Description

  The present invention relates to a switch network setting method, a switch using the switch, and a computer-readable recording medium. More specifically, the present invention relates to a tethering connection between a switch and a terminal. (I) receiving an IP address of the management server from the terminal by the set tethering connection, and receiving switch setting information from the management server using the received IP address of the management server, or (ii) The switch setting information received from the management server by the terminal is received from the terminal through the set tethering connection, or (iii) the setting from the management server that has received the IP address of the switch broadcast by the terminal. With a tethered connection After receiving the configuration information of pitch, the switch, the method comprising the step of setting a network in accordance with the setting information of the received switch, to a switch and a computer-readable recording medium using the same.

  The switch can identify the intended object of data as a communication device connecting the network units, and can simultaneously transmit and receive data, so that data can be sent more quickly than the hub. The switch is classified according to the network layer, and switches packets by referring to a MAC address, an IP address, TCP / UDP port information, and the like.

  When a new switch is connected to a network (for example, VLAN), the network must first be set in accordance with the function of the switch to be implemented on the network. An IP address is assigned to a switch in which network setting is performed from a DHCP (Dynamic Host Configuration Protocol) server on the network.

  Recently, ZTI (Zero Touch Installation) technology has appeared in order to make switch network settings easy. When the switch is connected to the network, the ZTI technology acquires the management server IP address from the DHCP server, connects to the management server using the acquired management server IP address, and configures the network settings from the management server. This technology receives information and executes network settings. ZTI technology can save time and effort for a user to input switch setting information.

  FIG. 1 is a conceptual diagram showing a method for setting a switch network using the ZTI technology.

  Referring to FIG. 1, when a new switch 20 is connected to the network, it is preferentially connected to the DHCP server 30. That is, when the switch 20 finds the DHCP server 30 (DHCP discover), an IP address is assigned from the DHCP server 30 and the IP address of the management server 10 can also be received (a in FIG. 1). The new switch 20 can also use the IP address of the management server to access the management server 10 (b in FIG. 1) and receive switch setting information from the management server 10 (c in FIG. 1).

  However, even with such a ZTI method, there is a limit that it is difficult to set a switch when the network configuration is complicated. For example, if there are two or more VLANs (Virtual LANs) and a network with redundant paths (Redundancy-path) is configured, all newly connected switches will default to all ports at the time of product shipment. Since it is set to VLAN, it may not be possible to find a DHCP server on another VLAN.

  Therefore, there is a demand for a technology that can easily perform switch network settings even when a DHCP environment is not established.

  The object of the present invention is to solve all the above-mentioned problems.

  Another object of the present invention is to enable easy network setting of a switch even when a DHCP environment is not established.

  In the present invention, the switch uses a tethering connection (a mobile computer with a built-in communication terminal (such as a smartphone connected to a mobile phone line) as an external modem to connect another computer or the like to the Internet. If the DHCP server cannot be found by accessing the management server and receiving the switch setting information using the IP address of the management server acquired from the terminal (hereinafter referred to as “tethering” or “tethering connection”). Another object is to be able to quickly and easily perform switch network settings.

  In addition, the present invention allows the switch to perform network setting of the switch more quickly and easily even when the DHCP server is not found by receiving the switch setting information received from the management server by the terminal from the terminal through the tethering connection. Another purpose is to be able to.

  In addition, the present invention finds a management server in a local area network by broadcasting the IP address of the switch, so that the management server in the local area network can be obtained without separately acquiring the IP address of the management server. It is another object of the present invention to enable the network setting of the switch to be received more quickly and easily.

  In order to achieve the above object, the main configuration of the present invention is as follows.

  FIG. 2 is a block diagram showing a configuration of a switch according to an embodiment of the present invention.

  Referring to FIG. 2, the switch 100 according to an embodiment of the present invention includes a communication unit 110, a network setting unit 120, and a control unit 130.

  The communication unit 110 is configured to communicate with the terminal 300 or the management server 200 through tethering connection, and to communicate with a plurality of devices including the management server 200 through a set network when tethering is lost. First, the communication unit 110 can set a tethering connection when the switch 100 is connected to the terminal 300 via a wired interface (for example, USB) or a wireless interface. When connected by a wired interface, the communication unit 110 can set the terminal 300 and an Ethernet (registered trademark) interface. In contrast, the communication unit 110 may provide a wireless interface through a Bluetooth (registered trademark) tethering function. When the tethering connection is set, the communication unit 110 can receive gateway information of the wireless network connected to the terminal 300 from the terminal 300. The switch 100 can set the received gateway information and connect to the Internet through tethering connection.

  The communication unit 110 can acquire switch setting information by various methods described below. First, an embodiment in which the IP address of the management server 200 is obtained and switch setting information is received from the management server 200 will be described.

  FIG. 3 is a diagram illustrating an embodiment in which the switch acquires the IP address of the management server and receives switch setting information from the management server.

  The communication unit 110 can receive the IP address of the management server 200 from the terminal 300 through the tethering connection, and can receive switch setting information from the management server 200 using the received IP address of the management server 200.

  More specifically, with reference to FIG. 3, when the tethering connection is established with the switch 100, the terminal 300 can serve as a DHCP server and can assign an IP address to the switch 100. Further, the terminal 300 can acquire the IP address of the management server 200. At this time, the terminal 300 can also obtain the IP address of the management server 200 by user input. When the terminal 300 knows the IP address of the DHCP server (not shown), the IP address of the management server 200 can be acquired by requesting the DHCP server. As described above, when the IP address of the management server 200 is acquired, the terminal 300 can transmit the acquired IP address of the management server 200 to the switch 100 (a in FIG. 3).

  In this case, the communication unit 110 of the switch 100 can receive the assigned IP address of the switch 100 and the acquired IP address of the management server 200 from the terminal 300 by the set tethering connection (see FIG. 3 a). The communication unit 110 can connect to the management server 200 by using the assigned IP address of the switch 100 and the IP address of the management server 200 (b in FIG. 3). Can be received (c in FIG. 3). Here, the switch setting information means parameter values necessary for the switch 100 to operate normally on the network in accordance with a network topology defined in advance. For example, the switch setting information may include at least a part of gateway information, DHCP server information, DNS server information, and port information of a network managed by the management server 200.

  On the other hand, when the switch 100 is connected, the management server 200 can check whether the switch 100 is registered in the management server 200 based on the identification information of the switch 100. When the identification information of the switch 100 is not registered in the management server 200, the management server 200 can register the identification information of the switch 100 in the management server 200 and give the switch setting information to the switch 100.

  On the other hand, when the terminal 300 acquires the IP address of the DHCP server, the communication unit 110 can also receive the switch setting information directly from the DHCP server through the set tethering connection.

  When the communication unit 110 receives the switch setting information, the network setting unit 120 can set the network of the switch 100 according to the received switch setting information, as will be described later. When the tethering connection is disconnected, the switch 100 can communicate with the management server 200 and other devices (for example, a DHCP server) according to the set network (d in FIG. 3).

  As described above, according to the present invention, the terminal 300 transmits the IP address of the management server 200 to the switch 100 through the tethering connection. Thereafter, the switch 100 accesses the management server 200 using the IP address of the management server 200 and receives switch setting information. Therefore, even when a DHCP server is not found, the network setting of the switch 100 can be performed more quickly and easily.

  Unlike the above-described embodiment, the terminal 300 can receive switch setting information for network setting of the switch 100 and transmit it to the switch 100 through tethering connection. In the following, these examples will be described.

  FIG. 4 is a diagram showing another embodiment in which a terminal receives switch setting information and transmits it to the switch.

  The communication unit 110 can receive the switch setting information received from the management server 200 by the terminal 300 from the terminal 300 through the set tethering connection. More specifically, with reference to FIG. 4, the terminal 300 can serve as a DHCP server and assign an IP address to the switch 100. Further, the terminal 300 can acquire the IP address of the management server 200. If the terminal 300 knows the IP address of a DHCP server (not shown) provided separately, the IP address of the management server 200 can be acquired by requesting the DHCP server. In this way, when the IP address of the management server 200 is acquired and an IP address is assigned to the switch 100, the terminal 300 can connect to the management server 200 using the acquired IP address of the management server 200. it can. Then, the IP address of the assigned switch can be transmitted to the management server 200 (a in FIG. 4). Further, the terminal 300 can directly receive the switch setting information from the management server 200 (b in FIG. 4).

  When the terminal 300 is connected, the management server 200 can confirm whether the switch 100 is registered in the management server 200 based on the identification information of the switch 100. When the tethering connection is made between the terminal 300 and the switch 100, the identification information of the switch 100 can be acquired from the switch 100 or acquired by a user input. When the identification information of the switch 100 is not registered in the management server 200, the management server 200 can register the identification information of the switch 100 in the management server 200 and give the switch setting information to the terminal 300.

  The terminal 300 can transmit the received switch setting information to the switch 100 through the tethering connection. In other words, the communication unit 110 of the switch 100 can receive switch setting information from the terminal 300 through the set tethering connection.

  On the other hand, when the terminal 300 acquires the IP address of the DHCP server, the terminal 300 can also receive switch setting information from the DHCP server. In this case, the communication unit 110 of the switch 100 can be received from the DHCP server by the terminal 300. The received switch setting information can be received from the terminal 300 through the set tethering connection.

  When the communication unit 110 receives the switch setting information, the network setting unit 120 can set the network of the switch 100 according to the received switch setting information, as will be described later. When the tethering connection is disconnected, the switch 100 can communicate with the management server 200 and another device (for example, a DHCP server) according to the set network (d in FIG. 4).

  In the above-described embodiment, the management server 200 may be a cloud server. The cloud server is located far away from the switch 100 and can have a predetermined IP address. The switch 100 can acquire the IP addresses of these cloud servers by the method described above. However, since the embodiment described above has a disadvantage that it is necessary to acquire the IP address of the management server 200, the embodiment in which the process of acquiring the IP address of the management server 200 is unnecessary will be described below. To do. That is, in the following, an embodiment in which the terminal 300 broadcasts the IP address of the switch 100 and receives switch setting information from the management server 200 will be described.

  FIG. 5 is a diagram showing another embodiment in which the terminal broadcasts the switch IP address and receives the switch setting information from the management server.

Referring to FIG. 5, the communication unit 110 can receive switch setting information through the set tethering connection from the management server 200 that has received the IP address of the switch 100 broadcast by the terminal 300. More specifically, when a tethering connection is made with the switch 100, the terminal 300 can perform the role of a DHCP server and assign an IP address to the switch 100. The terminal 3 00 may broadcast the IP address of the switch 100 allocated to the local area network each contained in (LAN) device (200, 200 ', 200'') (Fig. 5 A). The management server 200 receives the broadcasted IP address of the switch 100, and can directly transfer the switch setting information to the switch 100 by the set tethering connection using the IP address of the switch 100 (FIG. 5 b). In this case, the communication unit 110 of the switch 100 can receive switch setting information from the management server 200 through the set tethering connection (b in FIG. 5).

  On the other hand, when the DHCP server receives the IP address of the switch 100 broadcast by the terminal 300, the DHCP server directly switches the setting information of the switch through the set tethering connection using the IP address of the switch 100. 100 can also be transferred. In contrast, the DHCP server may provide the switch setting information to the terminal 300 so that the terminal 300 transmits the switch setting information to the switch 100 through the set tethering connection.

  On the other hand, the terminal 300 can broadcast the IP address of the switch 100 and the identification information of the switch 100, and the management server 200 confirms whether the switch 100 is registered in the management server 200 based on the received identification information. be able to. When the tethering connection is made between the terminal 300 and the switch 100, the identification information of the switch 100 can be acquired from the switch 100 or acquired by a user input. When the identification information of the switch 100 is not registered in the management server 200, the management server 200 can register the identification information of the switch 100 in the management server 200 and give the switch setting information to the switch 100.

  When the communication unit 110 receives the switch setting information, the network setting unit 120 can set the network of the switch 100 according to the received switch setting information, as will be described later. When the tethering connection is disconnected, the switch 100 can perform communication between the management server 200 and another device (for example, a DHCP server) according to the set network.

  As described above, according to the present invention, the terminal 300 broadcasts the IP address of the switch 100 to find the management server 200 in the local area network without acquiring the IP address of the management server 200 separately. The switch setting information can be received, and the network setting of the switch 100 can be performed more quickly and easily.

  Further, the communication unit 110 performs a function that enables the switch 100 to communicate with other devices or modules. For example, the communication unit 110 can communicate with other devices via a wireless network or a wired network.

  The network setting unit 120 is configured to set the switch network in accordance with the received switch setting information. Specifically, the network setting unit 120 can set the gateway information, the DHCP server information, the DNS server information, and the port information of the network managed by the management server 200, which is the received switch setting information. it can. Further, the switch 100 can be connected to the DHCP server after the tethering connection is cut, but can also receive additional information from the DHCP server and set the network.

  The control unit 130 executes a function of controlling the data flow between the communication unit 110 and the network setting unit 120. That is, the control unit 130 controls the communication unit 110 and the network setting unit 120 so as to execute unique functions by controlling the data flow between the components of the switch 100.
