Using the MS Live Tools
One of the major benefits of using the Cisco Meraki Dashboard is an admin's ability to monitor the status of any network device, without the use of 3rd party management tools or solutions. A device's status page contains a lot of useful, up-to-date information about the device and connected hosts, including a number of "Live Tools" that can be used to see current information about the device. Live Tools include real-time usage statistics, client visibility, ping, throughput, and the ability to blink the LEDs on a switch. This article details the features and functions of the Live Tools available for the MS switch series.
Note: The information generated via the Live Tools will only be accurate if the device is online and communicating with Dashboard.

Accessing the MS Live Tools
The MS Live Tools provide information relevant to a specific switch, therefore the Live Tools are available on a switch's overview page. The following instructions describe how to reach a switch's overview page and find the Live Tools for that device:
- In Dashboard, navigate to Switch > Monitor > Switches.
- Select the switch you would like to use (by clicking on the switch's name, not the checkbox).
- Click on the Tools tab, which should look like the image below:
Using the MS Live Tools
Each of the Live Tools can be used to perform remote troubleshooting on the device. This section details each tool that is available, as well as some use cases for each.
Cable Test Live Tool
This tool allows an admin to test the wire connected to ports on the switch. In the box, enter a port number, multiple port numbers (separated by commas), or a range of port numbers (e.g. 1-24). If there is a cable plugged into the port(s), this test will determine the link speed/duplex, cable length, and twisted pair status of cable(s) connected. This test can be a quick way to determine if a faulty cable needs to be replaced, therefore narrowing down possible causes of a network issue.

This tool allows an admin to quickly disable and re-enable a switch port, multiple port numbers (separated by commas), or a range of port numbers (e.g. 1-24). PoE powered devices will be temporarily powered down. This can be useful to remotely reboot a connected PoE powered device such as a VoIP phone, or an Access Point.
This table shows MAC addresses that the switch is currently aware of, and which port/VLAN their traffic is being forwarded through. There is also a search bar, which can be used to filter for a specific mapping. If traffic from a particular MAC does not appear to be tagged with the appropriate VLAN, this table can be used to quickly determine if a switch port configuration are misconfigured.
If a client machine has been configured with Wake-on-LAN enabled, an admin can specify that host's MAC address to send a magic packet and wake the host machine. An admin can also specify a VLAN, and broadcast a magic packet out on that VLAN. This tool can be useful in a network environment that utilizes Wake-on-LAN for remote power management.
Ping will initiate a series of ICMP Echo requests to the designated IP or domain name. Based on the responses, it will graph the round trip time (RTT) latency. Click the X to remove a ping test.
- If the MS Switch/Stack is only configured for Layer 2 switching, then pings will be sourced from the MS management interface.
If the MS Switch/Stack has a Layer 3 routing configuration, then pings will be sourced from the Layer 3 interface specified in the drop down.

A MTR test combines ICMP and Traceroute functionalities to perform a more detailed reachability test. This test performs a hop by hop analysis of reachability. This is commonly utilized for identifying potential causes for loss or delays to a destination from the MS' LAN IP. This destination may be a FQDN or IP address.
This tool will determine the approximate throughput between this device and the Cisco Meraki Cloud Controller. To use this tool, click on the play button and wait approximately 10 seconds. The device will send traffic to the cloud controller and report the approximate calculated speed on the tool. This can be used to get a general idea of throughput for upstream traffic from this device, which can be helpful in the event of a suspected bandwidth issue.
Note: Reported speeds may be less than actual speeds, as the test will be affected by other switch behaviors and functions. For a more accurate throughput test between two nodes, please use iperf or another throughput test.

By clicking the run button, this tool will cause all LEDs on this switch to blink. This can be a quick way to identify an unlabeled switch in a rack.
This tool can be used to soft reboot a switch. This tool will temporarily disconnect all clients, so it is advised only to reboot the device during scheduled maintenance hours or in the event of an emergency. Because this reboot is only a soft reboot, it will retain its current configuration upon rebooting.
