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 the more comprehensive scheme of common loopback detection 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 member port this message just explains that this aggregated links produces loop, the member port that just can confirm 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.Describe below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is the loopback detection processing method implementing procedure sketch map of aggregated links, and is as shown in the figure, when loopback detection, can comprise the steps:
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:
Confirm 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 ease, 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 sketch map, and is as shown in Figure 2, the aggregated links of being made up of 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.That is, 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 explains that this aggregated links has formed loop.
