Introduction to AP Client Packet Capture
The AP Client Packet Capture feature allows the packets on an AP to be captured for wireless client troubleshooting. The packet capture operation is performed on the AP by the radio drivers on the current channel on which it is operational, based on the specified packet capture filter. All the packets that are captured for a specific client are uploaded to a file in the FTP server. This file can be opened in Wireshark for packet inspection.
Limitations for AP Client Packet Capture
The packet capture task can be performed for only one client at a time per site.
Packet capture can be started on a specific AP or a set of APs using static mode. It can be started or stopped for the same client on different APs, when the capture is in progress.
When packet capture is started in auto mode, system automatically selects the set of nearby APs to start packet capture for a specific client. In this mode, you cannot start or stop packet capture on individual APs. Use the stop all command to stop the packet capture when it is started in auto-mode.
After the SSO is complete, the packet capture action will not continue after a switchover.
