Abstract
The present disclosure provides a network switch device and a method of operating the same. The network switch device includes a first port, a second port and a processing device. The first port receives a first clock signal, wherein the first port has a first interface including a first interface number. The second port receives a second clock signal, wherein the second port has a second interface including a second interface number, wherein the first clock signal and the second clock signal have the same quality level. The processing device selects a reference clock signal for synchronization from the first clock signal and the second clock signal based on the first interface number and the second interface number.

A network switch device, comprising:
- a first port configured to receive a first clock signal, wherein the first port has a first interface including a first interface number;
- a second port configured to receive a second clock signal, wherein the second port has a second interface including a second interface number, wherein the first clock signal and the second clock signal have the same quality level;
- and
- a processing device configured to select a reference clock signal for synchronization from the first clock signal and the second clock signal based on the first interface number and the second interface number.
A network switch device, comprising:
- a first port configured to receive a first clock signal, wherein the first port has a first port number;
- a second port configured to receive a second clock signal, wherein the second port has a second port number, wherein the first clock signal and the second clock signal have the same quality level;
- and
- a processing device configured to select a reference clock signal for synchronization from the first clock signal and the second clock signal based on the first port number and the second port number.
A method of operating a network switch device, comprising the steps of:
- receiving a first clock signal at a first port of the network switch device, the first port having a first interface including a first interface number;
- receiving a second clock signal at a second port of the network switch device, the second port having a second interface including a second interface number, wherein the first clock signal and the second clock signal have the same quality level;
- and
- selecting a reference clock signal for synchronization, based on the first interface number and the second interface number, from the first clock signal and the second clock signal.
