SWITCH FABRIC TESTING |
摘要 |
A method is presented which allows for the testing and verification of an of f- line switch fabric used in network switch having redundant switch fabrics. A special test cell is directed to the off-line switch fabric, loops through a portion of the switching core of the off-line switch fabric, and is returned from the off-line switch fabric. A plurality of test cells can be used to provide full mesh connectivity checking of the off-line switch fabric. Testing is accomplished without need for reconfiguration of the off-line switch fabric, and the off-line switch fabric is available for use immediately upon determinati on of the need therefor.
