Embodiment
With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.
In this article, the SNMP entity is also referred to as the SNMP node.Each SNMP entity comprises corresponding SNMP engine (Engine).According to the SNMP entity in SNMP effect and the role with its person that is divided into the snmp management and SNMP agency.
The snmp management person, snmp management work station normally, (Management Information Base, MIB) information visits the equipment in the network, perhaps receives the Trap notification message that the SNMP agency initiatively sends to be used for poll SNMP proxy management information bank.The snmp management person has the command request function, can carry out command request GetRequest/SetRequest/GetNextRequest etc. to the SNMP of appointment agency.
SNMP agency, normally various network device comprises router, switch, main frame etc., can send the Trap notification message to predefined snmp management person, and snmp management person's command request is responded (for example, GetResponse).SNMP agency is by obtaining local mib information, snmp management person's command request responded, and perhaps when network equipment generation variety of event, proactive notification snmp management person.
The SNMP engine provides the unit that snmp message transmission and reception etc. are served, and the SNMP engine is corresponding one by one with the SNMP entity.SNMP engine identification (snmpEngineID) generally includes 12 eight-digit binary numbers, preceding four are used to identify Internet and act on behalf of (the Internet Assigned Numbers Authority of member's number management board, IANA) enterprise number of Fen Peiing, for example Acme 696 is exactly ' 000002b8 ' H, eight of backs are normally generated by each enterprise defining, can make the MAC Address of some physical interfaces, be mainly used in unique identification SNMP entity in a management domain
Context engine (Context Engine) is begun to introduce by SNMPv3, is the set of various management information accessed among the SNMP agency, context engine and the identical sign of SNMP engine employing usually.
At first introduce SNMP agency's initialization operation.For example, when dispatching from the factory configuration the corresponding Trap of SNMP agency (for example user residence gateway) configuration is received host address, this address sends the destination address of Trap as follow-up SNMP agency.For example, in SNMPv3, the storage information corresponding in the SNMP agency with following structure:
snmpTargetAddrTable{
snmpTargetAddrName ＝″Manager1″
snmpTargetAddrTDomain ＝snmpUDPDomain
snmpTargetAddrTAddress ＝192.168.1.2/248
snmpTargetAddrTagList ＝″group1″
snmpTargetAddrParams ＝″AuthNoPriv-joe?″
snmpTargetAddrStorageType ＝readOnly(5)
snmpTargetAddrRowStatus ＝active(1)
}
Wherein, the snmpTargetAddrTAddress field is the destination address that the agency sends Trap in the structure, corresponding to snmp management person's address.
Fig. 2 is the flow chart of an embodiment of the management method of the agent equipment based on SNMP of the present invention.
As shown in Figure 2, in step 202, the snmp management person receives the Trap notification message from the SNMP agency.When SNMP agency reaches the standard grade for the first time, will send the Trap notification message, the destination address of setting when this notification message is sent to initialization (for example, snmpTargetAddrTAddress), i.e. snmp management person's address.Generally comprise the information of following structure correspondence in the Trap protocol Data Unit (TrapPDU):
TrapPDU{
transportDomain，
transportAddress，
messageProcessingModel，
contextEngineID，
contextName，
}
Wherein, transportDomain can read by the SNMPTargetAddrTable from previous example, transportAddress reads from SNMPTargetAddrTable, messageProcessingModel is the SNMP version information, context engine sign (contextEngineID) is the contextEngineID of SNMP entity, the title of the corresponding context of contextName.Introduce contextEngineID and be used for identifying the corresponding context engine of each SNMP entity in SNMPv3, this sign adopts snmpEngineID usually.It is unique that snmpEngineID keeps in each management domain, therefore adopts contextEngineID to be used for each management domain SNMP agency of unique identification.
In step 204, the snmp management person obtains SNMP agency's unique identification and IP address from the Trap notification message.Receive SNMP agency's Trap notification message as the snmp management person after, obtain SNMP agency's IP address according to the source IP address of Trap notification message, and obtain SNMP agency's unique identification, for example snmpEngineID on the contextEngineID field from TrapPDU.
In step 206, the snmp management person upgrades SNMP agency's unique identification and IP address.When this SNMP agency reaches the standard grade for the first time, the snmp management person will generate the SNMPAgent object, set up SNMP and act on behalf of corresponding relation between contextEngineID and the IP address, promptly two tuples (contextEngineID, AgentIPAddress).Wherein, contextEngineID is the contextEngineID that reads from TrapPDU, and AgentIPAddress is corresponding SNMP agency's IP address.When the SNMP agency reached the standard grade again, SNMP upgraded two corresponding tuples with unique identification and IP address that the SNMP that obtains acts on behalf of.Therefore, even SNMP agency's IP address changes, because its unique identification contextEngineID does not change, therefore in fact change the sign as the SNMP entity by introducing two tuples in SNMP use IP address, IP address general is only as the SNMP entity address message, and use contextEngineID is as the unique identification information of SNMP entity.For the application scenarios of variable IP address, still can use the SNMP technology to realize Network Management Function like this.
In step 208, the snmp management person carries out the IP address after by SNMP agency's renewal the management for the SNMP agency.With the unique identification information of contextEngineID, when the SNMP agency is managed, this unique identification is converted to the IP address among snmp management person's the MIB by this locality storage binary group information as the SNMP entity.The snmp management person sends command request GetRequest/SetRquest/GetNextRequest etc. to SNMP agency, and the IP address of the SNMP agency in the command request is the IP address after SNMP agency's the renewal.
According to an embodiment of the management method of the agent equipment based on SNMP of the present invention, the snmp management person uses IP address change finger daemon monitoring SNMP Agent IP address change incident.In the local network of users Central Shanxi Plain, usually ADSL goes offline, gateway is started shooting again, the carrier network side forces to take out stitches can cause user residence gateway to dial again distributing new IP address.These incidents all will trigger the Trap notification message.For going up line process the non-first time, with the IP address change finger daemon that triggers among the snmp management person, whether this process will detect two tuples and change, i.e. (contextEngineID, AgentIPAddress), if change the new IP address of corresponding SNMP agency is upgraded, follow-up SNMP will adopt new IP address and agent communication.The snmp management person is by IP address change finger daemon, the variation of monitoring SNMP succedaneum IP address, main monitoring target is the various Trap notification messages that the SNMP succedaneum sends, these Trap notification messages can for example be that link disconnected (linkdown), link connect (Linkup), start (Boot) etc. again, and are not limited to these Trap message above-mentioned.
Fig. 3 is the flow chart of an application examples of the management method of the agent equipment based on SNMP of the present invention.As shown in Figure 3, in step 302, the SNMP agency carries out initialization; In step 304, the SNMP agency sends SNMP Trap notification message; In step 306, the snmp management person registers the agency; In step 308, carry out the SNMP agent address and change renewal.Wherein, preceding two steps are carried out corresponding process processing by the SNMP agency, and latter two steps is carried out respective handling by the snmp management person.By snmp management person and SNMP are acted on behalf of increase alignment processing process in the correlation function, make it to adapt to the applied environment of variable IP address.
The management method of the agent equipment based on SNMP of the present invention, on the basis of existing snmp protocol, make full use of the feature of snmp protocol itself, by introducing (contextEngineID, AgentIPAddress) two tuples are lightened restrictions on SNMP entity and its IP address information, in the applied environment for variable IP address, represent the SNMP entity like this by contextEngineID unique in management domain.By such method, in the SNMP technological frame, solve the problem that SNMP exists, and influencing minimum for what snmp management person and SNMP succedaneum caused, this method of what is more important can not influence basically because the IP address change causes problems such as delay, management for the SNMP entity management is invalid.
Fig. 4 is the structure chart of an embodiment of the manager device based on SNMP of the present invention.As shown in Figure 4, this equipment comprises information acquisition module 41, information updating module 42 and management Executive Module 43.Wherein, information acquisition module 41 is used to receive the Trap notification message from the SNMP agency, the unique identification and the IP address that from the Trap notification message, obtain the SNMP agency, and information updating module 42 is arrived in the unique identification and the IP address that send the SNMP agency.Information updating module 42 is used to store SNMP agency's the unique identification and the corresponding informance of IP address, receives the unique identification and the IP address of self information acquisition module 41, upgrades SNMP agency's the unique identification and the corresponding informance of IP address.Management Executive Module 43 is used for carrying out management to the SNMP agency according to the corresponding informance of the unique identification of the management information bank of manager device and information updating module 42 storages and IP address, the command request that sends to the SNMP agency.
An embodiment according to manager device of the present invention, the information acquisition module reports the contextEngineID field of the Trap protocol Data Unit the announcement information to obtain SNMP agency's unique identification from the Trap from SNMP agency, obtains SNMP agency's IP address from the source IP address from SNMP agency's Trap notification message.SNMP agency's unique identification can be snmpEngineID, and the SNMP agency is user residence gateway.
