CloudVision Wi-Fi can automatically capture packet traces when an AP detects a connectivity failure. The captured packet traces can be accessed and downloaded from the CloudVision Wi-Fi GUI under Connection Logs.
This feature is useful for troubleshooting random client connectivity issues that last for a short duration and hence make it difficult for the administrator to capture the trace. For example incorrect password, DHCP and DNS issues
- Administrator or higher access to CloudVision Wi-Fi/Wireless Manager.
- On CloudVision Wi-Fi, navigate to Troubleshoot > Packet trace > Auto Packet Trace
- Click on Auto Packet Trace and select one or more SSIDs for auto packet trace.
Note: Automatically captured packet traces are not shown on the same screen. See Client Connection Logs for a specific client to view the list of automatically captured packet trace files. Only packet traces captured in the last 30 minutes are available.
Enabling this feature via Wireless Manager
- Access Wireless Manager and Navigate to Configuration > Device configuration > SSID profile. Click on Add new Wi-Fi profile or edit an existing SSID.
- Scroll down to the Troubleshooting section and enable the checkbox for Enabled Automatic Packet Capture.
Example 1: Successful connection
Example 2: User enters incorrect PSK
Example 3: DHCP IP address assignment issue
- This option is only supported for 802.11ac AP platforms and upward.
- A maximum of five packet traces is retained in the system for each client.
- The trace file names are system-defined and based on the MAC addresses of the client, the AP BSSID, and the timestamp of the packet capture session.
