The value of tmnxDot1agCfmMepSlmOWTestStatus specifies the operational
state of the one-way Synthetic Loss Measurement (SLM) test.
To issue a one-way SLM test the user must issue an SNMP SET on this
object with a value 'enabled (1)'. To abort the one-way SLM test issue
an SNMP SET on this object with the value 'disabled (2)'.
A read on this object represents the current state of the one-way SLM
test:
enabled (1) - The test is actively running, and attempts at
modifying any one-way SLM object will be rejected
disabled (2) - The test is not running.
Once the test is complete this object will revert to the default value
'disabled (2)'.
