Below by introducing embodiment technical scheme of the present invention is further described in detail.Be that example is introduced with application scenarios shown in Figure 1 in the present embodiment, and the IPC link that passes through between two convergence switches connect.Idiographic flow can be that main body is introduced with convergence switch A referring to Fig. 6 here, and the processing procedure of convergence switch B is identical with convergence switch A.And after access switch one powers on, will send load request message, request ply-yarn drill program to the convergence switch of its connection.In addition, when having two convergence switches in network, access switch can send the administrative messag that all is used for system management to two convergence switches, and just the convergence switch as standby main control device can not respond the message that access switch sends.
In step 601, convergence switch A powers on.
Store primary control program and ply-yarn drill program on the convergence switch, these two programs can be stored in after overcompression in the non-volatile carrier of convergence switch, such as Flash.
In step 602, convergence switch A judges whether the IPC link that self is connected with the opposite end can be used, if available, shows to have the opposite end convergence switch, execution in step 603; Otherwise execution in step 604 starts with main control device as main.
In step 603, judge whether the opposite end convergence switch starts with main control device as main, if execution in step 610 starts as standby main control device; Otherwise execution in step 604 starts with main control device as main.
According to step 602～603, convergence switch A just can determine that current master uses main control device.Can recognize that according to this step in the present embodiment, the convergence switch that powers on earlier is the main main control device of using, after the convergence switch that powers on be standby main control device.As for other consult to determine main method with main control device in the prior art,, be not described in detail in this such as priority, weight etc.

In step 608, convergence switch A receives the log-on message that access switch sends in start-up course.The hardware that comprises access switch in the log-on message is formed and the hardware relevant information, just can grasp each building block of access switch by the log-on message convergence switch, and then access switch is effectively managed.
In step 609, convergence switch A judges whether access switch normally starts, if finish current handling process; Otherwise, put the access switch status error, finish current handling process.
In step 610, convergence switch A starts by standby main control device according to primary control program.
In step 611, convergence switch A judges whether the port that links to each other with access switch is available, if available, execution in step 612; Otherwise, there is not access switch to connect, convergence switch A starts end.
In step 612, convergence switch A receives access switch from port and send log-on message start-up course.
After convergence switch starts as standby main control device, can receive the message that access switch sends, but not respond the load request message that access switch sends.
In step 613, convergence switch A judges whether access switch normally starts, if finish current handling process; Otherwise, put the access switch status error, finish current handling process.
Step 612～613 for convergence switch A at the operation of an access switch that available port connected, when convergence switch all executed operation as step 612～613 at each available port after, the start-up course of then current convergence switch A finished.
Through above processing, convergence switch has just become an equipment in logic with access switch.Like this, just can realize this Network Management is comprised two convergence switches and Duo Tai access switch with the convergence switch of main control device as main.
Like this, when carrying out equipment disposition, the configuration of this logical device is just easy.Because loading, the registration process of access switch, cause all hardware that can see all access switch on leading with the order line of main control device to be formed, just can directly directly be configured each access switch on leading with the convergence switch of main control device this moment.Needn't the image set group manage equally, switch on the respective switch and be configured, really realized centralized management at a switch.
In addition, because the start-up routine of access switch all obtains with main control device from main, therefore in software upgrading, only need sign in to as main with on the convergence switch of main control device, will the upgrading software version be saved to and mainly use main control device, a whole then virtual unit to restart to get final product.
Technical scheme of the present invention is except realizing the unified management of a plurality of autonomous devices, when there are two convergence switches in network environment, can also realize the double copies of management plane and Forwarding plane, be that main control device and standby main control device are backups mutually, in case main control device fault, standby main control device are taken over original master and used main control device at once, become the new main main control device of using, eliminate the Single Point of Faliure under the cluster management mode, improved reliability.In addition, with respect to the cluster management mode, be independently on Forwarding plane owing to be in the switch of cluster management, need to prevent that by STP double-layer loop from producing that three layers of forwarding then need VRRP to do load balancing and fault-tolerant processing.Because technical scheme of the present invention has invented an equipment with convergence switch and access switch, it is the same therefore not need the image set group to manage, and operation STP or VRRP agreement realize redundancy.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
