Embodiment
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
In cluster management protocol,, finish management to an Ethernet switch set by only using the IP address of a public network.Specifying a switch earlier is command switch, and public network address of configuration manages its member switch on command switch.Command switch can link to each other with many member switch.Command switch with the member switch exchange message, is collected topological corresponding message by its collecting topology protocol module, and the network topological information in the arrangement message is finished network topology and collected.
The present invention uses an IP address in order to support in the cluster management, the advantage that makes full use of the snmp protocol way to manage reaches the purpose that large-scale Ethernet switch is managed.As shown in Figure 1, the present invention distributes the IP address 100.1.1.2 of a public network according to the topological structure of cluster management to command switch A; And to cluster in command switch have each member switch of topological connection relation all to distribute the SNMP port numbers of a mapping, from 19501-19505; Described command switch is SNMPManager Station (management station), and described member switch is SNMP Agent (agency), and the SNMP port numbers of described mapping is UDP (User Datagram Protoco (UDP)) port numbers of SNMP factorage; Have a message to transmit processing module on command switch, it receives the SNMP message, and the message that the requesting party is sent is transmitted to member switch B or the member switch C or the member switch E that will visit, or the like; Command switch will reply to the requesting party from the answer message that member switch is received again then, thereby, realized cluster management method based on snmp protocol.
In order to realize above-mentioned cluster management method based on snmp protocol, the requesting party need send to the SNMP message command switch of cluster under this managed device, the port numbers that sends is the SNMP port numbers (if command switch self then is the SNMP port numbers of self) of mapping; Illustrate as follows, as needs management be member switch E, the SNMP port numbers that it shines upon in this cluster is 19504, then this SNMP message is sent to command switch 100.1.1.2, the port numbers of transmission is 19504.
Command switch just can be judged the managed device that the requesting party will visit according to the SNMP port numbers of mapping like this, the SNMP message is transmitted processing module message is transmitted to managed device, managed device receives issues command switch after message is handled, after command switch is received message, the requesting party is issued in forwarding, finishes the random access of requesting party to equipment.
Also might initiatively report command switch by member switch, use Trap (trap) message of SNMP, generally be used to describe the generation of a certain incident; Then command switch is transmitted to this message the destination address that reports.
What the embodiment of the invention provided comprises following step based on snmp protocol to the way to manage of large-scale Ethernet switch in the cluster management:
1, in a cluster management, command switch distributes the SNMP port numbers of a mapping respectively for its all member switch, the SNMP port numbers that command switch is monitored all mapping SNMP port numbers of distributing to member switch and self used, member switch is monitored the SNMP port numbers that self uses; All switches are all supported snmp protocol;
2, have a SNMP message to transmit processing module on command switch: this forwarding module is mainly finished the SNMP message of reception from the requesting party; Message is transmitted to managed device; The SNMP message that managed device is replied is transmitted to the requesting party again; Concrete steps are as shown in Figure 2:
Step 201: the requesting party sends the SNMP message, sends to the command switch of the affiliated cluster of managed device, and the port numbers of transmission is the SNMP port numbers of the mapping of transmission purpose member switch; If supplicant access is exactly command switch, then send to 161 ports of command switch, (default SNMP port numbers is 161 to the 161 SNMP port numbers of using for command switch self, suppose that hereinafter the SNMP port numbers that command switch oneself uses is exactly 161, the SNMP port numbers that member switch uses also is 161); The SNMP message that reception sends from the requesting party;
Step 202: command switch judges that according to the port numbers that receives message message is given own processing still gives the member switch processing; If port numbers is not 161, but be its mapped port number of distributing to member switch, execution in step 204; If port numbers is 161, then execution in step 203;
Step 203: command switch oneself is handled this SNMP message, execution in step 206;
Step 204: the port numbers of the SNMP message that command switch receives is not 161, but is its mapped port number of distributing to member switch; Port numbers according to mapping is determined the member switch that message is forwarded, and message is transmitted processing module and set up keyword for transmitting, and at this moment, the source IP address source port number and the keyword message of this message is stored; Message is transmitted processing module and is changed the destination slogan of the transmission of this SNMP message into default 161 port numbers, transmits this message and gives corresponding member switch, receives that carrying out normal SNMP behind the SNMP message handles;
Step 205: after member switch is handled SNMP is replied message and sends, the SNMP message that command switch receive to be replied, and by canned data according to keyword search; Take out source IP address and source port number in this information, and this message is issued source IP address, the port of transmission is a source port number;
Step 206: command switch sends a reply message and gives the requesting party.
In whole implement process, message is transmitted processing module and has only been finished message forwarding work, and true processing is also at accessed equipment, and is little to the load of command switch.Realized cluster management method based on snmp protocol.
In addition, also can command switch distribute each member's mapping SNMP port numbers after, what notify that all member machines monitor is own SNMP port numbers of being shone upon.The destination slogan of the message of giving member switch of command switch forwarding is the mapping SNMP port numbers of member switch like this, also can finish above-mentioned functions.
In sum, adopt cluster management mode, effectively solved public network IP address waste or shortcoming that can't remote management apparatus, for network management system provides a kind of cost-effective method based on snmp protocol.In addition, the present invention does not revise the snmp protocol of standard, as long as member switch is supported the snmp protocol of standard, just can manage, and is compatible strong.
