For instance, status_port status:gps will display only the GPS status variables instead of all the variable.

    DOC 6511_Release K ATS-6511A/B/C Users Guide Appendix E System Configuration (syscfg) This system configuration (syscfg) is a method of documenting the system (ATS-65XX) series devices and having the unit alert the operator when the system settings differ from the configuration file either by card or by port settings. Once set up and enabled the system will alert the operator if someone puts a card in the wrong slot, installs a card that does not belong in the chassis and if a port setting is incorrect (i.e PPS and IRIG).
