This writable parameter controls whether a Cisco RTT (Round Trip Time) monitoring probe runs on a daily recurring schedule, executing automatically at the same time each day for the configured duration. The parameter cannot be set to true if the scheduled duration is 24 hours or longer, or if the sum of the probe lifetime and concept row ageout time equals or exceeds 24 hours. Network administrators use this setting to schedule continuous performance monitoring operations without manual intervention while respecting system constraints.
