Performing a Link Test
Figure 7-12 Link Test Page
This page shows the results of the CCX link test.
Note If the client and/or controller does not support CCX v4, the controller performs a ping link test
on the client instead, and a much more limited link test page appears.
Step 3 Click OK to exit the link test page.
Using the CLI to Perform a Link Test
Use these commands to run a link test using the CLI.
1. To run a link test, enter this command:
linktest ap_mac
When CCX v4 is enabled on both the controller and the client being tested, information similar to
the following appears:
