3 is a diagram illustrating an MIB compilation UI according to an exemplary embodiment of the present invention. FIG. 3 is a MIB compilation UI providing MIB management function. It can be useful when setting SNMP values by precompiling a MIB to be provided by a virtual device. In addition, you can load and unload MIB modules to use only specific MIBs without using all compiled MIBs.
4 is a diagram illustrating a UI in which a user can define an MIB value to be provided in a virtual device according to an exemplary embodiment of the present invention. The user can set the MIB value to be provided to be fixed, and the information to be changed such as traffic monitoring can be set to be automatically changed by setting the value change period, the change range, and the like. Automatic value changes are available in list and string formats as well as numeric formats.
5 is a diagram illustrating a UI for defining a structure of a Trap periodically generated in a virtual machine according to an embodiment. The user can predefine the Trap structure to determine what Trap will be generated in the virtual machine. Using Trap defined in MIB makes it easier to define Trap.
6 to 10 are views illustrating a UI for defining a device to be used as a virtual device according to an exemplary embodiment. Referring to FIG. 6, the user defines equipment by inputting manufacturer information and model information of the equipment to be provided by the virtual equipment agent. The device definition also selects the MIB to be provided by the current device. As shown in FIG. 7, the user can check and select the MIB value to be provided from the equipment in the tree. Also, a part or all of the values of the MIB can be fetched from the actual equipment, and the method is illustrated in FIG. As shown in FIG. 8, when a user creates a profile of an actual device to import an MIB value and selects and imports an MIB to be imported, the user obtains the value from the actual device and displays it. . By importing all the MIB values of the actual equipment, you can virtualize and test a large number of equipments like the actual equipment.
In the device definition, a Trap to be provided by the virtual device is also designated, as shown in FIG. As shown in FIG. 9, a user can create and set a Trap instance to be generated in a virtual device using a predefined Trap definition. Trap instances have a lot of binding values and can vary in value depending on the actual equipment situation, making it difficult to create them. Therefore, Trap generated from the equipment can be captured and used as shown in Fig. 10 for easy Trap instance creation. As shown in FIG. 10, the user can start the Trap server and capture the Trap generated from the real equipment. If the user wants to use the Trap, he can import it by dragging it into the Trap value selection window. In this way, it is possible to test the amount of traps that can be processed by the network management system and the normal processing by setting traps to occur in the virtual equipment.
11 to 13 are views showing a UI for managing a virtual equipment agent to operate the virtual equipment according to an embodiment. When the agent IP is set to the agent and the agent is started, the agent is registered in the manager. After that, the manager controls all the operations of the agent. Since the virtual device operates with packet capturing, the MAC address of the interface to capture packets in the virtual device of the agent must be set. Before activating the agent, you must first configure the device information to be executed by the agent. As shown in FIG. 12, the user sets the model of the equipment to be operated in the agent, the IP address range, the SNMP community, and the like. Also, if the network management system and the agent are on different subnets, enter the gateway address in the routing table to be used by the virtual device. Also, if you want to send Trap to the network management system, set the IP address of the network management system in the Trap host. When a virtual machine is started, virtual machines as many as the number of machines specified in the machine configuration are operated, and the status of each virtual machine can be checked and set through the machine status. FIG. 13 shows a list of virtual machines currently operating in the selected agent. You can start or stop the SNMP, Trap, and ICMP processes for a specific device or device.
14 is a diagram illustrating a virtual equipment agent UI according to an embodiment. The user can set the server information to be accessed through the virtual equipment agent UI and the amount of memory to be used by the agent, and operate the agent.
