The value of the object tmnxCallTracePrimaryCFlash specifies the compact flash card to be used as the primary local storage location to save the generated call trace log files. The system will write to the specified compact flash card until the size of all generated files reaches the limit defined by the value of the object tmnxCallTraceLocationSizeLimit for the given compact flash card and the card is not disabled as the local storage location by the value of the object tmnxCallTraceLocationDisable. Once the limit is reached or the card is disabled the files will be written to the other compact flash card. The compact flash card must be available in the system in order to select it as the primary storage location. If the card is not available at the moment of SNMP SET operation, the other card is automatically selected as the primary location.
