Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that: when the above-mentioned configuration method fails in self-negotiation, the network devices at both ends need to be reconfigured; All devices know the master-slave state configuration information that should be set, which increases the complexity and overhead of master-slave network device configuration
In addition, in the normal communication process, when the current master-slave state configuration information of one end of the network device changes, the above configuration method will cause the master-slave network device switchover to fail; for example, for network device A and network device B, the current state of network device A The master-slave state configuration information is manual-Master, and the current master-slave state configuration information of network device B is manual-Slave. When the current master-slave state configuration information of network device B changes from manual-Slave to manual-Master, network device A The current master-slave status configuration information is still manual-Master. Therefore, the physical layer auto-negotiation fails, the ports of the network devices at both ends are in the down state, and the master-slave network device switchover fails.
It can be seen that the above-mentioned master-slave network device configuration method affects the maintainability of network devices

Embodiment 1

[0021] Embodiment 1. A master-slave network device configuration method. The flow of the method is attached figure 1 shown.

[0022] figure 1 In S100, the network device receives master-slave state configuration information.

[0023] The network device here may be a network device supporting synchronous Ethernet, for example, the network device may be a network device including a 1000BASE-T PHY chip. The master-slave state configuration information may indicate that the network device is set as manual-Master or manual-Slave.

[0024] S110. The network device performs physical layer auto-negotiation with the peer network device according to the received master-slave state configuration information, and sets the master-slave state configuration mode of the network device to an automatic mode.

[0025] In the prior art, if the master-slave state configuration mode is set to automatic mode, the network devices at both ends will perform physical layer auto-negotiation for the a...

Embodiment 2

[0044] Embodiment 2, a master-slave network device configuration method. The flow of the method is attached figure 2 shown.

[0045] figure 2 In S200, the network device receives master-slave state configuration information. The master-slave state configuration information may be manual-Master or manual-Slave. The network device may be a network device supporting synchronous Ethernet.

[0046] S210, the network device judges whether the current port state and the received master-slave state configuration information are the same as the current master-slave state configuration information. If the network device judges that the current port status is up and the received master-slave configuration information is the same as the current master-slave configuration information, go to S230; otherwise, go to S220.

[0047] S220. The network device performs physical layer auto-negotiation with the peer network device according to the received master-slave state configuration inf...

Embodiment 3

[0050] Embodiment 3, a master-slave network device configuration method. The flow of the method is attached image 3 shown.

[0051] image 3 , S300. Before the network device 1 and the network device 2 communicate normally, both the network device 1 and the network device 2 perform master-slave configuration, and both the network device 1 and the network device 2 receive the master-slave configuration information. It can be understood that at this time, the network device 1 and the network device 2 are powered on and started, and the current port states of the network device 1 and the network device 2 are both down. to S310.

[0052] S310. After receiving the master-slave status configuration information, network device 1 and network device 2 both detect that the current port status is down, then the first physical layer auto-negotiation is performed between network device 1 and network device 2, and the network device Both 1 and network device 2 will set their master-sla...

Abstract

The invention discloses a technical proposal for a method for configuring master-slave network equipment, a device and a system thereof, wherein, the method comprises the following steps: the network equipment receives configuration information of master-slave state; the network equipment carries out physical layer auto-negotiation according to the received configuration information of the master-slave state; setting the configuration mode of the master-slave state of the network equipment as an automatic mode; and cancelling the physical layer auto-negotiation aiming at the setting of the current automatic mode. The technical proposal can avoid the phenomenon that network equipment at two ends needs to carry out the configuration process and the interaction process of the upper layer of information again when the physical layer auto-negotiation is fault and the switching of the master-slave equipment is fault and improves the maintainability of the network equipment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a master-slave network device configuration method, a master-slave network device configuration device and a system. Background technique [0002] In a network device using a Master-Slave (master-slave) mechanism, the Master network device uses a local clock to send data, and the Slave network device uses a recovered clock to send data. [0003] The existing master-slave network device configuration method is: according to the network clock state (such as the Ethernet synchronization state information ESSM level), the master-slave state configuration information of the network devices at both ends is set, and then the network devices at both ends carry out PHY (physical) layer auto-negotiation , if the master-slave status configuration information of the network devices at both ends is set to manual-Master (manual configuration-master) or manual-Slave (manual config...
