Abstract:
1. A method, comprising: providing a pair of interconnected, related network devices, each being operable in a testing operation to function as both a Device Testing Doctor (DTD) and a Device Under Test (DUT), each having a programmable central processing unit (CPU) and a memory operable to receive, store and output testing code; storing testing code in each of the respective memories of the two devices, the testing code comprising: with one of the devices functioning as the DTD and the other device functioning as the DUT in the testing operation: loading selected ones of the device configurations from the DTD to the DUT; transmitting selected ones of the input traffic patterns from the DTD to the DUT; comparing the output of the DUT in response to the input traffic patterns with selected ones of the standard-behavior-output templates; and, detecting a network device defect or bottleneck in the DUT based on the comparison.
