Abstract
The invention discloses a method for positioning an MAC address in a switching network, which comprises the following steps: step 1: using a gateway to send multicast discovery packets to all internal network ports; step 2: using a switch to search an MAC address table after receiving the discovery packets; step 3: if the target MAC address is found, implementing the step 5, otherwise, implementing the step 4; step 4: leading the path cost value to plus 1, then forwarding to all the ports except the ports receiving the discover packets, and implementing the step 8; step 5: if the target MAC address is in the ports receiving the discovery packets, implementing the step 8, otherwise, implementing the step 6; step 6: leading the path cost value to plus 1, and then forwarding to the target port; step 7: using the gateway to receive a response that the switch finds out the target MAC address; and step 8: quitting the treatment process, and using the lower-level switch to continue the treatment according to the process. The method is simple and easy to operate and has no influence on other applications.
Description
Technical field
The present invention relates to the method for a kind of positioning MAC (Media Access Control, medium access control) address, particularly relate to the method for positioning MAC address in a kind of switching network.
Background technology
In the practical application of a lot of network bar users, usually need the switch ports themselves at certain MAC Address or place, IP address be closed.After knowing destination address place switch ports themselves; It is very simple to close certain port; But in a complex network, often be difficult to know that which platform switch is destination address be connected on, if the wrong port of having closed certain switch causes normal users to surf the Net probably.Thus, the difficult point that this function realizes is definite switch ports themselves that directly links to each other with target machine, i.e. target port.Implementation method has multiple; MAC/PORT (port) binds as all edge switch are carried out, the port protection setting; Whether perhaps set the type of each port by the user, be methods such as edge port, though these methods have reduced technical difficulty; But also reduced ease for use simultaneously, and possibly influence other application.The present invention has well solved this difficult problem through the interlock of gateway and switch.
Summary of the invention
Technical problem to be solved by this invention provides the method for positioning MAC address in a kind of switching network, and it has strengthened ease for use, and does not influence other application.
The present invention solves above-mentioned technical problem through following technical proposals: the method for positioning MAC address in a kind of switching network is characterized in that it may further comprise the steps:
Step 1: gateway sends the discovery bag of a multicast to its all Intranet ports, finds to comprise destination-mac address and the path cost that will seek;
Step 2: switch is received and is found bag back search mac address table;
Step 3: judge whether to find destination-mac address, if find destination-mac address, then execution in step five; If do not find destination-mac address, then execution in step four;
Step 4: the path cost value is added 1, receive all of the port forwarding of finding bag to removing then, execution in step eight then;
Step 5: judge whether that in receiving the port of finding bag, if in receiving the port of finding bag, then execution in step eight; If in receiving the port of finding bag, then execution in step six;
Step 6: the path cost value is added 1 back transmit to target port; Path cost value and destination port number in destination-mac address that gateway report is found, the discovery bag received;
Step 7: gateway is received the answer of the switch of finding out destination-mac address, selects the maximum switch of path cost value, sends the order of closing target port to this switch;
Step 8: withdraw from handling process, subordinate's switch will continue by flow processing.
Positive progressive effect of the present invention is: the present invention is for method simple possible, the efficiently and accurately of positioning MAC address in switching network.
Description of drawings
Fig. 1 is an algorithm flow chart of the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
As shown in Figure 1, the method for positioning MAC address may further comprise the steps in the switching network of the present invention:
Step S101: gateway sends the discovery bag of a multicast to its all Intranet ports, finds to comprise destination-mac address and the path cost (this moment, path cost was 0) that will seek;
Step S102: switch is received and is found bag back search mac address table;
Step S103: judge whether to find destination-mac address, if find destination-mac address, execution in step S105 then; If do not find destination-mac address, then execution in step 104;
Step S104: the path cost value is added 1, receive all of the port forwarding of finding bag, execution in step S108 then to removing then;
Step S105: judge whether in receiving the port of finding bag, if in receiving the port of finding bag, execution in step S108 then; If do not have in receiving the port of finding bag, then execution in step S106;
Step S106: the path cost value is added 1 back transmit to target port; Path cost value, destination port number in destination-mac address that gateway report is found, the discovery bag received;
Step S107: gateway is received the answer of the switch of finding out destination-mac address, selects the maximum switch of path cost value, sends the order of closing target port to this switch;
Step S108: withdraw from handling process, subordinate's switch will continue by flow processing.
Though more than described embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these execution modes.Therefore, protection scope of the present invention is limited appended claims.
