Once an AP and an algorithm has been selected, all the virtual devices within that algorithm are initialized to best-guess ``healthy'' states for convenience. At any time all devices can be returned to this initial state by selecting the ``INIT ALL'' button. The ``GET FROM MPS'' button is a future option, not yet supported, that will update the devices in the list to their actual states on the currently running MPS system.
A scrollable list of devices and their corresponding states (or list of APs and their corresponding rates and MPSTs and their states if the selected AP is a supervisor) is presented on the left half of the overlay. To change a device to a different state, select the operand-equality of interest. A list of the possible states of the device (and their respective severities) will appear in the window titled ``states - severities''. Selection of one of these states will cause the virtual device to be updated to that state, and this information will be reflected in both the ``operand-equalities'' window and the error messages window.
To set stopper configurations, devices must be set the the states appropriate for them.
At any time during this configuration process you have the option to save the current device configuration to a file. Select the ``SAVE TO FILE'' button, and a familiar file selection set of windows will pop up. Select a file as you did an algorithm, and you can pop down this set of windows by selection of either of the ``SAVE TO FILE'' or ``GET FROM FILE'' buttons. You can then recall the device configuration for this simulation and any future one for this MPS algorithm by selecting the ``GET FROM FILE'' button and following the same procedure used to save this data.
Once all the devices are configured as desired you can pop down the operand-equality configuration overlay and work on other overlays and panels.
