Config Generator (CG) is a free tool from SolarWinds, which puts you in charge of controlling changes to network routers and other SNMP devices.  You can get started without having to learn complex syntax.

How to Install the SolarWinds Network Config Generator

I find the hardest part of the install is remembering where I downloaded the zip file!  Otherwise I just followed the standard procedure, I extracted the application, which is a single file, click the licence agreement, and let the InstallShield Wizard perform the setup.

After the install completes, the Config Generator launches, and you are ready to begin.  If you need ‘find’ the application later look on the start menu, or if all else fails navigate to:

C:\Program Files (x86)\SolarWinds\ConfigGenerator

Should you need to uninstall, then go to the Control Panel, Programs, scroll down to ‘S’ for SolarWinds Network Config Generator.  It’s a sign of a good freeware program that it uninstalls easily and completely.

Recommendation: Get extra templates for your Network Config Generator from the Thwack forum.

Example of NCG in Action

The Network Config Generator is handy for automatically configuring Cisco routers, which usually have 3000+ lines of code.

Example Templates for Your NCG

This is a base change template to act as a starting point for other templates.
TODO – replace with details of the device platform the template is targeted at.

NCM Node
The node the template will operate on. All templates require this by default. The target node is selected during the first part of the wizard so it will not be available for selection when defining variable values.

SomeVariable1 Label
Enter variable description and helper text here.

SomeVariable1 Labe2
Enter variable description and helper text here.

script BaseChangeTemplate(
NCM.Nodes @ContextNode,
string @SomeVariable1,
string @SomeVariable2 )
//TODO – insert details of change template

//Enter CLI commands
configure terminal
//Use variables in commands sent

//Optionally iterate through list of interfaces
foreach (@interfaceItem in @ContextNode.Interfaces)
if (@interfaceItem.InterfaceAlias contains ‘sometext’)
//Send these CLI commands
interface @interfaceItem.InterfaceDescription
//Add other CLI commands here
//Do something else

Small Brother (NCG) -v- Big Brother (NCM)

There is a growing trend amongst manufacturers of expensive network utilities to also provide a free version.  These free tools have no time limitations, and they contain all the features that a small network needs.  One benefit is that you can try before your buy.  I also like the idea of big companies in effect subsidising their poorer brethren.  But most of all, I like this new breed of free utilities because they help me learn more about computer networks.

For small networks the free Network Config Generator (CG) has all the features that you require – thank you very much SolarWinds.  However, if your network grows, or you have a complex network right now, then consider the extra features of the main man, namely the Orion Network Configuration Manager (NCM).  Lookout for a copy of this and other free utilities as you download the free Network Config Generator.

Possible Problems Using the Server Config Generator

Throughout this appraisal I keep stressing that CG is a free tool, great for getting you started, it still requires a machine with the SNMP service running, and an active ‘Public’ community.  If you have any problems then sign up for SolarWinds Thwack forum, that’s where the experts on Config Generator (and Orion) hang out and they will answer your questions.

For ‘Cisco Kids’, those with CCNA qualifications, they may face different problems, namely that CG only monitors one device at a time, and to them I say, ‘try the big brother Orion Network Configuration Manager’.

Here are my reviews of tried and tested applications to monitor your network.  Most of these utilities are free, while the others are the full program, but time restricted.  SolarWinds are a great source of free specialist tools.  A constant theme is a free gadget for testing, backed-up with a comprehensive suite for programs for larger organizations.  I like the way that big companies subsidise their smaller brethren… until they become large companies!
