An Inter-Chassis Link (ICL) failure management system includes a first switch device and a second switch device coupled together by an Inter-Chassis Link (ICL) that is included in a control network and that is configured to provide a primary control channel for transmitting control information between the first switch device and the second switch device. A third switch device is coupled to each of the first switch device and the second switch device by a first aggregated link. When the first switch device determines that the ICL is unavailable, it causes a first port and a second port that provide the first aggregated link to be added to the control network to provide a primary backup control channel. The first switch device may then send control information to the second switch device through the primary backup control channel via the first port and the second port.
