Abstract
A multi-chassis network device may automatically detect whether cables connected between chassis devices are correctly inserted. The device may insert, into a first data stream output from a first port of the device, control information identifying the first port. The device may receive, from a second data stream received by the first port of the device, second control information identifying a second port, at another device connected to the device via a cable. The device may determine, based on the second control information, whether the connection of the first port to the second port, via the cable, is valid and cause, when the connection of the first port to the second port is determined to not be valid, the device to output an indication that the connection is not valid or to reconfigure the device to make the connection of the first port to the second port valid.
