This object specifies the type of start time of the SOAM LM
session. The start time can be disabled (none), immediate, relative,
or fixed.
The value of 'none' is illegal and a write error will be returned
if this value is used.
The value of 'immediate' starts the SOAM LM session when the
jnxSoamLmCfgEnabled is true.
The value of 'fixed' starts the SOAM LM session when the
jnxSoamLmFixedStartDateAndTime is less than or equal to the current
system date and time and jnxSoamLmCfgEnabled is true. This value is used
to implement an On-Demand fixed time PM session.
The value of 'relative' starts the SOAM LM session when the current
system date and time minus the jnxSoamLmRelativeStartTime is greater
than or equal to the system date and time when the jnxSoamLmStartTimeType
object was written and jnxSoamLmCfgEnabled is true. This value is used
to implement an On-Demand relative time PM session.
This object can only be written at row creation time and cannot be
modified once it has been created.
