Abstract:
1. A method, comprising: logging on to a storage area network and receiving a list of all switches and paths from a testing device to end devices to be tested; interrogating each link and port from the testing device to the end devices to determine a failing link or port; issuing at least one echo extended link service command including a frame with a payload of data patterns to an end device to be tested, wherein the echo extended link service command is used to send data with a specified data pattern upon logging on to the end device; re-interrogating each link and port from the testing device to the end devices to determine a failing link or port; recording results based on the echo link service command, logging errors encountered during each testing cycle, recording a failed data pattern associated with each logged error, and comparing the failed data pattern against a library of data patterns known to create jitter; and determining whether a jitter condition or jitter indication has been detected and transmitting results from the comparing to a user.
