1. A first network device of a plurality of network devices, comprising:
a network interface having a first Media Access Control (MAC) address;
a first processing resource; and
a first machine-readable storage medium comprising instructions executable by the first processing resource to:
receive a request to wake-up a second network device of the plurality of network devices, the second network device having a second MAC address that is assigned to a same subnet as the first MAC address;
in response to the request, generate a first wake-up frame having the second MAC address as a destination address and configured to cause the second network device to transition from operating in a first power mode to operating in a second power mode; and
transmit, by the network interface of the first network device of the plurality of network devices, the first wake-up frame as an L2 unicast frame to only the second MAC address of the second network device.
