Abstract
A method and system for testing a Layer tunnel in a data communication network including a network device and a network manager are described. According to the method, a test invocation is received from the network manager at the network device. In response to receipt of the test invocation at the network device, a Layer tunnel within the data communication network is tested, and a result of the test is reported to the network manager. The tests that may be conducted include a connectivity test to determine if a Layer tunnel can be established and a responsiveness test to determine the propagation time of a Layer tunnel. Advantageously, both compulsory and voluntary Layer- tunnels can be tested, thereby enabling all Layer protocols (e.g., L TP, L F, and PPTP) to be supported.
