Configuring System Data Communication

The settings described in this section are required to use the sub line for performing DNS name resolution and data communication via a proxy. Administrator privileges are required to specify these settings.


The DNS server address setting and proxy settings for the sub line can only be used for specific system data communication, such as using the sub line to access a firmware distribution server. They cannot be used for a regular internet connection. When using a DNS server or proxy server for the sub line for applications other than system data communication, register the addresses and port numbers to use with the sub line in the settings of the main line.
