Hibernation wake mechanism on a stack of switches using stacking links

A commander device in a stack of network devices, the commander device comprising:

• at least one processing resource;
• a plurality of ports;
• and
• a storage device storing instructions which when executed by the at least one processing resource cause the at least one processing resource to execute the instructions to:
• receive a notification indicating that the commander device is to wake up from a hibernation state;
• boot up in response to receiving the notification;
• transmit a wake-up signal as an energy pulse detectable based on a width and amplitude associated with the energy pulse to a first member device of the stack of network devices via a first stacking link coupling to the first member device;
• and
• allow the first member device to boot up from the hibernation state in response to receiving the energy pulse on the first stacking link and transmit the wake-up signal as the energy pulse detectable based on the width and amplitude associated with the energy pulse to a second member device via a second stacking link coupling to the second member device.

A stack of network devices, comprising:

• a commander device comprising at least one first processor and at least one first non-transitory computer-readable medium storing first instructions;
• and
• one or more member devices, wherein a respective member device comprises at least one second processor and at least one second non-transitory computer-readable medium storing second instructions;
• wherein the first instructions when executed by the at least one first processor are to:
• receive a notification which indicates that the commander device is to wake up from a hibernation state;
• boot up the commander device in response to receiving the notification;
• and
• transmit a wake-up signal as an energy pulse detectable based on a width and amplitude associated with the energy pulse to a first member device via a first stacking link coupling to the first member device;
• and
• wherein the second instructions when executed by the at least one second processor are to:
• receive the wake-up signal via the stacking link coupling to the first member device;
• boot up a first member device from the hibernation state in response to receiving the energy pulse on the first stacking link;
• and
• transmit the wake-up signal as the energy pulse detectable based on the width and amplitude associated with the energy pulse to a second member device via a second stacking link coupling to the second member device.
