<p>The BNG Blaster is able to log events to the standard output
|
||
|
|
or logging window of the interactive courses interface. Those
|
||
|
|
events could be also logged to files using the argument
|
||
|
|
<code class="docutils literal notranslate"><span class="pre">-L</span> <span class="pre"><file></span></code>.</p>
|
||
|
|
<p>Per default only events classified as <cite>info</cite> or <cite>error</cite> are logged.
|
||
|

<h2>PCAP<a class="headerlink" href="#pcap" title="Permalink to this headline"></a></h2>

<p>You can start the BNG Blaster with the argument <code class="docutils literal notranslate"><span class="pre">-P</span> <span class="pre"><file></span></code>
|
||
|
|
to capture all traffic send and received by the BNG Blaster
|
||
|
|
into a single PCAP file. This file includes all traffic from all
|
||
|
|
interfaces in use with proper meta header to filter by interface
|
||
|
|
names.</p>
|
||
|
|
<p>This helps to verify if traffic is received or how it has received.
|
||
|
|
Some network interfaces drop the most outer VLAN which can be easily
|
||
|
|
verified using the capture file.</p>
