Switch traffic monitoring: 3 types of sensors to help you get started

1. SNMP sensors

PRTG comes with preconfigured SNMP sensors for the switches of manufacturers such as HP, Cisco, and Dell.

2. Packet Sniffer Sensor

The Packet Sniffer Sensor monitors traffic, and filters by IP addresses, protocols, and data types.

3. NetFlow/sFlow/jFlow sensors

Thanks to the PRTG NetFlow sensors, you can also monitor the traffic and bandwidth of switches from manufacturers such as Cisco and Juniper.


Switch monitoring: 3 sensors for monitoring hardware

 i How PRTG defines sensors

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.

With PRTG, you’ll immediately see if a port is open. As a result, you can close gateways and enhance the security of your network.

PRTG optimizes bandwidth consumption

Which applications are responsible for the most traffic? Where do bottlenecks tend to arise? Network diagnostics with PRTG provides quick answers to these and other questions, and thus boosts the efficiency of your network!

 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.

daniel elsner

Practical tip: “Hey Daniel, do you have any port monitoring tips up your sleeve?”

“With routers, switches, hubs, and bridges, your network has a great deal of ports which potentially need to be monitored. I would therefore recommend creating at least one active sensor per port on each of your central network components. By doing so, you should be able to monitor all of a network device’s active ports, as well as its CPU and RAM. On the other hand, for those network components which are not so vital, it is often sufficient to use paused sensors instead of actively monitoring every port.”

PRTG is compatible with
a variety of switch manufacturers

A lot to choose from

Most router and server manufacturers like Linksys, Netgear, or Yamaha are also in the business of switches. In fact, the number of available switches is constantly on the rise. We will therefore only cover a few of the products made by some of the main manufacturers. Status as of 2017.

Mixing manufacturers

Many administrators use a variety of different switches from a variety of different manufacturers. As a result, they often find it difficult to find monitoring software that can monitor all their switches at the same time. That’s where PRTG comes in: our switch monitoring software is compatible with nearly every major switch manufacturer.


Common switch manufacturers



Cisco makes a variety of different switches for companies and organizations, including Cisco Catalyst series switches, Cisco Industrial Ethernet series switches, and Cisco Nexus switches. Learn more about Cisco monitoring with PRTG here.


HP offers a variety of switches that can be used for both large or small data centers. An example: the HP Procurve switch. PRTG comes with several preconfigured sensors for HP products.


Huawei also makes Ethernet switches for larger corporations. Some of these include campus switches (S12700 series), data center switches (CloudEngine series), and SME switches for smaller companies.


Juniper offers two types of switches: EX switches and QFX switches. Administrators are often looking for the best way to monitor these switches.


Dell offers Dell Networking X-Series switches to company networks which support SNMP. PRTG comes with various preconfigured SNMP sensors for Dell. Learn more about Dell monitoring here.


Arista makes layer 3 switches. Compared to Cisco, Arista is a smaller manufacturer. Nevertheless, its switches are used by many companies and organizations.

Switch port monitoring with PRTG

Security: Keeping an eye on open switch ports

When monitoring switch ports, administrators are up against some major challenges. They must be able to continually check for open and closed ports, as well as potentially dangerous open switch ports. With PRTG, you'll keep constant track of your ports – and automatically receive an alarm if something goes awry.

An overview of switch port capacities

If a switch is stretched beyond its capacities, then it is sure to break down. Such a situation is both frustrating and unnecessary, for with PRTG, you are quickly informed of impending overloads and can upgrade or relieve the switch accordingly. Learn more about port monitoring with PRTG here.

 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.

Ping monitoring

PRTG uses ping to check the availability of your network devices in real time, and promptly reports errors so you can take action at once. The Auto Discovery feature makes setup both quick and easy. Learn more about ping monitoring here.

 i Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the computer that was pinged back to the originating computer.
