PRTG: An easy-to-use Cisco monitoring tool –
at no extra charge

How does Cisco Monitoring with PRTG work?


iWhat is a sensor?

In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Specially designed sensors for a better look inside your Cisco network

Cisco offers powerful solutions in several areas, from network management and unified communication to routing and switching management. By professionally monitoring Cisco-related parameters, you can exhaust all the possibilities – at no extra charge. Remaining true to our “all-inclusive” philosophy, we have also provided access to all Cisco sensors in the PRTG freeware version. Simply activate the sensors and get started with monitoring Cisco devices.

Effortlessly obtain an overview of the system status, find out all there is to know about a device status and your network hardware like routers or switches, gain valuable information on traffic, connections, and users, and get help making service management decisions. With PRTG, you’ll guarantee system health, high performance, connection stability, and application security in your Cisco networks.

Part of the Cisco ecosystem, Paessler has developed sensors especially for Cisco devices. Additional sensors use Cisco-specific NetFlow technology for traffic monitoring. From ADSL to VPN connections, all the way to Voice over IP applications: PRTG ensures the quality of your service.

With PRTG, everyone can work with peace of mind.

Cisco performance monitoring:
Keep an eye on routers, switches, and ports

Cisco router monitoring

Cisco routers are extremely stable and offer high levels of security. No wonder so many sysadmins like to use Cisco routers for their networks. These devices are primarily used at companies. With PRTG, you can easily monitor your Cisco routers with NetFlow or SNMP.

Cisco switch monitoring

Also extremely popular: Cisco switches. Switches, however, are often the bottlenecks in a network. If a Cisco switch malfunctions or becomes overloaded, the entire network can suffer. Professional switch monitoring is therefore a vital part of network monitoring. If problems arise, you’ll be alerted automatically.

Cisco port monitoring

Many sysadmins search for a monitoring tool just for their Cisco ports. They want to find out if their Cisco ports are working properly, as well as determine how much (and which) traffic is flowing through the ports. PRTG uses NetFlow, SNMP, and packet sniffers to monitor open and closed Cisco ports.

Cisco QoS at a glance

Looking to monitor the quality of service of your Cisco devices? PRTG has developed a sensor that can do so. The SNMP Cisco CB QoS Sensor uses data from Cisco’s Class-Based Quality of Service.

Cisco IP SLA monitoring

If you have a Cisco device that supports IP SLA, then you can use a preconfigured PRTG sensor for your Cisco IP SLA monitoring. As a result, you can monitor your service level agreements and in turn, your quality of service.

Cisco Monitoring: Why PRTG is the right choice!










i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

1. Quality enhanced by membership in a developer network

Member of the Cisco Developer Network, PRTG provides custom-fit sensors for your Cisco network so you can always be on the safe side.

2. No additional costs for Cisco sensors

Many software companies charge additional fees for Cisco sensors. But thanks to our “all-inclusive” philosophy, you can use any sensors you please, even in the freeware version.

3. Easy VoIP benchmarking

Because they are especially prone to data delays and losses, certain parameters are pre-calculated right from the analysis stage (e.g. ICPIF, MOS). This makes it possible for benchmarking to be performed directly, without additional calculations.

4. Complete quality assurance monitoring

By merging all relevant parameters in just a few sensors, you can easily measure the service quality of your Cisco network and use your findings to make sound decisions.

5. High-performance monitoring via SNMP

Using SNMP technology (if possible and if it makes sense to do so), parameters can be gathered such as statistics on CPU usage and the ADSL connections of your Cisco router under minimal bandwidth consumption.

6. Overview of all IPsec VPN connections

For those Cisco devices with Adaptive Security Appliance (ASA), you get an easy-to-read overview of traffic, users, and IPsec-secured VPN connections. Which users are online and offline? Finding out is a cinch with the PRTG sensors.

7. Quick creation of multiple sensors for VPN connections

By activating the ASA VPN sensors, you can quickly set up additional VPN connections for monitoring. This frees you up from having to create a separate sensor for each individual connection.

8. System health at a glance

With PRTG you get a clear and reliable overview of all necessary values, including temperature, CPU load, power supply, and available memory.

9. Perfect compatibility with Cisco NetFlow technology

Six sensors help high-traffic networks monitor their data traffic and ensure high network performance. The sensors, both in their standard and customizable versions, are compatible with NetFlow protocols IPFIX, NetFlow 9, and NetFlow 5.

10. Automatic notifications

Should an error occur or one of your self-defined thresholds be exceeded, you’ll be notified immediately, wherever you happen to be.

11. Automation for a lighter workload

With the sensors and notifications of PRTG, you no longer need to take the time to check each and every device manually.

12. Better network security

Thanks to our Cisco-specific sensors and extremely clear-cut monitoring, you’ll be quicker to spot security loopholes in your Cisco devices.

This is how Cisco Monitoring with PRTG works

Simple Network Management Protocol (SNMP) is the easiest way to monitor your network. Network and CPU loads are minimal; an analysis with regard to protocol or an IP address however is impossible. We use this protocol whenever we can to enjoy the most efficient of monitoring.

NetFlow is a Cisco technology in which bandwidth usage is determined within a device and collectively transmitted to PRTG. Bandwidth consumption, therefore, is minimized. NetFlow offers a higher degree of detail (e.g. per network protocol/IP address) than SNMP, and because of its low consumption is ideal for cisco networks with a large amount of traffic.


iBandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps). It refers to the?transmission capacity of a connection and is an important factor when determining the quality and speed of a network.

Cisco network monitoring tools: 3 short comparisons

Comparison I:
PRTG vs. Cisco Prime

Cisco offers its own monitoring software called “Cisco Prime Network Analysis Module.” But many sysadmins manage IT infrastructures that have developed over several years and contain hardware from a variety of manufacturers. PRTG incorporates the technology you’ll need to monitor the hardware of several different manufacturers. All monitoring data comes together on an easy-to-read dashboard.

Comparison II:
PRTG vs. Nagios

A variety of open-source software (such as Nagios) is available for Cisco monitoring (see in-depth comparison). Open-source software is usually cheaper in the short run. But its setup can be considerably more difficult. And more often than not, open-source software lacks important functions that you’ll have to integrate later. PRTG is easy to set up and all-inclusive, and even comes with a fantastic technical support team who usually answer your inquiries within 24 hours on weekdays.

Comparison III:
PRTG vs. SolarWinds

You can also choose from proprietary software to monitor your Cisco hardware. This software includes large, comprehensive tools such as SolarWinds (to in-depth comparison). The advantage of PRTG – from our point of view: PRTG licenses are transparent and straightforward, and include Cisco monitoring. What’s more, specialized tools such as Zabbix are only isolated solutions.
