This section describes how to use the controller GUI or CLI to view neighbor statistics for a selected mesh access point. It also describes how to run a link test between the selected mesh access point and its parent.
Step 1 | Choose Wireless > Access Points > All APs to open the All APs page. |
Step 2 | To view neighbor statistics for a specific mesh access point, hover the mouse over the blue drop-down arrow for the desired mesh access point and choose Neighbor Information. The All APs > Access Point Name > Neighbor Info page for the selected mesh access point appears. This page lists the parent, children, and neighbors of the mesh access point. It provides each mesh access point’s name and radio MAC address. |
Step 3 | To perform a link test between the mesh access point and its parent or children, follow these steps:
|
Step 4 | To view the details for any of the mesh access points on this page, follow these steps: |
Step 5 | To view statistics for any of the mesh access points on this page, follow these steps: |
Use these commands to view neighbor statistics for a specific mesh access point using the controller CLI.
