The third embodiment:
as shown in fig. 4, a communication method of a network device according to an embodiment of the present invention includes:
step 41: acquiring master/standby state information of at least two master control units;
the communication method of the network equipment of the embodiment of the invention can be realized based on the following architecture: a CPU processing unit; a timing query unit; an ethernet L3 switching unit; a protection decision unit; ethernet L2 switching unit.
The CPU processing unit processes network management messages of the network management system and the device, can process various management messages of the network management, and is responsible for initializing the ethernet L3 switching unit and the ethernet L2 switching unit after the device is powered on.
The ethernet L3 switching unit is responsible for forwarding the network management message, can identify whether the network management message is a message of the device or other network element devices, can upload the local network management message to the CPU processing unit, and forwards the network management message of the non-accessed network element to other network elements according to the routing information of the network.
The timing query unit is mainly used for regularly querying the port state of the current main control unit and whether the current main control unit is the main control unit or the standby main control unit, wherein the port state is mainly obtained from the port detection unit and information is transmitted to the protection decision unit.
The protection decision unit regularly acquires the current master/standby state and the link establishment state of the network management port from the query unit, and decides the forwarding domain and the forwarding state of the current Ethernet L2 switching unit according to the queried information, and the rule is as follows:
1. ensuring that the currently used network management link message can be sent to the current master Ethernet L2 switching unit;
2. currently, the main master control can only select one link from the network pipe orifice of the local board and the network pipe orifice of the back board to send the network management message to the Ethernet L3 switching unit, and if the management orifice on the main master control is in an up state for the sending direction, the management orifice is preferred;
3. the messages of the management link of the standby master control cannot be sent to the ethernet L3 switching unit of the standby master control, and when the management port of the active master control is in the up state, it needs to be ensured that the messages of the management port can be sent to the active master control.
The Ethernet L2 switching unit configures the switching domain of the unit according to the configuration information of the protection decision unit.
Specifically, after the device is powered on, the ethernet L3 switching unit and the ethernet L2 switching unit are initialized to enable the switching units to work normally, a timer is started, and the protection decision unit acquires the master/standby state information through the timing query unit.
Step 42: and detecting one main control unit and at least one standby main control unit in the at least two main control units according to the main/standby state information, and taking the main control unit as the current main control unit.
Specifically, the protection decision unit determines whether the current board is the primary main control or the standby main control according to the primary and standby information reported by the timing query unit.

Specifically, if the current board is the master control, and the state information of the current on-board network management port reported by the timing query unit is down, the P2 port and the P3 port of the current master control unit need to be set to the same two-layer forwarding domain a, and at this time, the network management link channel refers to fig. 5; if the management port of the current master control unit is in the up state, the P1 port and the P2 port of the current master control unit are added into the two-layer forwarding domain a, meanwhile, the P3 port is removed from the two-layer forwarding domain a, and the mac forwarding table is aged, and at this time, the network management link channel refers to fig. 6.
If the current master control board is a standby master control, the protection decision unit removes the P2 port of the Ethernet L2 switching unit from the two-layer forwarding domain A, sets the P1 port and the P3 port to be the same forwarding domain A, and ages the forwarding table of the Ethernet L2 switching unit to ensure that only one management link works.
Further, if it is monitored that the master/standby state information changes, the master/standby state information of at least two master control units is obtained again;
and according to the re-acquired main and standby state information, re-detecting one main control unit and at least one standby main control unit in the at least two main control units, and taking the re-detected main control unit as the current main control unit.
In a specific embodiment of the present invention, when the active/standby state information of the main control unit changes, the active main control unit is detected again, and the network device is controlled to communicate with the network device through the CPU of the current active main control unit. In the embodiment of the invention, when the main and standby main control boards are switched, the link state can be switched in time, and the normal device management channel is ensured. Specifically, referring to fig. 7, it shows all flow directions of the network management message in the embodiment of the present invention, where the flow directions of the management message when the main and standby main control boards are switched are included, and it is assumed that the left main control unit in fig. 7 is the main master, and the right main control unit is the standby master, at this time, the CPU processing unit of the main master communicates with the network device, if the main-standby relationship of the main control units changes, that is, the left main control unit becomes the standby master, and the right main control unit becomes the main master, at this time, the CPU of the right main control unit communicates with the network device.

If the current single board is the main master control, turning to the step two; if the master control is the standby master control, the step three is carried out.
Step two: under the condition that the current master control is the main master control and the query module normally operates, if the port of the port P1 is in a down state, the port P2 and the port P3 need to be set to be the same two-layer forwarding domain vlan4094, if the current management port is in an up state, the port P1 and the port P2 are added into the two-layer forwarding domain vlan4094, meanwhile, the port P3 is removed from the two-layer forwarding domain vlan4094, and meanwhile, the mac forwarding table is aged.
Step three: if the current master is the standby master, the port P2 is removed from the two-layer forwarding domain vlan4094, and the port P1 and the port P3 are set to the same forwarding domain vlan4094, while the mac forwarding table is aged out.
Step four: when the state of the network management port of the board is inquired to be changed by the timing inquiry module, the protection decision unit is required to be sent upwards, the protection decision unit judges whether the current board is a main master control or a standby master control again, and if the current board is the main master control, the step II is switched to; if the master control is the standby master control, the step three is carried out.
Step five: when the current query module queries that the main/standby state of the current single board changes, the current information needs to be uploaded to a protection decision unit, the protection decision unit judges whether the current single board is a main master control or a standby master control again, and if the current single board is the main master control, the step II is switched to; if the master control is the standby master control, the step three is carried out.
