pcap dispatch trace

Summary/usage

pcap dispatch trace [on|off] [max <nn>] [file <name>] [status]
          [buffer-trace <input-node-name> <nn>].

Description

This command is used to start or stop pcap dispatch trace capture, or show the capture status.

This command has the following optional parameters:

on|off - Used to start or stop capture.
max <nn> - Depth of local buffer. Once 'nn' number of packets have been received, buffer is flushed to file. Once another 'nn' number of packets have been received, buffer is flushed to file, overwriting previous write. If not entered, value defaults to 100. Can only be updated if packet capture is off.
file <name> - Used to specify the output filename. The file will be placed in the '/tmp' directory, so only the filename is supported. Directory should not be entered. If file already exists, file will be overwritten. If no filename is provided, '/tmp/vpe.pcap' will be used. Can only be updated if packet capture is off.
status - Displays the current status and configured attributes associated with a packet capture. If packet capture is in progress, 'status' also will return the number of packets currently in the local buffer. All additional attributes entered on command line with 'status' will be ignored and not applied.

Example usage

Example of how to display the status of capture when off: vpp# pcap dispatch trace status

max is 100, for any interface to file /tmp/vpe.pcap
pcap dispatch capture is off...

Example of how to start a dispatch trace capture: vpp# pcap dispatch trace on max 35 file dispatchTrace.pcap

pcap dispatch capture on...

Example of how to start a dispatch trace capture with buffer tracing vpp# pcap dispatch trace on max 10000 file dispatchTrace.pcap buffer-trace dpdk-input 1000

pcap dispatch capture on...

Example of how to display the status of a tx packet capture in progress: vpp# pcap tx trace status

max is 35, dispatch trace to file /tmp/vppTest.pcap
pcap tx capture is on: 20 of 35 pkts...

Example of how to stop a tx packet capture: vpp# vppctl pcap dispatch trace off

captured 21 pkts...
saved to /tmp/dispatchTrace.pcap...
