The SNMP Network Management Station is to its member's management method
Technical field
The present invention relates to the management method of a kind of SNMP (Simple Network Management Protocol) Network Management Station to its member.
Background technology
Simple Network Management Protocol SNMP is the cover NMP by the Internet engineering duty group IETF (Internet Engineering Task Force) definition.This agreement has become the actual industrial standard of network management aspect at present, has obtained accepting widely and using.
SNMP has adopted the special shape of Client/Server model: agency/management station's model.To Network Management and maintenance is to finish by the interworking between SNMP network management management station and SNMP agency.Each agency is responsible for answering various inquiries or the operation of management station about MIB (Management Information Base) definition information.The SNMP Network Management Station is the software systems of being used by the keeper, and main being responsible for sends network management command or request to the agency, generally is positioned at server end, and has good user interface, is user-friendly to.The agency is a software module that is positioned on member's network equipment, it is the part of network equipment side software system, main be responsible for the SNMP request that the receiving management station sends over, and link up with other software module on the network equipment, alternately, finish desired inquiry of management station or operation.Generally have the relation of one-to-many between management station and the agency, the keeper manages a plurality of network equipments by a management station.MIB is equivalent to the tabulation of management information or object, or perhaps a agreement between management station and the agency, and both sides link up as standard.Each agency may support one or more MIB, and these MIB have constituted the management information that this agency can support or the set of object.These MIB that management station is also supported according to the agency just visit and control and management information or object.
As previously mentioned, management station belongs to two different software systems with the agency, and is that standard is communicated with each other again with MIB between them.Like this,, will upgrade simultaneously to management station and agency's software if the extended network management function needs to upgrade MIB.It is quite complicated that but this problem will become in reality, especially for the agency.Because the agency is a part that belongs to network equipment side software system, together sell in company with the network equipment.At first, the quantity of the network equipment usually can be many, and the workload of software upgrading will be very big; Secondly, the operating network equipment is carrying the traffic, does not generally allow to interrupt, and especially the network equipment of those cores is all the more so, and this will make the software upgrading of member's network equipment become possible hardly.
Simultaneously, generally speaking, the user is not the whole network equipment of disposable purchase yet, but according to demand and the development, buy in batches one by one.Like this, the back network equipment the MIB version possibly than the height of front, will have the different network equipment of a plurality of new and old editions.And the agency of the SNMP in these network equipments has also just become the MIB that supports a plurality of new and old editions.This has just caused in many versions environment, the coordination problem of MIB version between management station and the agency.If this problem can not be properly settled, will seriously influence MIB, management station and the agency's of SNMP renewal upgrading, also will seriously restrict the development and the application of SNMP network management technology.
Summary of the invention
To existing problem and shortage in its member's network device management, the purpose of this invention is to provide the management method of a kind of simple to operate, SNMP Network Management Station that function is good at above-mentioned existing network management station to its member.
The present invention is achieved in that the management method of a kind of SNMP Network Management Station to its member, may further comprise the steps,
1), version sign is set for the MIB among described member's the agency;
2), before SNMP network management website access member device wishes to get its mib information,, inquire about the version sign of this member device agency's MIB, obtain the corresponding version number of this MIB according to this MIB title;
3), the SNMP Network Management Station is carried out corresponding bookkeeping according to the version number of the MIB of agency's support of described member device.
Further, the version sign of described MIB is the part of this MIB.
The present invention is by for the MIB among the agency of member device is provided with version number, in order to identify this MIB; Like this, the SNMP Network Management Station is at first inquired about the version identifier of MIB among the agency of this member device, obtains its corresponding version number, and the version number according to MIB carries out corresponding bookkeeping again.The present invention has solved some problems of MIB, management station and the agent update upgrading of restriction SNMP up hill and dale, has promoted the development and the application of SNMP network management technology effectively.And,,, can not influence management station yet it is conducted interviews even its MIB version number is different with other any equipment if new member device need be inserted by system.And, only management station is carried out corresponding upgrading and just can manage this new equipment.The present invention does not rely on other outer supplementary means of SNMP.
Description of drawings
Below in conjunction with accompanying drawing, the present invention is made detailed description.
Fig. 1 is a flow chart of the present invention.
Embodiment
If the MIB among the agency contains AAA-MIB,,, then this version number is identified in AAA-MIB if current version is 1.0 for AAA-MIB adds the aaaMibVersion object.If need be upgraded to 1.1, as increase the new B that acts on behalf of, but require the A that acts on behalf of of existing support AAA-MIB 1.0 still can operate as normal.Like this, new act on behalf of B and make modification according to AAA-MIB 1.1 after, revising aaaMibVersion is 1.1.Subsequently the software of management station is also upgraded.At this moment, management station just can be according to the value of aaaMibVersion, and the version of distinguishing the AAA-MIB that acts on behalf of the A support is 1.0, is through upgrading; And the version of acting on behalf of the AAA-MIB of B support is 1.1, is through upgrading.
As shown in Figure 1, SNMP network management website access member's of the present invention concrete steps are, the version of the sign MIB that inquiry proxy is supported of the MIB of agency by the member, the agency feeds back to the SNMP Network Management Station with the version situation of its MIB that supports, the SNMP Network Management Station is called the software at the version of MIB, send corresponding querying command, the agency carries out this order, and response results is fed back to the SNMP Network Management Station.
