Parameters
packet-limit packet-limit: Specifies the maximum number of packets that can be captured by an AP, in the range of 1 to 10000.
Description
Use wlan capture packet-limit to configure the maximum number of packets that can be captured by an AP.
Use undo wlan capture packet-limit to restore the default.
By default, the maximum number of packets that can be captured by an AP is 10000.
You are not allowed to change the maximum number of packets that can be captured by an AP during the WLAN sniffer process.
WLAN sniffer stops when the maximum number is reached.

Description
Use wlan capture file-name to specify the name of the CAP file to which the captured packets are saved.
Use undo wlan capture file-name to restore the default.
By default, the name of the CAP file to which the captured packets are saved is CaptureRecord.
The file has a fixed extension .dmp, which is not configurable.
You are not allowed to change the name of the CAP file during the WLAN sniffer process.

Default level
2: System level
Parameters
ap ap-name: Specifies an AP name, a case-insensitive string of 1 to 32 characters.
radio radio-number: Specifies a radio number.
Description
Use wlan capture start enable the WLAN sniffer function.
By default, the WLAN sniffer function is not configured.
· An auto AP does not support the WLAN sniffer function.
· WLAN sniffer can be enabled for only one radio of an AP.
· To enable WLAN sniffer on a radio, the AP must operate in normal mode and must be in Run state, and the working channel of the radio must be manually specified.
· Disabling the sniffer-enabled radio, deleting the Capture AP, disconnecting the Capture AP from the AC, or disabling WLAN sniffer stops the sniffer operation. The captured packets are saved to the specified CAP file in the default storage medium. The default storage medium varies with device models.
· The working mode of the AP cannot be changed with the work-mode monitor or device-detection enable command when it is capturing packets.
Examples
# Enable the WLAN sniffer function.
