SmonDataSource
Identifies the source of the data that the associated function is configured to analyze. This Textual Convention extends the DataSource Textual Convention defined by RMON 2 to the following data source types: - ifIndex.<I> DataSources of this traditional form are called 'port-based', but only if ifType.<I> is not equal to 'propVirtual(53)'. - smonVlanDataSource.<V> A dataSource of this form refers to a 'Packet-based VLAN' and is called a 'VLAN-based' dataSource. <V> is the VLAN ID as defined by the IEEE 802.1Q standard [19]. The value is between 1 and 4094 inclusive, and it represents an 802.1Q VLAN-ID with global scope within a given bridged domain, as defined by [19]. - entPhysicalEntry.<N> A dataSource of this form refers to a physical entity within the agent (e.g. entPhysicalClass = backplane(4)) and is called an 'entity-based' dataSource.
