The routerconfigs plugin is designed to act in conjunction with the Cacti servers tftp server to receive backups from your router devices. It also provides the ability to view and diff those router configurations as they change over time. It is designed primarily for Cisco device types, but may work with other device types.
NOTE: Whilst this plugin is actively maintained by the Cacti Group, it is a community plugin that primarily receives contributions from the Cacti community. The Cacti Group has recently updated the plugin functionality to support the vast majority of devices on Cacti 1.x and beyond. Help from the community on functionality changes, compatibility and the like are always welcome.
Some HP devices are returning ANSI codes as part of their output, rather than normal ASCII output given by most other devices. These devices currently will not work with Router Configs.
To verify this, use the debug buffer option to capture all input/output used by routerconfigs. If the output does not look as you would see when running these commands manually, the chances are the device is experiencing this issue. Please feel free to post an issue on the GitHub site for verification should you require assistance.
Just like any other Cacti plugin, untar the package to the Cacti plugins directory, rename the directory to 'routerconfigs', and then from Cacti's Plugin Management interface, Install and Enable the plugin.
This plugin requires a TFTP server on the Cacti server (see below for an example under CentOS 6)
There are a few options in Cacti you will need to change to then get the plugin up and running. They are located under Settings > Router Configs
| Setting | Description |
|---|---|
| TFTP Server IP | The IP Address of the Cacti server given to the routers |
| TFTP Backup Directory Path | The directory that your TFTP server stores its files |
| Archive Path | The directory to copy the configuration to |
With those global settings in place, you will then need to - Create a device type - Create an authentication account - Create a device
On other operating systems, or for CentOS 7, you will have to find equivalent instructions.
Bug and feature enhancements for the routerconfigs plugin are handled in GitHub. If you find a first search the Cacti forums for a solution before creating an issue in GitHub.
For CentOS 6, just run these commands:
yum install tftp-serverThe edit the tftp startup script (/etc/xinetd.d/tftp) to change the server arguments, I used this line:
server_args= -c -s /home/configs/backupsYou will need to create this folder (or whatever folder you specify) and give the apache server and the tftp server permissions to access it
I have provided a copy of this file for you. Then we just need to turn on the tftp server so do this.
chkconfig xinetd on
service xinetd startCopyright (c) 2004-2025 - The Cacti Group, Inc.
