Method, apparatus and system for configuring master-salve network device

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...

AI Technical Summary

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
