Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention is a realization scheme that can use dial switch to select switch to access different local area network, and adds dial switch on the switch to control and manage the network actually accessed on the switch, which has the advantages of simple use and convenient management, and the basic realization mode is:
1. dividing an operation interface on the switch into three areas: a dial-up switch area a, a lan connection port area B and an internal use port area C, as shown in fig. 1;
2. the dial switch area a and the lan connection port area B are in a one-to-one correspondence relationship as shown in fig. 2, and it is defined that when the dial switch is dialed to "1", the corresponding port on the lan connection area B is enabled, and when the dial switch is dialed to "0", the corresponding port on the lan connection area B is disabled, and at most only one dial switch can be dialed to "1" position at the same time.
3. The position of the dial switch may determine whether the corresponding lan port is valid, and taking the dial switch No. 1 and the lan port No. 1 as an example, the specific implementation manner is as shown in fig. 3:
in the actual working process of the switch, a dial switch area A and a local area network connection area B share a circuit back board, 8 identical backward diodes are arranged in the circuit principle board, the switching between the '1' position and the '0' position of the dial switch actually controls whether the backward diodes are connected into the circuit, and when the diodes are connected into the circuit, the reverse directions of the diodes are different, so that data signals cannot be connected onto the back board even if the corresponding ports are connected with RJ45 network cables; when the dial switch is switched to the '1' position, the diode is not connected into the circuit, and the corresponding local area network port can be normally connected into the backboard circuit, so that data receiving and sending are realized.
4. When the local area network connection device is used, the local area network connection area B is connected with all possible local area network segments, the local area network segments actually accessed by the terminal equipment in the area C are controlled through the corresponding switches in the dial switch area A, namely, the local area network segments in which the area B really takes effect, and through the mode, the terminal equipment connected with the area C of the internal use port can be more efficiently and conveniently operated on different local area network segments, so that the local area network connection device is simpler and more flexible.
To facilitate understanding of the present invention, the following takes the principle of the method for implementing the switch to selectively access the lan by using the dial switch of the present invention, and combines the following switching from the network segment corresponding to port No. 3 to the network segment corresponding to port No. 2 in the lan connection area B, with reference to fig. 4 and the implementation manner as follows:
1. all dial switches on the switch in the initial state are positioned at '0' positions, the switch is not accessed into any network segment, the local area network connection area B is connected to all local area network segments which can be used by using network cables, and the internal use port B area is connected with terminal equipment which needs to work in different network segments;
2. electrifying the switch, dialing the dial switch corresponding to the port of the local area network connection area B2 to the position of '1', wherein the network segment really accessed by the switch is the local area network connected with the port of the area B2, checking all terminal devices, and working under the network segment corresponding to the port of the area B2;
3. when the terminal equipment connected with the C area needs to be switched from a network segment No. 2 to a network segment No. 3, firstly, a dial switch corresponding to a port No. 2 is dialed to a position of '0', the terminal equipment is checked not to work in any network segment, then, the dial switch corresponding to the port No. 3 is dialed to a position of '1', the switch is accessed to the network segment No. 3, and at the moment, the network working state of the terminal equipment is checked to work in a local area network segment corresponding to the port No. 3;
4. after the use is finished, all dial switches are readjusted to the '0' position, and the network segment to be accessed is reselected when the terminal equipment is used next time.

Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and scope of the present invention, and these modifications or substitutions are within the scope of the present invention/any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention.
