FlowPointIdentifier
This textual convention denotes an octet string-value that identifies a point at which a flow monitor collects data for a traffic flow. An implementation MUST ALWAYS interpret a FlowPointIdentifier value within the context of a FlowPointType value. Every use of the FlowPointIdentifier textual convention requires the specification of a FlowPointType object to provide the context. A MIB module SHOULD logically register the FlowPointType object before the FlowPointIdentifier object(s). The value of a FlowPointIdentifier object MUST BE the null string if the value of the FlowPointType object providing the context is 'unknown' or 'none'. Implementations must ensure that a FlowPointIdentifier object remains consistent with the FlowPointType object providing the context. For example, an implementation must respond with an 'inconsistentValue' error if an attempt is made to modify a FlowPointIdentifier object without changing the corresponding FlowPointType object.
