Embodiment
In order to carry out effective loopback detection, will provide a kind of in the technical scheme that the embodiment of the invention provides than common loopback detection scheme more fully to aggregated links.In the scheme, when the loopback detection of aggregated links begins, can generate a kind of loopback detection message of unique this aggregated links of expression, each member port from aggregated links sends successively, in message, insert the PORT ID (port-mark) of corresponding port during transmission, if receive that at any one member port this message just illustrates that this aggregated links produces loop, the member port that just can determine the formation loop that aggregated links is concrete according to the port PO RT ID of the PORT ID of the port in the message content and reception message with become the lopps type.Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
Fig. 1 is the loopback detection processing method implementing procedure schematic diagram of aggregated links, as shown in the figure, can comprise the steps: when loopback detection
During this step is implemented, when the sign according to the sign of the aggregated links in the first loopback detection message and the second loopback detection message and member port determines whether to form loop, can comprise: if identical then this aggregated links of the sign of aggregated links forms loop, otherwise this aggregated links does not form loop, if this member port of identical then this aggregated links of sign of the sign of aggregated links and member port forms loop, otherwise this member port of this aggregated links does not form loop.
Further, can also comprise in force:
Determine the number and the sign thereof of the member port of the reception second loopback detection message;
If this member port forms loop, the type that is specified to ring according to the number and the sign thereof of the sign of the member port of the transmission second loopback detection message that carries in the second loopback detection message and the member port that receives the second loopback detection message.
In step 101 is implemented, can carry out the setting of loopback detection earlier to concrete aggregated links, generate a kind of identification code of unique this aggregated links of expression, this identification code comprises the TRUNK ID of aggregated links in the sequence number of unique this data equipment of expression, user-defined words identification and this data equipment of unique expression.The sequence number of data equipment can be obtained by device hardware; The user can import one section self-defined words identification, can prevent the malicious attack to data equipment to a certain extent; TRUNK ID will generate having disposed aggregated links.
In the enforcement, the purpose of selecting the sign of this aggregated links corresponding device for use is for convenience, also is convenient to identify this aggregated links simultaneously and belongs to which equipment.In fact,, adopt other identification means also can implement, behind the identification code that generates this unique this aggregated links of expression, just can in the first loopback detection message, carry this identification code as long as identification code can guarantee that only table illustrates an aggregated links.
Confirm the PORT ID of its all member ports according to the aggregated links that has disposed loopback detection, Fig. 2 is the aggregated links schematic diagram, as shown in Figure 2, and the aggregated links of forming by five member ports; Successively identification code is added the loopback detection message content of the PORT ID of member port as each member port.Each member port has just generated loopback detection message separately like this, can send from port separately.
In step 102,103 enforcement, on all member ports, intercept the data message that receives, if in the time limit of setting, receive data message, just need the analytic message content to come to compare with the loopback detection message that sends.Promptly, the first loopback detection message and the second loopback detection message are compared, confirm at first whether destination address is identical with the message that sends out with source address, if it is identical, just with the sequence number of data equipment, user-defined sign and TRUNK ID compare, no matter message from which member port is received, if below all identically just think that this message is the loopback detection message that this aggregated links sends, and illustrates that this aggregated links has formed loop.
In concrete the enforcement, when the sign according to the sign of the aggregated links in the first loopback detection message and the second loopback detection message and member port determines whether to form loop, can comprise:
Whether the sign identification code whether identical, aggregated links that compares the aggregated links corresponding device successively is identical, whether the sign of the member port of aggregated links is identical;
After determining that according to comparative result aggregated links forms loop, whether this member port of determining this aggregated links forms loop, after determining that according to comparative result aggregated links does not form loop, after this member who determines this aggregated links forms loop, further be specified to the type of ring; Stop to determine whether to form loop.
Below carry out more in order, have different item just to think that aggregated links does not form loop, its role is to reduce the utilization rate of CPU as long as find.
In the enforcement, if confirm to have formed loop, just read the PORT ID in the data message that listens to, and compare, so just can confirm the member port of concrete formation loop and the loop type of formation with the PORTID of the port that receives this loopback detection message.Be exemplified below:
(1), Fig. 3 is that the single Member Link of aggregated links forms the loop schematic diagram, if in the setting time limit, have only a port to receive the loopback detection message of this aggregated links, and the PORTID in the message content equates with the PORTID of the port that receives this message, then form single Member Link loop, as shown in the figure, expression member port one receives that the loopback detection message that oneself sends forms single Member Link loop.
(2), Fig. 4 is that aggregated links two member's links form the loop schematic diagram, if in the setting time limit, have only a port to receive the loopback detection message of this aggregated links, but the PORT ID in the message content is unequal with the PORTID of the port that receives this message, then forms two member's link loops; As shown in the figure, expression member port 4 receives that the loopback detection message that port one sends forms two member's link loops.
(3), Fig. 5 is that the many Member Links of aggregated links form the loop schematic diagram, if having a plurality of ports to receive the loopback detection message of this aggregated links setting in the time limit, then forms many Member Links loop; As shown in the figure, represent that a plurality of member ports (can be in all member ports a plurality of arbitrarily) receive that the loopback detection message that port one sends forms many Member Links loop.
PORT ID in the data message that listens to is carried out one by one the processing of above (1), (2), (3).
After confirming to form loop, just need handle loop.Therefore can further include:
After confirming to form loop, close the member port that forms loop;
Send the loop warning information.
In the enforcement, can close the member port that forms loop, and send the loop warning information, can show aggregated links that forms loop and the member port that forms loop thereof in the warning information and become the lopps type to the user.Because the redundancy backup function of aggregated links can not cause the business datum communication interruption of this aggregated links, but need notify the user to handle as early as possible.
