CloudVision WiFi can automatically capture packet traces when an AP detects a connectivity failure. The captured packet traces can be accessed and downloaded from the CloudVision WiFi 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 WiFi/Wireless Manager.
- On CloudVision WiFi, 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 WiFi 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.
