
Configuration Control
The Configuration Control attribute is used to control network configuration options.

Interface Configuration
This attribute contains the configuration parameters required to operate as a TCP/IP node.
To modify the Interface Configuration attribute, get the Interface Configuration attribute first,
change the desired parameters, then set the attribute.
The TCP/IP Interface Object applies the new configuration upon completion of the Set service. If the
value of the Startup Configuration bits (Configuration Control attribute) is 0, the new configuration
is stored in non-volatile memory.
The device does not reply to the set service until the values are safely stored to non-volatile memory.
An attempt to set any of the components of the Interface Configuration attribute to invalid values
results in an error (status code 0x09) returned from the Set service.
If initial configuration is obtained via BOOTP or DHCP, the Interface Configuration attribute
components are all 0 until the BOOTP or DHCP reply is received.
Upon receipt of the BOOTP or DHCP reply, the Interface Configuration attribute shows the
configuration obtained via BOOTP/DHCP.

Host Name
The Host Name attribute contains the device’s host name.
The host name attribute is used when the device supports the DHCP-DNS Update capability and has
been configured to use DHCP upon start up.
The mechanism allows the DHCP client to transmit its host name to the DHCP server. The DHCP
server then updates the DNS records on behalf of the client.
