Custom alerts and data visualization let you quickly identify and prevent network issues, even in VLAN environments.
Are VLANs a regular cause of headaches for you? That is not surprising, because without proper monitoring, these virtual networks can turn into a source of problems and security risks. That itself should be no surprise, since Virtual Local Area Networks (VLANs) are essential for efficient network segmentation, improved security, and optimized performance. Paessler PRTG offers comprehensive VLAN monitoring capabilities to ensure your network remains secure, efficient, and properly segmented.
Do VLAN misconfigurations keep you up at night? Do you want to make sure all your subnets are as accessible as you want them to be? Then it is time to relax, because PRTG has your back. It quickly spots incorrect VLAN IDs, tags, and switch port assignments. This means you can fix issues before they cause downtime or security breaches. PRTG provides you with all the knowledge you need to check VLAN trunking and routing, ensuring smooth communication across your network.
Tired of unexpected bandwidth bottlenecks? PRTG gives you a clear view of your VLAN traffic patterns and utilization. It monitors both ingress and egress traffic for each VLAN in real-time, showing you exactly where bandwidth is used. Identify bottlenecks quickly and allocate resources effectively. PRTG tracks VLAN performance metrics continuously, helping you make informed decisions about your network infrastructure based on detailed, real-time data.
Worried about VLAN-related security risks? PRTG acts as your vigilant guardian for network segmentation and access control. You can detect the effect of your VLAN access control lists (ACLs) and firewall rules, alerting you to unauthorized access attempts immediately. PRTG ensures proper isolation between different VLANs, maintaining your network segmentation integrity and preventing unauthorized cross-VLAN communication. Keep your network environment secure across all your VLANs with PRTG.
Diagnose network issues by continuously tracking VLAN traffic. Show topology, network configuration, bandwidth, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot VLAN configuration issues and prevent performance problems.

Want to understand your VLAN traffic better? PRTG uses SNMP to check VLAN setups on your switches and routers. It also analyzes NetFlow data to reveal VLAN traffic patterns. Need something specific? Create custom sensors tailored to your unique network needs.
Never miss a critical VLAN event again. Set up alerts for VLAN-specific issues and choose how you want to be notified – email, SMS, or push notifications. PRTG also creates detailed reports on VLAN usage and performance, giving you the data you need to optimize your network and plan for future growth.
As your network expands, PRTG grows with you, offering scalable network monitoring solutions for networks of all sizes. Monitor multiple VLANs across different locations, all from a single interface. As you add new network segments, PRTG adapts to your needs. You'll always have a clear view of your entire network, no matter how large or complex it becomes.
PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!
The SNMP Traffic v2 sensor monitors bandwidth and traffic on a device. It can show the following:
The SNMP RMON sensor monitors traffic on a device using the Remote Monitoring (RMON) standard. It can show the following:
The SNMP Cisco System Health sensor monitors the system health of a Cisco device. It can show the following:
The Port Range sensor monitors a network service by connecting to various TCP/IP ports. It tries to connect to the specified TCP/IP port numbers of a device in succession and waits for the device to accept each request. It can show the following:
See the PRTG Manual for a list of all available sensor types.
Custom alerts and data visualization let you quickly identify and prevent network or performance issues in your VLANs.

VLAN monitoring is the process of tracking and analyzing the performance, traffic, and configuration of Virtual Local Area Networks (VLANs) within a network infrastructure. It involves observing VLAN traffic patterns, ensuring proper VLAN configurations, and maintaining network segmentation and security.
VLAN monitoring is crucial for maintaining an efficient and secure network. It helps network administrators detect configuration errors, optimize bandwidth usage, enhance security through proper segmentation, and quickly troubleshoot VLAN-related issues. Effective VLAN monitoring ensures that your network performs optimally and remains protected against potential security threats.
PRTG uses various technologies to monitor VLANs comprehensively:
PRTG combines these technologies to provide a holistic view of your VLAN performance and health.
Yes, PRTG can monitor multiple VLANs across your entire network infrastructure simultaneously. Its scalable architecture allows you to monitor hundreds or even thousands of VLANs from a single PRTG instance, providing a centralized view of your entire virtual network environment.
VLAN monitoring enhances network security by:
By maintaining strict VLAN boundaries and monitoring inter-VLAN communication, collecting data with PRTG helps you maintain a secure network environment.
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
Paessler PRTG is used by companies of all sizes. Sysadmins love PRTG because it makes their job a whole lot easier.
