Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is retouched in detail
It states.
In general, an equipment includes multiple ports (port), it is the outlet of equipment and extraneous Communication.Port can be divided into
Virtual port and physical port.Wherein, virtual port can be logic port；Physical port is different from virtual port, can be
Hardware interface in equipment.Equipment in the embodiment of the present invention can be the equipment that router, interchanger etc. support LACP agreement.
With reference to Fig. 1, the state of port is defined in LACP agreement, can specifically include following several states:
1, current (opening) state
The port of equipment enters current state after receiving the LACP message that opposite end is sent.Wherein, LACP message, that is, LACP
Protocol massages.In general, message can be divided into data message and protocol massages, protocol massages are for transmitting various Routing Protocols；Number
It is the flow that user uses various applications according to message.
2, EXPIRED (failure) state
If the port of equipment does not receive opposite end transmission in current_while_timer (message keep-alive) in the time
LACP message, port status then by current state transition to EXPIRED state, are set to not after overtime with opposite end synchronous regime
It is synchronous.
3, DEFAULTED (default) state
If the port of equipment is reported after current_while_timer time-out still without the LACP for receiving opposite end transmission
Text, port status is then by EXPIRED state transition to DEFAULTED state.
4, INITIALIZE (initial) state
If equipment checks port exception, such as: the physical connection of port changes, and port then enters INITIALIZE
(initial) state.Meanwhile that sets port selects state (not to be selected) state for UNSELECTED, in this way this port will by from
It is deleted in aggregation group.Certainly, when port normal transmission message, port selects state for SELECTED state.
In LACP agreement, equipment can be by multiple trunkings to an aggregation group, in general, there is a port in aggregation group
In SELECTED state (i.e. selected state), which is known as master port (Master Port), master port logically generation
The entire aggregation group of table.Some protocol massages, such as: the protocol massages of GVRP/GMRP, STP/RSTP/MSTP two-layer protocol, all
Only sent from master port.
One can be connected between equipment and adjacent equipment by physical port, establish communication link, can also pass through void
Communication link is established in quasi- port.Specifically, equipment can be one priority of each port assignment, usually by highest priority
Port is configured to selected state, remaining port is configured to unselected state, and further, equipment 1, equipment 2 utilize selected state
Port is held consultation, and communication link is established.Negotiations process specifically includes: equipment 1 is sent out by the port of selected state to equipment 2
Protocol massages are sent, which chooses the information of port (the as port of selected state).Equipment 2 receives
A protocol massages are replied to equipment 1 after this message, which chooses the information of port, equipment 1 to choose
The information of port.Equipment 1 receive equipment 2 transmission protocol massages after to equipment 2 reply confirmation message (such as: ACK), just complete
Entire negotiations process.
In general, can establish multiple communication links between two equipment, the different data of different communication links.One
A link can be there are two transmission direction.Exemplary, with reference to Fig. 2, two ports in equipment 1 are docked with equipment 2 respectively, including
Link 1, link 2.By taking link 1 as an example, two transmission directions include from equipment 1 to 2 direction of equipment and from equipment 2 to equipment 1
Direction.So-called single-channel fault refers to that certain link between two equipment breaks down, and can only realize from an equipment to another
The data transmission of one equipment can not achieve two-way data transmission.By taking two equipment shown in Fig. 2 as an example, Fig. 3 shows one
The scene of kind single-channel fault, the data of 1 single-channel fault of link, i.e. equipment 1 to 2 direction of equipment, which are transmitted, to break down, and equipment 2 receives
The data sent less than equipment 1.The data transmission in equipment 2 to 1 direction of equipment is normal, and equipment 1 can receive the transmission of equipment 2
Data.The single-channel fault that link 1 occurs is also possible to equipment 1 to be transmitted normally to the data in 2 direction of equipment, and equipment 2 can receive
The data sent to equipment 1.The data in equipment 2 to 1 direction of equipment, which are transmitted, to break down, and equipment 1 does not receive the transmission of equipment 2
Data.
According to LACP consensus standard, after the port of certain equipment receives message time-out, which can send initial association to opposite end
Business's text, the initial negotiation message middle port information are reset, i.e., do not include any port information in initial negotiation message, and should
The port status of the port can be labeled as INITIALIZE state by equipment.In this way, when there is single-channel fault shown in Fig. 3,
Equipment 2 does not receive the message of the transmission of equipment 1 within the specific time, then sends initial negotiation message to equipment 1.It needs to illustrate
, so-called " specific time " can be the message keep-alive time, such as: above-mentioned current_while_timer.When message keep-alive
Between starting point can be 2 last time of equipment receive equipment 1 transmission message at the time of.In general, message keep-alive time and message
Sending cycle is exemplary at multiple proportion, it is assumed that message sending cycle 1s, keep-alive multiple are 3, then the message keep-alive time is exactly
3s.If equipment 2 does not all receive the report of the transmission of equipment 1 in the 3s after the upper message for once receiving the transmission of the first equipment
Text will send out Initial message to equipment 1.
Further, since the data transmission of equipment 2 to 1 direction of equipment is normal, equipment can receive the hair of equipment 2
The initial negotiation message sent.In addition, it is selected state that equipment 1, which still keeps the corresponding port of link 1,.In this way, although equipment 1 receives
It can determine that single-channel fault has occurred in link 1 after the initial negotiation message, but equipment 1 will not do other processing, so just lead
It causes equipment 1 to pass through the loss of data that link 1 is sent, and then influences the data between equipment 1 and equipment 2 and transmit.
The principle of the application is: other port is chosen when single-channel fault occurs, and based on the port chosen again
It establishes new link, carries out link switching, it is enterprising that the data transmission of equipment room from current chain road is switched to new link
Row, in this way, carrying out data transmission two equipment on the link, is not influenced by single-channel fault.It is exemplary, reference
Single-channel fault occurs for Fig. 4, link 1, and equipment 2 does not receive equipment 1 and passes through the data message that link 1 is sent, and equipment 1 can be by chain
The corresponding port in road 2 is set as selected state, is carried out data transmission by link 2 and equipment 2.

Part perhaps combines certain components or different component layouts.
The embodiment of the present application provides a kind of fault handling method, as shown in fig. 6, method includes the following steps:
101, the first equipment sends the first message by the second equipment described in the first chain road direction between the second equipment.
In the specific implementation, the first equipment carries out port negotiation firstly the need of with the second equipment, according to the first equipment, second
Above-mentioned first link is established in the port of equipment, exemplary, establishes the first port of the first equipment and the third port of the second equipment
Between link, which is the first link described in the embodiment of the present invention.In addition, first port, third port can claim
For the corresponding port of the first link.Certainly, first port, third port port status be that selected state is (i.e. above-mentioned
SELECTED state).Further, first port, third port can be a virtual port of the first equipment, the second equipment,
It is also possible to a physical port of the first equipment, the second equipment.
That is, the first link is the first equipment and the negotiated successful communication link of the second equipment, first
Equipment can be sent datagram by first the second equipment of chain road direction.In addition, the first message can be data message, that is, it is used for
Transmit the message of user traffic data.
It should be noted that if the third port (the corresponding port of the first link) of the link aggregation group of the second equipment is sent out
It is born from ring or other failures, and the first equipment cannot perceive the variation of third port state in time, the first equipment can still pass through
One link (passing through first port) sends message to the second equipment, and the data traffic that so will cause the first chain road is lost.
102, the second equipment sends response message by first the first equipment of chain road direction.
It should be noted that the response message in the embodiment of the present invention refers in particular to initial negotiation message, the second equipment of instruction is not
Receive the data message of the first equipment transmission.
In general, if the port (i.e. the corresponding third port of the first link) of state is selected to go out in the aggregation group of the second equipment
The data traffic of existing failure, the first chain road is lost, then the third port that will lead to the second equipment receives message time-out, that is, is being reported
The message of the first equipment transmission is not received in the literary keep-alive time.
Further, after the second equipment receives message time-out, initial negotiation message will be sent to the first equipment.Specifically,
Second equipment last time was moment A at the time of receiving the message that the first equipment is sent, within the message keep-alive time after moment A
The message of the first equipment transmission is not received yet, and the second equipment then sends initial negotiation message, the initial negotiation to the first equipment
Any port information is not included in message, and the port status of third port can be set to INITIALIZE shape by the second equipment
State.In this way, the first equipment, which can perceive the first link after receiving the initial negotiation message, there is failure.
It should be noted that the above-mentioned message keep-alive time is the integral multiple of message sending cycle.Sending the message period can be with
It is short cycle, is also possible to long period.Wherein, short cycle and macrocyclic specific time provide to determine according to agreement, for example, existing
Having agreement (802.1ax) short cycle is 1 second, and long period is 30 seconds.The message keep-alive time can be the 3 of message sending cycle
Times.For example, it is configured to fast (i.e. short cycle), the message keep-alive time is 3 seconds；It is configured to slow (i.e. long period), message
The keep-alive time is 90 seconds.
That is, if the second equipment is not received by the data message (such as: the first message) of the first equipment transmission,
Initial negotiation message is sent to the first equipment, in some embodiments, the second equipment is after sending initial negotiation message for the first time, also
It can continue to send initial negotiation message to the first equipment.Such as: the second equipment can be spaced after preset duration sends initial association again
Business's text, preset duration can be 10s.
Certainly, if the second equipment has received the data message (such as: the first message) of the first equipment transmission, show first
Link is normal to the direction of the second equipment from the first equipment, and the second equipment then sends datagram (such as: the present invention to the first equipment
Third message described in embodiment), with the first equipment interaction data.
In some embodiments, the initial negotiation message that the second equipment is sent can be identified with carrier state, the state mark
Know the data message that the second equipment of instruction does not receive the transmission of the first equipment.
103, the first equipment receives above-mentioned response message, determines that the second equipment does not receive first and sets according to the response message
The first message that preparation is sent.
Specifically, the first equipment receives the initial negotiation report that the second equipment is sent by the first link at the first moment
Text.Then, the first equipment carries out the packet check of preset duration after first moment, and what determination received is strictly just
Beginning negotiation packet.Further, if second moment of first equipment after completing packet check still receives the second equipment hair
The initial negotiation message sent, it is determined that the second equipment does not receive the data message that the first equipment is sent in step 101.Example
, after the first equipment receives the initial negotiation message of the second equipment transmission, 10s is detected, still receives initial negotiation report after 10s
Text, it is determined that the second equipment does not receive the data message that the first equipment is sent in step 101.
Alternatively, carrying the second equipment of instruction in the initial negotiation message that the second equipment is sent does not receive the transmission of the first equipment
Data status indicator, the first equipment receives initial negotiation message, parses the initial negotiation message and identify state mark therein
Know, and then can determine that the second equipment does not receive the data message that the first equipment is sent in step 101.
