dataSourceCapsTable 1.3.6.1.2.1.16.22.1.1.1

This table describes RMON data sources and port copy capabilities. An NMS MAY use this table to discover the identity and attributes of the data sources on a given agent implementation. Similar to the probeCapabilities object, actual row-creation operations will succeed or fail based on the resources available and parameter values used in each row-creation operation. Upon restart of the RMON agent, the dataSourceTable, ifTable, and perhaps entPhysicalTable are initialized for the available dataSources. For each dataSourceCapsEntry representing a VLAN or entPhysicalEntry the agent MUST create an associated ifEntry with a ifType value of 'propVirtual(53)'. This ifEntry will be used as the actual value in RMON control table dataSource objects. The assigned ifIndex value is copied into the associated dataSourceCapsIfIndex object. It is understood that dataSources representing VLANs may not always be instantiated immediately upon restart, but rather as VLAN usage is detected by the agent. The agent SHOULD attempt to create dataSource and interface entries for all dataSources as soon as possible.
