Powerful troubleshooting at your fingertips

New tools in Meraki MS switches enable you to perform troubleshooting tasks such as Ethernet cable testing, searching through event logs, and live packet captures right from the Meraki dashboard.

In our last post, we talked about how easy it is to optimize VoIP with 3 easy clicks on Meraki’s MS Cloud Managed Switches. While we make configuration a breeze, sometimes as a network administrator, you want to really dive into the details to figure out what’s happening on your network. With the Meraki MS Cloud Managed Switches, we make troubleshooting a snap.

Event Logs

If you ever wanted to know all the changes that have happened on your switch network, our event log lets you view all the changes in your virtual stack to see events such as STP enabled/disabled, ports enabled/disabled, Live Tools tests that were run such as cable tests, and more. This gives you a historical view that’s useful if you want to correlate an event such as a network outage with configuration changes on your switches. You can find Event Log under Monitor>Event Log.

For those of you who aren’t familiar with the concept of the virtual stack, this is an industry-first technology that provides centralized management of up to 10,000 switch ports. Unlike traditional stacking, virtually stacked switches can be in different physical locations, simplifying large scale and distributed deployments.

While our event log provides an easy way to see historical information, sometimes you need to do some live troubleshooting, and this is where the power of our Live Tools comes in.

Live Tools – Cable Test and Packet Capture

When it’s time for a network refresh, oftentimes you leave the existing wiring infrastructure in place and just replace your switches. This means that the quality of an Ethernet cable is unknown, and this could lead to hours of frustration when a user complains that their connection is down. You could spend hours debugging a healthy switch when the problem is simply a cabling issue. With our integrated cable test, you can quickly and easily see if the cabling is an issue or if it’s something more serious. You don’t need to be on site to run this test, and the end client doesn’t even need to be plugged in for it to work! You can find this useful tool in the Meraki dashboard under Monitor > Switches.

Event logs and cable tests are great for troubleshooting common networking issues, but what if you need to really dive into the bits and bytes of a packet? The MS Switches now have a powerful packet capture tool which lets you quickly and easily capture packets on one port or multiple ports for further analysis. You can even download the output as a PCAP file for analysis using Wireshark, a popular free network protocol analyzer. If you’ve ever tried capturing packets before, you know what a pain it is: you have to set up port mirroring, assign a new VLAN, and load specialized software on your laptop. With our packet capture tool, we make it one step and you can do it remotely from the comfort of your office or home! You can find the tool under Monitor > Packet capture.

If you do not see these features on your dashboard, you may require a firmware upgrade. Please contact [email protected] to schedule the upgrade.

Don’t forget to check out our new features under the Help > New features page regularly. We are constantly adding more exciting features and we’re expanding and improving existing features!
