Is accessed, and it is checked whether the message is a normal SNMP message (S11). If normal (Yes in S11), a command character string is extracted from the SNMP message (S12), and the extracted command character string is transmitted to the command analysis processing unit 231 of the command processing function block 23 (S1).
3) Send a normal response to the SNMP manager (S1)
4). On the other hand, if abnormal (No in S11),
An error response is sent to the SNMP manager 1 (S15).

Next, the execution result obtaining operation will be described. FIG. 4 is a flowchart showing the operation of the execution result acquisition MIB processing unit 222. The execution result acquisition MIB processing unit 222 is activated when the execution result acquisition MIB 212 is accessed, and first checks whether the SNMP message is normal (S21). If normal (Y at S21)
In the case of "es", the execution result stored in the execution result storage memory 224 is returned to the SNMP manager 1 (S2).
2). If abnormal (No in S21), SNM
An error response is sent to the P manager (S23). further,
When the state of the output type storage memory 225 indicates that there is page control, a request for outputting the next page is made to the display processing unit 233.

Next, the output type obtaining operation will be described. FIG. 5 is a flowchart showing the operation of the output type acquisition MIB processing unit 223. Output type acquisition MIB
The processing unit 223 is activated when the output type acquisition MIB 213 is accessed, and first checks whether it is a normal SNMP message (S31). If normal (S31
In the case of “Yes” at step S), the output type stored in the output type storage memory 225 is returned to the SNMP manager 1. If it is abnormal (No in S31), SNM
An error response is sent to the P manager.

Next, the command analysis operation will be described. FIG. 6 is a flowchart illustrating the operation of the command analysis processing unit 231. The command analysis processing unit 231 is activated when a character string is transmitted from the command reception processing unit 221 and analyzes the transmitted command character string (S4).
1). As a result of the analysis, if the command is a supported command (Yes in S42), the command parameters are further checked, and if the command is normal (Yes in S43).
s), the command processing unit 232 of the analyzed command
Is started (S44). Unsupported command (No in S42) or parameter error (S4
In the case of No at 3), an error display is performed using the display processing unit 233.

Next, the command processing operation will be described. FIG. 7 is a flowchart illustrating the operation of the command processing unit 232. The command processing unit 232 executes the exchange control based on the designated parameters (S51), and displays the execution result using the display processing unit 233 (S52).

Next, the display processing operation will be described. FIG. 8 is a flowchart showing the operation of the display processing unit 233. The display processing unit 233 checks whether it is a command or a request via SNMP (S61). If the command is via SNMP (Yes in S61), the display contents are stored in the execution result storage memory 224 (S62). . If not via SNMP (No in S61), the execution result is displayed on the control terminal 3 screen (S63). Next, it is checked whether or not the execution result has page control (when the display content does not fit in one SNMP message) (S64), and when there is page control (Yes in S64), the output type storage memory 225. Is set to have page control (S6).
5) Wait until there is a next page output request (S66). When a next page output request is made (Yes in S67), the next display content is output. If there is no page control (No in S67), the output type storage memory 22
5 is set in the page control.

Next, a second embodiment will be described with reference to the accompanying drawings. The second embodiment relates to a recording medium on which a control program is recorded. This shows a case where the control software 24 shown in FIG. 1 is externally supplied to the exchange 2 as a control program recorded on a recording medium.

FIG. 9 is a configuration diagram of an example of a recording medium and its driving device. Referring to FIG. 9, the recording medium driving device includes a CPU (Central Processing).
(Unit) 31, an input device 32, and a storage device 33, and the CPU 31 controls the exchange 2 described above. Further, a program for causing the exchange 2 to perform the operations shown in the sequence charts and flowcharts of FIGS. 2 to 8 described above is recorded on the recording medium 34.

Next, the operation of the driving device will be described. First, when a program load instruction is input from the input device 32 to the CPU 31, the CPU 31 reads a program from the recording medium 34 and writes the read program into the storage device 33. Next, the CPU 31 is input from the input device 32.
When a program run command is input to the CPU 31, the CPU 31 reads a program from the storage device 33 and controls the exchange 2 according to the read program. Since the contents of the control have been described above, the description is omitted.

In the present invention, the exchange 2 has been described as an example of a device to be controlled. However, the present invention is not limited to the exchange 2, and any device having an exchange function may be replaced with, for example, a router or a workstation. It can be used.
