This object is used to start or retry a test or delete an entry. The possible values that can be written are: startTestSourceRoute(2)...Start a path test for networks using source routing bridging. startTestTransparent(3)...Start a path test for networks using transparent bridging. retryTestSourceRoute(4)...Retry the path test for networks using source routing bridging. retryTestTransparent(5)...Retry the path test for networks using transparent bridging. clearTest(6)..........Delete an entry. The possible values that can be read are: other(1) none of the following. startTestSourceRoute(2)...Indicates a path test for networks using source routing bridging has been started. startTestTransparent(3)...Indicates a path test for networks using transparent bridging has been started. retryTestSourceRoute(4)...Indicates the path test for networks using source routing bridging has been retried. retryTestTransparent(5)...Indicates the path test for networks using transparent bridging has been retried. If s5TrTestTpStart is set to startTestTransparent(3) or retryTestTransparent(5), the value of s5TrTestTpRoute is ignored. A TEST command PDU without source routing information will be sent by the agent. If s5TrTestTpStart is set to startTestSourceRoute(2) or retryTestSourceRoute(5) and the value s5TrTestTpRoute is a zero length string, a single-route broadcast TEST command PDU will be sent to explore the route from the agent to s5TrTestTpAddrTo. If s5TrTestTpRoute contains some specific route, the agent will send a nonbroadcast TEST command PDU to check this route. If a test between the station identified by the object s5TrTestTpStart and the agent has already been started (so the s5TrTestTpStatus has value testInProgress(2)), the agent will return 'no error' to the SNMP SET request of a start or retry value. However, the agent will not initiate a new TEST command PDU. If the test cannot be started because of errors in the SET request, or because of some limitations on the agent side (e.g., the table limit has been exceeded), then the response to the SET request will be SNMP 'bad value' or 'general' error. For both start-test and retry-test the age-out time for the entry will be refreshed (i.e., as if the entry was just created).
