Description
Technical field
The present invention relates to the ethernet technology field, relate in particular to a kind of method and ethernet device that starts ethernet device.
Background technology
In the local area network (LAN) interconnection technique, Ethernet is by U.S. electric and Electronic Engineering Association (Institute ofElectrical and Electronics Engineers, IEEE) a kind of standard of Zhi Dinging.The equipment that is used for Ethernet is the data communications equipment that ethernet device is meant provides one or more ethernet port.Whether have device management software and this device management software is moved necessary management circuit module according to ethernet device inside, ethernet device is divided into management type ethernet device and non-management type ethernet device two classes.Wherein, the management type ethernet device can rely on its inner device management software for the application that the user provides various rich functions and closing to reality, has obtained using more widely in the data communication field.
With the managed switches in the management type ethernet device is example.As shown in Figure 1, managed switches mainly comprises four partial circuit modules: management circuit module 11, Ethernet medium access control system device (Medium Access Controller, MAC) module is that (Physical Layer, PHY) module is Ethernet PHY module 13 and power supply/clock/reseting module 14 that basic operation platform is provided for above each module for ethernet mac module 12, ethernet physical layer.Management circuit module 11 is for device management software provides operation platform, and device management software realizes the management of ethernet mac module 12 is controlled by management interface, and by the indirect management control that realizes Ethernet PHY module 13 of SMI interface.Management circuit module 11 also provides user's configuration interface, and the user can carry out personalized configuration to every function of managed switches by this interface.Ethernet mac module 12 is data processing modules of managed switches, realizes the processing and the forwarding capability of Ethernet message, by managed circuit module 11 controls of management interface.Ethernet PHY module 13 is signal transmitting and receiving modules of managed switches, receives physical layer signal from ethernet port, and converts message data to, by data channel the message data that is converted to is sent to ethernet mac module 12 and handles; Receive the message data that ethernet mac module 12 is transmitted from data channel simultaneously, and convert physical layer signal to, the physical layer signal that is converted to is sent from ethernet port.Power supply/clock/reseting module 14 provides the basic circuit module of power supply, clock and reseting logic for other modules of equipment.
In the Ethernet practical application, cause service disconnection for fear of ethernet device because of port failure, often pass through as redundancy protocol (Redundant), Spanning-Tree Protocol (Spanning Tree Protocol, STP), Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol, VRRP), port trunking multiple redundancy backup agreements such as (Aggregate Port) improves the availability of ethernet device.These redundancy backup agreements are in the network that each ethernet device is formed, for having kept at least two ports simultaneously, some application passages connect link, when wherein primary link breaks down when interrupting, in time switch on the backup link and work, avoid the interruption of Network.When primary link recovers, again from the backup link primary link that automaticallyes switch back.Primary link need to recover the ethernet device on this primary link to recover normally to re-power or reset.When each link connection status changes, will be according to the selected again available link of agreement regulation separately.
In the prior art, the resetting as shown in Figure 2 of ethernet device, reseting module 21 is to management circuit module 22, ethernet mac module 23 and parallel first reset signal, second reset signal and the 3rd reset signal of Ethernet PHY module 24 outputs.After ethernet device powered on, reseting module 21 was carried out a physics homing action to management circuit module 22, ethernet mac module 23 and Ethernet PHY module 24 simultaneously.
Ethernet PHY module 24 is after homing action finishes, and ethernet port can begin to connect (Link up) with other equipment of interconnection immediately, carries out operate as normal, and whole process only needs several milliseconds time.And ethernet mac module 23 need rely on device management software toward contact to transmit rule to being provided with, initial address table or the like initial configuration is provided after homing action finishes, and could carry out the reception and the transmission of Ethernet message afterwards.Finish to the operational outfit management software from management circuit module 22 homing actions, finish the initial configuration of ethernet mac module to realize the reception and the transmission of Ethernet message, tens seconds time of whole process need to device management software again to a few minutes.That is to say that ethernet device is started shooting back tens seconds in the time of a few minutes, ethernet port but can not carry out the reception and the transmission of message to connect only, the malfunction that causes redundancy backup to be used.
With the simplest redundancy protocol is example.As shown in Figure 3, first ethernet device 31 by second ethernet device 32 and three-ethernet equipment 33 set up two each other the link of redundancy backup be linked into other networks.Wherein, the link between first ethernet device 31 and second ethernet device 32 is a primary link, and the link between first ethernet device 31 and the three-ethernet equipment 33 is the redundancy backup link.Suppose operation is restarted in 32 times electricity of second ethernet device or warm start etc.At 32 times electricity of second ethernet device or reseting stage, link (primary link) between first ethernet device 31 and second ethernet device 32 interrupts, first ethernet device 31 switches to link (redundancy backup link) between first ethernet device 31 and the three-ethernet equipment 33 with network path, realizes the no interrupt run of Network.But, to recover normally to re-power or reset when finishing at second ethernet device 32, the Ethernet PHY modules in second ethernet device 32 finish the back at homing action and can rebulid with first ethernet device 31 and be connected.But, will there be tens seconds in the time of a few minutes, the reception and the sending function that can not carry out message of second ethernet device 32 before finishing to initial configuration after setting up connecting because the initial configuration of software startup and ethernet mac module needs.And, because of the link between first ethernet device 31 and second ethernet device 32 is a primary link, priority is higher than the link between first ethernet device 31 and the three-ethernet equipment 33, first ethernet device 31 is got back to primary link detecting immediately network path to be switched after connecting between first ethernet device 31 and second ethernet device 32, causes the interruption of Network.Similarly, other various redundancy backup agreements all inevitably are subjected to the influence that ethernet device connects and but can not carry out the message transmission and receive at the port that starts the existence of initial configuration stage, and mistake occurs.
Therefore, be badly in need of at present a kind of technical scheme and solve ethernet device start back and start initial phase tens seconds ethernet port in the time of a few minutes and but can not carry out the reception and the transmission of message to connect only, and cause the problem of the malfunction that redundancy backup uses.
