Generating host tables for devices with SiteConfig
When you have successfully assigned devices and applied planned network settings
to interfaces, it is an indication that host table information, as currently captured in the
system description, is valid and that you are ready to have SiteConfig assemble the
host table information into a hosts file. Your options for placing this host table
information on devices are as follows:
• If you do not want SiteConfig to manage your host table information, you can
manage it yourself. This is typically the case if your facility has an existing hosts
file that contains host table information for devices that are not in the SiteConfig
system description. In this case, you can have SiteConfig generate a single hosts
file that contains the host table information for the devices in the system
description. You can then copy the desired host table information out of the
SiteConfig hosts file and copy it into your facility hosts file. You must then
distribute your facility hosts file to devices using your own mechanisms.
• If you want SiteConfig to manage all information in hosts files on devices, you can
have SiteConfig copy its hosts file to devices. In so doing, SiteConfig overwrites
the existing hosts files on devices. Therefore, this requires that all devices that have
name resolution through the hosts file be configured accordingly in the SiteConfig
system description.
If you choose to have SiteConfig write hosts files to devices, the process consumes
system resource and network bandwidth. Therefore you should wait until you have
verified the information for all devices/interfaces in the host file, rather than updating
hosts files incrementally as you discover/assign devices.
SiteConfig does not automatically deploy hosts files to managed devices as you add
or remove devices. If you add or remove devices from the system description, you
must re-deploy the modified hosts file to all devices.
Generating host tables for devices with SiteConfig
Prerequisites for this task are as follows:
• Planned control network settings are applied to control network interfaces and
devices are communicating on the control network as defined in the system
description.
• Interfaces for networks that require name resolution via the hosts file, such as the
FTP/streaming network, have settings applied and are communicating.
• You have viewed host names, as currently defined in the system description, and
determined that they are correct.
• The control point PC is added to the system description so that it is included in the
host tables generated by SiteConfig.
1. In the Network Configuration | Networks tree view, select a network, site, or system
node.
2. Click View Hosts file .
A Hosts File Contents window opens that displays the contents of the hosts file as
currently defined in the system description.
3. Verify the information in the hosts file.
