Embodiment
In order to understand the technical scheme that the embodiment of the invention provides better; Down in the face of snmp protocol data cell (Protocol Data Unit; Hereinafter to be referred as PDU) type and SNMP MIB (Management Information Base, management information bank) simply describe.
5 kinds of PDU types have been defined in the snmp protocol, the type of message of corresponding respectively 5 kinds of SNMP operation: Get-Request, Get-Response, Get-Next-Request, Set-Request, Trap.Wherein, The SNMP server is through Get-Request message retrieving information from the network equipment that has the SNMP agency; The SNMP agency then uses the Get-Response message response; Mutual information can comprise: the name of system, the time of normal operation after system's self-starting, the network interface number in the system etc.Get-Next-Request is used for the combine column element of the specific table object of inquiry with Get-Request.Set-Request message (hereinafter to be referred as the Set message) then is used for the network equipment is carried out Remote configuration, can comprise: implementor name is set, device attribute is set, sweep equipment or make some device attributes effectively/invalid etc.The SNMP agency uses Trap to send unsolicited message to the SNMP server, generally is used to describe the generation of a certain incident, like port down, too high, the new user's login of packet loss etc.
SNMP MIB has indicated variable that network element is kept (promptly can by managing process inquiry and the information that is provided with).MIB has provided the data structure of the set of all possible managed object in the network.
In the prior art, the SNMP agency is non-closed loop through the mechanism of Trap message reporting state and problem, and after promptly the SNMP agency sent the Trap message, no matter whether the SNMP server received this Trap message, all can not return response message.Therefore, the SNMP agency can't know whether the Trap message that is sent sends success; When this Trap message sent failure, SNMP agency and SNMP server all can't be known.And since generally speaking SNMP agency's state should be normally, therefore the mode through important state parameter on the SNMP server automatic regular polling SNMP agency can cause waste of network resources, and to SNMP act on behalf of and the influence of SNMP server performance bigger.Simultaneously, the promptness also can't the assurance problem found of this mode.
To the above-mentioned defective that exists in the prior art, the embodiment of the invention provides a kind of technical scheme of Trap message reporting, through in the SNMP agency, special-purpose MIB node being set, is used for confirming the transmission result of Trap message.When the SNMP server received the Trap message that SNMP agency sends, this SNMP server returned the Set message to the SNMP agency, with in the special-purpose MIB node among the SNMP agency variable that should Trap being provided with.SNMP agency confirms that according in the special-purpose MIB node whether variable that should Trap being set up the Trap message sends whether success after sending the Trap message.In embodiments of the present invention, when guaranteeing Trap message reporting reliability, to the influence of SNMP agency and SNMP server performance and all lower to the consumption of Internet resources.
In the technical scheme that the embodiment of the invention provides, the variable that writes down in the special-purpose MIB node can include but not limited to: Trap sign (can uniquely confirm a Trap message through this Trap sign) and SNMP server identification.The information of carrying in the Set message that correspondingly, the SNMP server returns can include but not limited to: Trap sign and SNMP server identification.SNMP agency is provided with variable corresponding in the special-purpose MIB node according to the information of wherein carrying after receiving the Set message that the SNMP server returns.The SNMP agency judges the Trap message according to this special use MIB node, and whether designated SNMP server receives, and can judge that the not designated SNMP server of Trap message carries out handled when receiving.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described in detail.
The embodiment of the invention has proposed a kind of method of Trap message reporting; This method is applied to comprise in the system of SNMP agency and SNMP server; Be provided with special-purpose MIB node among this SNMP agency, the variable that writes down in this MIB node comprises: Trap sign and SNMP server identification.
As shown in Figure 1, the schematic flow sheet of the Trap message reporting method that provides for the embodiment of the invention can may further comprise the steps:
Concrete; When originating port down or packet loss are crossed high fault in the network equipment; The SNMP that is provided with in network equipment agency can report the SNMP server with fault through the Trap message, so that the webmaster personnel are known the fault that this network equipment takes place, and then takes the measure of being correlated with.Wherein, after SNMP agency sends the Trap message, can write down the relevant information of this Trap message, like the sign of the destination server of Trap sign, this Trap message, Trap message transmitting time stamp etc.
Concrete, in order to guarantee the reliability of Trap message reporting, the SNMP server is acted on behalf of message to this SNMP and is returned the Set message after receiving the Trap message of SNMP agency transmission, so that the SNMP agency knows that this Trap message has sent success.
After step 103, SNMP agency receive the Set message of SNMP server response, special-purpose MIB node is provided with according to the Set message that receives.
Concrete, after the SNMP agency receives the Set message that the SNMP server returns, obtain information such as the Trap sign of wherein carrying, SNMP server identification, and special-purpose MIB node is provided with according to the information that gets access to.
Concrete, after the SNMP agency sends the Trap message, in relevant information that can be through the Trap message of self storage relatively and the special-purpose MIB node situation that is provided with of dependent variable is confirmed whether corresponding Trap message sends success.Concrete, the Trap sign and the SNMP server identification that write down in the Trap sign of the Trap message that is sent that the SNMP agency relatively self stores and purpose SNMP server identification and the special-purpose MIB node; In special-purpose MIB node, be provided with the Trap sign of the Trap message that SNMP agency sent, and set SNMP server identification judges that this Trap message is received by corresponding purpose SNMP server when identical with corresponding purpose SNMP server identification; The Trap sign of the Trap message that SNMP agency sends is not set in special-purpose MIB node, or when corresponding purpose SNMP server identification is not set in the special-purpose MIB node, judges that the unappropriated SNMP server of this Trap message receives.
It should be noted that in the technical scheme that the embodiment of the invention provides, can also write down its dependent variables such as timestamp that the SNMP server receives the Trap message in the special-purpose MIB node.Correspondingly, the SNMP server returns in SNMP agency's the Set message and also can carry the timestamp that receives the Trap message.The SNMP server can obtain that this SNMP agency sends the Trap message in a period of time of SNMP proxy records transmitting time is stabbed and special-purpose MIB node in the SNMP server that writes down receive the timestamp of corresponding Trap message, and the situation of current network conditions and/or corresponding SNMP server is analyzed according to the information that gets access to.
Further; In order to improve reliability; After SNMP agency sends the Trap message,, think that then the Trap message that is sent is not successfully sent to this appointment SNMP server if in Preset Time, in the special-purpose MIB node the still unappropriated SNMP server of variable that should the Trap message is provided with.This moment, SNMP agency can send this Trap message to the SNMP server of Trap message of receiving unconfirmed again, in special-purpose MIB node, variable that should the Trap message was set up.
Further,, cause the unlimited re-transmission storm of Trap message for fear of going wrong, in embodiments of the present invention, the maximum number of times of transmission of Trap message can be set in the SNMP agency in advance owing to network to the situation that allows to retransmit the Trap message.The SNMP agency is after the SNMP server sends the Trap message; Write down the transmission number of times of this Trap message; If the maximum number of times of transmission that the transmission number of times of this Trap message equals to preset; And in Preset Time, in the dedicated node variable that should the Trap message is not set up yet, then the SNMP agency confirms to be difficult to accomplish reporting of Trap message for some reason, carries out message and sends failure and handle.
Wherein, this message transmission failure processing can comprise abandons sending this Trap message, and report to the police (as send buzzing and report to the police), trial rebulids with this SNMP server and is connected, and triggering is sent Trap message etc. to subsequent use SNMP server.
In order to promote the efficient of Trap message reporting, and reduce the consumption of Internet resources, in embodiments of the present invention, all can specify in SNMP agency and the SNMP server needs the specific T rap message that responds.On the one hand, when SNMP agency sends the Trap message, can judge whether this Trap message needs response, and when being judged as when being, judge the whether designated SNMP server reception of Trap message according to the information in the special-purpose MIB node.On the other hand, after the SNMP server receives the Trap message, need to judge whether this Trap message of response.Be then to return the Set message if be judged as to the SNMP agency who sends this Trap message; Otherwise, do not respond.For example, can specify the Trap message that reports port down, packet loss to cross high fault is specific T rap message (important Trap message), need respond; And report the Trap message of new user's login, the configuration of newer command row is general T rap message, need not respond.Then receive when reporting port down, packet loss to cross the Trap message of high fault when the SNMP server, return the Set message to the SNMP agency who sends this Trap message; When receiving the Trap message that reports new user's login, the configuration of newer command row, then do not respond.Wherein, in the SNMP server the specified specific T rap message of corresponding same SNMP agency and this SNMP to act on behalf of specified specific T rap message identical
It should be noted that in the technical scheme that the embodiment of the invention provides that for distinct device, the special packet of SNMP server appointment can be different.Promptly to the Trap message (as the Trap message that reports the newer command row to dispose) of same type, can determine whether to specify it according to the equipment that sends the Trap message is specific T rap message.For example, for the Trap message that reports the configuration of newer command row that SNMP agency in the core network device sends, the SNMP server can think that it is specific T rap message (an important Trap message), need respond; And act on behalf of the Trap message that reports the configuration of newer command row that sends for SNMP in common (non-core) network equipment, the SNMP server can think that it is a general T rap message, need not respond.Correspondingly, also need carry the identification information of the network equipment in the Trap message that the SNMP agency sends.
Can find out through above flow process, in embodiments of the present invention,, be used for confirming the transmission result of Trap message through in the SNMP agency, special-purpose MIB node being set.The SNMP agency is after the SNMP server sends the Trap message; Trap according to being provided with in the Trap of the Trap message that it sent sign and purpose SNMP server identification and the said special-purpose MIB node identifies and the SNMP server identification; Judge whether its Trap message that sends is received by corresponding purpose SNMP server; When guaranteeing Trap message reporting reliability, to the influence of SNMP agency and SNMP server performance and all lower to the consumption of Internet resources.
