Automatic Packet Capture for Client Failures

You can automatically capture a packet trace when client connectivity failures are detected. You can then analyze these packet traces in the Client Connection Logs in Discover to troubleshoot connectivity issues with your devices. For more information, see Capture Packet Trace.

Download Packet Trace link will appear in the logs when a failure occurs. Five of the latest packet traces are stored for each client and these traces are retained for a maximum of seven days.

You can enable automatic packet capture in Discover:

  1. From Discover, select Configure > Troubleshoot > Packet Trace.
  2. Click Auto Packet Trace.
  3. Select the SSIDs that will perform an automatic packet trace after a client connectivity failure.
