Abstract: In some implementations, a device may receive, via a universal serial bus (USB) interface, configuration information and a supply of power from a network device. The device may receive, via an antenna that is external to the device, a first signal indicating timing information. The device may generate, based on the first signal, a second signal and a third signal, wherein the second signal comprises a one pulse per second signal and the third signal comprises a ten-megahertz signal. The device may provide, to the network device, the second signal and the third signal. The device may receive, via an input port, a clock signal to provide an extended holdover functionality to the network device.

Abstract: A network device may identify a link aggregation group (LAG) of a plurality of links between the network device and another network device. The network device may identify link aggregation control protocol (LACP) parameters that were communicated by the network device and the other network device in association with the LAG. The network device may determine, based on the LACP parameters, a priority order of the plurality of links in the LAG. The network device may communicate with the other network device, and based on the priority order of the plurality of links of the LAG, one or more precision time protocol (PTP) messages via the LAG. For example, the network device may determine that a first link and a second link in the priority order are not available, and therefore may communicate the one or more PTP messages via a third link in the priority order.
