Cacti is an excellent tool to use to monitor your company’s bandwidth usage. It is also very simple to add your routers into your cacti configuration. (Note: If you need instructions on installing cacti, see ). Cacti uses the SNMP protocol (Simple Network Management Protocol) to monitor all sorts of devices and has most of the templates that you need to quickly monitor most network and server devices without installing additional plugins. So, let’s begin to Monitor Cisco Routers with Cacti: Enable SNMP on the Cisco Router In order to enable cacti to monitor any device, you must enable SNMP on therouter itself. Nearly every network device will have a method for doing this, Cisco routers in particular require that you have lines similar to the following in your running-config.

SNMP Configuration in Cisco Router: snmp-server community mycommunitystring RO snmp-server location 1234 StreetName Parkway, Mycity, Mystate, other location information. Snmp-server contact Jeff Staten 123-456-7890 Other options are also available that will control which IP Addresses can contact your router with SNMP. Review your router’s documentation for more details specific to your router. Configure Cacti to Monitor a Cisco Router Once your router is configured to allow SNMP monitoring, you can now add your router to cacti so you can graph your routers CPU, load average, and interface statistics. To begin, login to your cacti administration tool using your browser, and under the console tab, choose Devices and then choose the “Add” option from the top right. Adding a Cisco Router to Your Cacti Configuration You will need to populate the fields similar to how I did above in the example: • Description – Give your router’s name here.

• Host Template – Choose the appropriate template for your router. Most routers will work just fine with the “ucd/net SNMP Host” template.

However, if your router is a Cisco, you can use the built in “Cisco Router” template that comes by default with cacti. • Downed Device Detection – Typically any of the available options will work fine. • SNMP Version – You will need to match this to the version that you enabled in your router.
