Best Cisco Monitoring Tools for Network Performance and Routers

By Staff Contributor on November 28, 2019

Cisco is one of the largest networking companies in the world, providing a huge number of products and services. Most businesses could be assumed to have at least some Cisco equipment forming part of their network, and in some cases an entire network infrastructure might be comprised of Cisco equipment. This includes routers, switches, and access points.

As a business expands, monitoring the network and all connected devices becomes increasingly important. Cisco network monitoring tools help network administrators make sure equipment is running smoothly and facilitate streamlined troubleshooting. In this article, we’ll look at why you should be monitoring your Cisco devices, common protocols used for monitoring, and the best Cisco monitoring tools available, including in-depth reviews of the best solutions on the market today and reasons I chose my top pick, SolarWinds® Network Performance Monitor.

Why Is Monitoring Cisco Devices Important?

Businesses undertake network monitoring for a range of reasons. Primary among them are to ensure optimal performance, to detect security threats, to facilitate troubleshooting, and to inform capacity planning.

  • Performance: When you have several devices on your network, small changes in the performance of one device can majorly affect the performance of others. These issues can radically affect how efficient and productive your employees are. Slow networks can result in shared devices and folders being sluggish to load, and employees might find centralized databases lag if there’s a problem with servers or storage devices.
  • Security: One of the most crucial parts of network administration is keeping your network and enterprise data secure. Undetected breaches could rapidly spread through your systems, wreaking havoc on your network, and data leaks could cause major losses to your company in terms of both reputation and money. Monitoring can be vital in detecting security threats before they take over your entire network. Network monitoring tools can tell you if a device crashes or stops responding (which could be a sign of something like a DDoS attack). They can also tell you if a storage device is rapidly becoming full, which could indicate a malicious attack or problem with event logs.
  • Troubleshooting: With a network monitor in place, if a problem comes up with one of your devices, users, or connections, you can quickly see where the problem is, and when it occurred. As a result, you’ll find you can troubleshoot the issue much faster. Using high-quality Cisco troubleshooting tools means your end users will be less significantly affected, and fewer productivity losses will result.
  • Capacity planning: Monitoring your networks enables you to better engage in capacity planning, as you can track which devices are running low on space or are slowing down in performance. On many network monitors, you can set up alerts to tell you when a device is reaching capacity, and some will even give you capacity planning suggestions to ensure your network is always running at its best.

Protocols for Cisco Network Performance Monitoring

Several protocols are used to monitor Cisco devices. Having an idea of how each of these protocols works is crucial to understanding how to manage Cisco routers and other devices, and ultimately getting the most out of your monitoring tools.

  • HTTP/HTTPS (Hypertext Transfer Protocol/Hypertext Transfer Protocol Secure): This is a protocol for transferring hypermedia (text and hyperlinks, audio, video, etc.). HTTP/HTTPS helps facilitate communications between clients and servers.
  • SNMP (Simple Network Management Protocol): This is used for collecting information about devices on a network and modifying the information to change device behavior, such as switching a device on or off. Cisco SNMP software is common in many enterprises.
  • ICMP (Internet Control Message Protocol): ICMP is used to generate error-reporting messages for devices such as routers.
  • CDP (Cisco Discovery Protocol): This proprietary protocol developed by Cisco is used to share information between directly connected Cisco equipment.
  • Syslog: This is a standard protocol used to send system log messages to a logging server.
  • NetFlow: NetFlow is also Cisco-specific. It’s used for looking at IP network traffic as it goes through different interfaces in the network. To look at NetFlow, you’ll need a compatible Cisco network traffic monitoring tool.
  • IP SLA (Internet Protocol Service Level Agreement): This proprietary part of Cisco IOS allows network performance information to be collected in real time.
  • Telnet and SSH: SSH (Secure Shell) is the only protocol capable of accessing devices on the network through the internet. Telnet is also used for remote access but isn’t secure like SSH.
  • RADIUS (Remote Access Dial-In User Service): This is used for logging and authenticating dial-up connections to a network.
  • TACACS+ (Terminal Access Controller Access Control Service Plus): Cisco developed this protocol to address weaknesses in RADIUS. Administrators use it to access devices such as routers and switches.

Cisco Network Performance Monitoring Tools

When looking to manage Cisco routers and networks, you’ll want to consider your monitoring goals. You may want to monitor all your network devices, or you might opt for more targeted monitoring of critical devices. When it comes to Cisco network monitoring tools, lot of options are on the market, and I’ve compiled a list of the best.

Perhaps not surprisingly, given the company’s reputation for standout network management software, my top three picks are from SolarWinds. In addition to premier paid software, I’ve also included a couple of free tools to suit smaller organizations or those with smaller budgets. Whichever tool you end up choosing, it should be capable of monitoring all your Cisco network devices, producing network alerts, and facilitating reporting.

  1. SolarWinds Network Performance Monitor

 SolarWinds Network Performance Monitor (NPM) is my top choice when it comes to Cisco network monitoring tools, since its comprehensive set of features make it stand out from competitors.

Network Performance Monitor

First, NPM can automatically detect and identify all Cisco devices on your network through SNMP monitoring. If you have devices from multiple vendors, you can also use NPM to discover them provided they have SNMP enabled.

The tool also provides a range of customizable charts and can display network performance, device availability, and faults to aid you in troubleshooting. If you struggle to manage and monitor a large, constantly changing network, NPM can dynamically monitor your devices and update your network topology in real time. You can also create network topology maps to see your entire network in one picture, including device performance and connectivity.

SolarWinds NPM allows you to monitor your Cisco Application-Centric Infrastructure and check whether your SDN environment is functioning correctly from a single, centralized monitoring tool. This means you don’t need different monitors for each part of your network.

Aside from these Cisco-specific network monitoring tools, NPM includes a wide range of general network monitoring features. For example, the NetPath link analysis tool allows you to see network connections hop by hop and analyze each stage of the path, which results in faster troubleshooting. The PerfStack feature, meanwhile, shows you different performance metrics to compare and contrast in graph form and determine which performance issues affect others.

In sum, NPM is an extremely high-quality network performance monitoring tool and includes specific features for handling Cisco devices and environments. You can try a fully functional version free for 30 days.

  1. SolarWinds Network Configuration Manager

In contrast to SolarWinds NPM, Network Configuration Monitor (NCM) is more focused on setting up and configuring your networks. Its monitoring and proprietary Network Insight tools made specifically for Cisco network devices make it a great piece of Cisco management software.

Network Configuration Monitor

NCM is designed to manage rapid and complex changes across large networks, and it offers high levels of automation. It can deploy standardized configs across the entire network, including out-of-process changes and configuration for audit purposes. This reduces the amount of time you need to spend on repetitive network management tasks and helps maintain service levels and meet compliance requirements.

For Cisco devices, NCM includes Network Insight for Cisco ASA traffic monitoring, which allows you to back up and store your config files and work with access control lists. It also provides Cisco Nexus switch monitoring. Switches can have huge numbers of interfaces, making switch monitoring a major challenge without the appropriate tools. SolarWinds NCM allows you to view the config details for each interface, helping you ensure service availability. In addition, it shows detailed information about virtual port channels, so you can maintain an overall picture of relationships between them, and allows you to check for redundancies, status, and any interface problems.

NCM easily integrates with NPM, so you can use both tools together for deeper network insights. As with NPM, NCM is also available as a fully functional free trial for 30 days.

  1. SolarWinds NetFlow Traffic Analyzer

NetFlow Traffic Analyzer 1

SolarWinds NetFlow Traffic Analyzer (NTA) is more lightweight than either NPM or NCM and can be used for more specific network traffic analysis and monitoring without the features included in the other tools from SolarWinds. However, it can integrate with NPM and NCM. Used together, the three tools provide a robust and comprehensive network monitoring, configuration, and analysis package. 

NTA analyzes bandwidth and network traffic, and works with Cisco NetFlow, Juniper J-Flow, sFlow, Huawei NetStream, and IPFIX. It allows you to identify which applications and devices are consuming the most bandwidth, so you can check those devices for performance issues or reconfigure your network if necessary. It readily supports all Cisco devices, so you can get a clear picture of your entire Cisco environment or a combination of devices from different vendors.

With NTA you can set up alerts to let you know if there’s an unusual change in network traffic, so you can fix the problem before it affects your end users. The tool’s NetFlow software also shows you historical data, so you can identify peaks and troughs in bandwidth usage, and shape and allocate bandwidth as necessary to keep performance steady for your organization. Like NPM, NTA includes the PerfStack feature, which enables you to compare network performance metrics in a visual form. Viewing each metric next to the others can help you to more quickly pinpoint and troubleshoot issues.

SolarWinds offers a 30-day free trial of NTA. If you are working with a large enterprise, using NPM or a combination of all three is your best option, as NTA is more lightweight than the other two but offers complementary features. However, if you’re in a smaller enterprise, NTA might be enough on its own.

  1. Paessler PRTG Network Monitor

Paessler PRTG Network Monitor-4

Paessler is another big player on the market offering high quality when it comes to Cisco network monitoring tools.
