the type of transport service in use on the node). If you specify an NSAP instead of an NET, it is converted to an NET before it is used. DNA format: ::-::00 OSI format: +00 Examples of NETs might be: DNA format: NODE 39:840:0001:AA-00-04-00-05-04:00 OSI format: NODE 39840+0001AA000400050400 If the node has a Phase IV address, that can be used instead of an NET. Format: . .+ This is internally converted to an NET, using the Phase IV prefix value. The Phase IV prefix value can be specified with the Phase IV address or the PHASEIV_PREFIX parameter, or set using the SET DEFAULT command. Examples of a Phase IV address might be: NODE 1.5 Uses the default Phase IV prefix NODE 1.5+39:840 Uses an explicit Phase IV prefix NODE 1.5 PHASEIV_PREFIX 39:840 Uses an explicit Phase IV prefix Wildcards are allowed in the NET or Phase IV address using an asterisk. The wildcard character must replace either the node id, or the local area and the node id. For an NET containing a wildcard, do not specify an N-Sel value. 39:840:0001:* (or 39840+0001*) Wildcard the node id 39:840:* (or 39840+*) Wildcard the local area and node id 1.* Wildcard the node id *.* Wildcard the area and node id ! 2 DIRECTORY_SERVICE ! This specifies the directory service that contains the node registration. DIRECTORY_SERVICE dir-service The service must be one of: DIRECTORY_SERVICE LOCAL DIRECTORY_SERVICE DECDNS DIRECTORY_SERVICE PHASEIV If not specified, the default service type is used. This default can be displayed or changed using the SHOW or SET DEFAULT commands. ! 2 PHASEIV_PREFIX ! This specifies the AFI, IDI, and preDSP to use when constructing an NET from a Phase IV address. This is used only when a Phase IV address is specified for the node id. PHASEIV_PREFIX addr-prefix An alternate form is to add the Phase IV prefix to the Phase IV address specification. For example, both: NODE 1.5 PHASEIV_PREFIX 39:840:800AB738 NODE 1.5+39:840:800AB738 result in the following NET being used to represent the DECnet Phase IV address: 39:840:800AB738-0001:AA-00-04-00-05-04:00 If not specified, the default Phase IV prefix is used. This default can be displayed or changed using the SHOW or SET DEFAULT commands. See the PHASE_IV_PREFIXES topic for details about Phase IV prefix values. ! 2 REVERSE_DIRECTORY ! This specifies the base directory or name entry to use when deleting the reverse address mapping links to the node name (also called the back translation links). REVERSE_DIRECTORY rev-dir-name The links under this directory are used to map NSAP values to their respective node names. These directories are used only for the DECdns directory service. If not specified, the default reverse directory is used. This default can be displayed or changed using the SHOW or SET DEFAULT commands. See the NAMES_AND_DIRECTORIES topic for more information on directories. ! 2 SYNONYM_DIRECTORY ! This specifies the base directory or name entry to use when deleting the synonym mapping link to the node name. SYNONYM_DIRECTORY syn-dir-name The links under this directory are used to map Phase IV synonyms to their respective node names. These directories are used only for the DECdns directory service. If not specified, the default synonym directory is used. This default can be displayed or changed using the SHOW or SET DEFAULT commands. See the NAMES_AND_DIRECTORIES topic for more information on directories. !
