NetConfig — Instruction Manual
In summary, NetConfig works on a flat, isolated LAN without the need for
special network configuration. To work properly in any other network
topology, network system configuration outside the scope of this manual
may be required. Work with your network administrator if you wish to use
NetConfig in other network environments.
The NetConfig application is a powerful tool. A NetConfig user can easily
change the IP addresses of NetConfig compliant devices on a network, and
can change the software installed on those devices. For responsible facility
engineering staff these capabilities are extremely useful for bringing up and
configuring systems. A person with malicious intent, however, can use
these same capabilities to take any or all NetConfig compliant devices on
the network offline, possibly seriously disrupting facility operations.
It is assumed that those using NetConfig are indeed legitimate authorized
users, and are working in premises which are physically secure/restricted
and protected from extraneous network penetration, either by physical iso-
lation or behind a company firewall.
NetConfig can be used by several different Grass Valley product lines to
load software to various devices over the network. The same NetConfig
application software is used by all the product lines, but different kinds of
device software will need to be loaded to different devices. Identifying
what type and version of software is available to NetConfig to load is
accomplished using separate files included with each specific product line
release. These files provide NetConfig paths to the locations of the software
appropriate for each device. Only the path and software files for that par-
ticular product line will be included in the NetConfig software bundled
with that product's software releases. These files are installed onto the PC
along with the NetConfig application itself.
In earlier versions of NetConfig, files appended with .sw3 were used to
identify the type and location of device software. In newer versions, .xml
files are used. NetConfig supports either or both mechanisms. The organi-
zational tree structure displayed by NetConfig from which you choose
which software version to load is determined by these files.
For example, if you install the NetConfig application provided with one
product, and then install NetConfig provided with a different product, the
new product's .xml or .sw3 files are simply added to that PC, and do not
overwrite files of the other product line. NetConfig can still load the other
product's software to those devices. The software load tree structure will
show both the new product line device software and the previous product
line device software.
