This specifies the delay, in minutes, between consecutive delay-measurement test iterations (0 to 1440, i.e. up to a full day), as explicitly stated in the description, controlling how spread out repeated test cycles are rather than running back-to-back with no gap. An admin sets a larger repeat delay to spread test traffic overhead out over a longer period when monitoring a production service continuously, rather than generating DMM probe bursts too frequently. For example, cienaCesCfmDelayMsgRepeatDelay set to 60 would run one iteration of the delay test every hour, rather than repeating immediately after each iteration finishes.
