摘要：A “high availability” system comprises multiple switches under the control ofa control processor (“CP”). The firmware executing on the processor can be changedwhen desired. Consistent with the high availability nature of the system (i.e., minimal down
time), a single CP system implements a firmware change by loading new firmware ontothe system, saving state information pertaining to the old firmware, preventing the oldfirmware from communicating with the switches, bringing the new firmware to an activestate and applying the saved state information to the new firmware.
