Two interfaces are provided; SNMP and an HTTP Web-based interface. NOTE. The DTV Monitor Programmer Interface MIB file accompanying this document contains entries not described in the manual. These entries should not be used.

There are essentially three types of operations that can be performed on each object: H Get. Retrieves the value of an object. H GetNext.

So when a management system subscribes to trap messages, this is only for a few minutes. The management system must repeatedly subscribe in order to continue to receive trap messages. This provides protection in the case of a management system exiting improperly.

The ‘table_entry_oid’s within the DTV Monitor MIB are always given the value 1, and are not shown on the structure charts within this document because it would complicate the diagrams.

  • Page 89: Mpeg Trap Control

    MPEG Structure MPEG Trap Control The trap control group provides the variables to support the traps sent and the configuration items to control trap generation. Clients subscribe to traps by writing their IP address into trapSink; they are automatically deleted from the notification list after trapSinkTimeout minutes. So a client should subscribe every few minutes.

TrapSinkTimeout Integer Minutes before unsubscribing trap client, 0 is infinite. trapRemoveSink IpAddress Removes IP Address of Client to be sent traps.
