Syntax

# debug capture voip physical {clear|cyclic-buffer|eth-lan|get_last_capture|insert-pad|show|start|stop|target}
# debug capture voip physical target {ftp|tftp|usb}
# debug capture voip physical get_last_capture <TFTP/FTP Server IP Address>
■ To start a capture: 
# debug capture voip physical start
■ To stop a capture: 
# debug capture voip physical stop {<TFTP/FTP server IP Address>|usb}

Command

Description
clear

Deletes captured files from the device's RAM.
cyclic-buffer

Continuously captures packets in a cyclical buffer.
Packets are continuously captured until the Stop command is entered.
eth-lan

Captures LAN frames.
get_last_capture

Retrieves the last captured PCAP file sent to a specified TFTP/FTP server IP address.

Note: The file is saved to the device's memory (not flash) and is erased after a device reset.
insert-pad

Before running this command, the debug capture must be started.

Inserts a PAD packet. A marked packet is shown with black background regardless of the configured coloring rules. Benefit: A marked packet can easily be located later when analyzing in a large capture file.

stop

Stops the capture and sends the capture file to the specified target. The capture file is named:
"debug-capture-voip-<timestamp>.pcap"

Examples

■ Starting a physical VoIP debug capture: 
# debug capture voip physical eth-lan
# debug capture voip physical start
■ Retrieving the latest capture (PCAP file) saved on a specified server. 
# debug capture voip physical get_last_capture 10.15.7.99
■ Specifying USB as the destination to which to send the PCAP file: 
# debug capture voip physical target usb
