Switch Metrics

Get familiar with the metrics that you can use to monitor your switches and address issues with excess APs, over-allocated PoE, low uptime, and more.

Use the metrics on the Switches page to track the switch performance against certain compliance parameters.

To view switch metrics, click Switches on the left navigation pane on the Mist portal. Metrics for which there is no data appear grey (usually because the feature has not been configured).

Here's a list of the switch metrics you can track:

  • Switch-AP Affinity—This indicator shows the weighted percentage of the switches for which the number of APs connected exceeds the threshold configured. By default, the Switch-AP Affinity threshold is set to 12 APs per switch. You can modify the threshold value to be used in the Switch-AP Affinity metric calculation. To configure the AP threshold, click the Switch-AP Affinity indicator, and then click the hamburger icon on the right of the Switch-AP Affinity section. This metric helps you quickly identify overloaded switches and balance AP distribution to improve network reliability. Select the Topology view at the top of the page for an interactive display that lets you click a site and then a switch to view the APs connected to that switch.

  • PoE Compliance—This indicator shows the percentage of APs that have the required 802.3at power. PoE compliance is impacted when the APs draw more power from the switch than what is allocated.

  • VLANs—This indicator shows the percentage of APs for which all the wired VLANs are active. Click this indicator to view the list of switches and APs that have inactive or missing VLANs, along with the port information.

  • Version Compliance— This indicator shows the percentage of switches that have the same Junos software version (per switch model). To achieve 100 percent version compliance, you must ensure that all the switches in your site run the same Junos version per switch model.

  • Switch Uptime—This indicator shows the percentage of time a switch was up during the past seven days, averaged across all switches. Click this indicator to view the list of switches that had less than 100 percent uptime during the past 7 days.

  • Config Success—This indicator shows the percentage of switches that are currently in a configuration success state, providing quick visibility into overall network health. If the success rate is below 100 percentage, click this indicator to view the switches that are in a configuration failed state. A switch is marked as configuration failed when its most recent configuration event (within the past 7 days) has failed.

  • Switchport Usage—This indicator helps you quickly assess the availability of switch ports. It displays percentage of ports that are currently in use. Hover over this indicator to view a breakdown of total, active, and inactive port counts. If the switch port usage is 90 percentage or higher, the indicator turns red to indicate that the number of ports available for use is low.

  • Potential Anomalies—This indicator displays the percentage of switches that currently have no potential anomalies detected by Marvis.

    • If none of the switches have potential anomalies, the percentage is 100%.

    • If the switches have potential anomalies, the value decreases in proportion to how many are affected. For example, if a site has 10 switches and 2 of them have anomalies, the percentage is 80%.

    If the percentage is less than 100%, you can click the indicator to view the switches with anomalies. Switches with potential anomalies are listed with a Troubleshoot button. Clicking the Troubleshoot button launches the conversational assistant with a pre-filled prompt such as “Troubleshoot <device> for last 7 days”, enabling you to view the detected anomalies without having to manually initiate troubleshooting.

You can click each of the switch metric indicators to get a filtered view and quickly access each device dashboard.

The Switches tab is where you can get all the wired health metrics. Switches in grey are being discovered, while green indicates that the switch is online and fully managed by the Juniper Mist cloud. The metrics at the top provide a high-level sense of how the switches below are doing.

Non-Juniper switches are still accounted for and can get wired visibility via LLDP by connecting a Juniper access point and MARVIS. These health metrics include switch AP affinity, meaning do you have too many APs connected to a switch? PoE compliance, are the APs getting enough power? Other metrics shown include VLANs, version compliance, and switch uptime. Aside from the list view, you can also choose to see the switches in a topology or location view.

The topology view is an interactive way to see all your switches and the APs connected to them. The location view shows a map of where all the switches are located. Whether you have Juniper EXs or third-party platforms, Wired Assurance delivers the wired visibility and health metrics to give you a good pulse on how the network is doing.
