Protocol free testing of a fabric switch

摘要

A switch fabric for a modular router may be tested without connecting the switch fabric portion of the router to the other modular portions of the router. The switch fabric may generate test data units and insert the test data units into one or more elements of the switch fabric. The switch fabric may operate with the inserted test data units. A control component may receive data units from the switch fabric after operation of the switch fabric and analyze the received data units to determine whether the received data units correspond to the inserted test data units.

主权项

1. A method comprising:
freezing, by a device, an operation of a switch fabric while data units are inserted into the switch fabric; unfreezing, by the device, the operation of the switch fabric after the data units are inserted into the switch fabric; reading, by the device and after unfreezing the operation of the switch fabric, one or more of the data units previously inserted into the switch fabric; determining, by the device, one or more results by comparing a bit pattern of the one or more of the data units read from the switch fabric to a bit pattern originally present in the data units; and outputting, by the device, the one or more results.
