Description

  The present invention relates to a setting data update method in a network relay device.

When updating setting data such as router related setting data, telephone related setting data, and wireless communication related setting data in a network relay device such as a VoIP (Voice on Internet Protocol) router device, the network relay device is currently set. It is common to update existing data with setting data input from a user interface such as a web browser by a user. At this time, the network relay device stores the setting data as a setting file in response to a setting data update instruction from the user, and updates the setting data read from the setting file when the network relay device restarts. Normally, since the network relay device relays a packet based on the setting data, when the packet relay is continuously executed, the setting data cannot be updated and a restart is necessary. It was. For example, Non-Patent Documents 1 and 2 describe a setting method and a manual in which setting data is updated when a user inputs setting data from a Web browser and restarts the apparatus.
