113: -- Objects pointed to by StaticRowPointers, parameterization
114: -- table entries, can be reused by one or more data path
115: -- functional elements in one or more TCBs, belonging to one
116: -- or more data paths.

122: StaticRowPointer ::= TEXTUAL-CONVENTION
123: STATUS current
124: DESCRIPTION
125: "Like a RowPointer, this textual convention
126: represents a pointer to a conceptual row. The value
127: is the name of the instance of the first accessible
128: columnar object in the conceptual row.
129:
130: The additional semantics of this textual convention,
131: relative to RowPointer, are related to the object the
132: pointer is pointing to. The pointed-to object may
133: have more than one parent object pointing to it,
134: indicating the pointed-to object can be shared by one
135: or more parent objects.
136:
137: This additional semantics facilitates the creation of
138: instance-specific objects by cloning, used by higher
139: level configuration/provisioning mechanisms. The
140: objects being cloned may either be special ones that
141: express configuration information at the
142: implementation-specific level, or simply instance-
143: specific ones that already exist at the time the
144: cloning is done. When an object with the syntax Sta-
145: ticRowPointer is cloned, the StaticRowPointer in the
146: newly cloned object is set to point to the same con-
147: ceptual row that the StaticRowPointer in the cloned-
148: from object pointed to. The cloning operations may be
149: accomplished either with the script-based technique
150: defined by SNMP Configuration, or by ordinary SNMP
151: Get and Set operations, or other mechanisms.
152:
153: Support of this additional semantics and cloning
154: functionality is not required for conformance to this
155: MIB. When the additional semantics is not supported,
156: this textual convention behaves identically to the
157: RowPointer textual convention."
