An aggregated networking device maintenance system includes a first aggregated networking device and a second aggregated networking device that are coupled together, and each coupled to a third networking device. The first aggregated networking device receives a maintenance instruction and, in response, transmits a first maintenance notification message to the second aggregated networking device, and a second maintenance notification message to the third networking device that prevents the third networking device from transmitting data traffic to the first aggregated networking device. Maintenance operations on the first aggregated networking device may then be performed, and when the first aggregated networking device determines that the maintenance operations have completed, it transmits a first maintenance completed notification message to the second aggregated networking device, and a second maintenance completed notification message to the third networking device that causes the third networking device to resume transmitting data traffic to the first aggregated networking device.
