When the active-sim command is set to auto and at least one failure criterion is configured, the system uses the length of time configured for the failure-duration to determine when to perform an automatic failover from one SIM to the other.
The failure-duration value is configured per SIM but it applies to all failure criteria. It is not possible to configure one failure duration value for one criterion and another failure duration value for another criterion.
The default value is 5 minutes. The valid range is from 1 minute to 60 minutes.
It is recommended that the failure-duration be set to a high value so that the system does not perform frequent switches between SIMs.
