\subsection{Test 1: IPv4 egress settings work}
|
|
Scenario: simple egress port setting for the IPv4 addresses
|
|
|
|
Step 1: getting correct values for table entries from python:
|
|
|
|
\begin{verbatim}
|
|
>>> int(ipaddress.IPv4Address(u"10.0.0.42"))
|
|
167772202
|
|
>>> int(ipaddress.IPv4Address(u"10.0.0.4"))
|
|
167772164
|
|
>>>
|
|
|
|
\end{verbatim}
|
|
|
|
Step 2: setting table netries
|
|
|
|
\begin{verbatim}
|
|
|
|

|

action_name = TopPipe.realmain.set_egress_port

\end{verbatim}
|
|
|
|
Step 3: setting arp entries
|
|
|
|
\begin{verbatim}
|
|

|
|
|
|
\end{verbatim}
|
|
Step 3: generating test packets, expecting 4 packets to show up on
|
|
enp2s0f0:
|
|
|
|
%\tvb
|
|
\begin{verbatim}
|
|

|
|

|
|
|
|
Result: sucess
|
|
|
|
|
|
\subsection{Test 2: IPv6 egress}
|
|
Similar to the IPv4 setting before, just for IPv6.
|
|
|
|
Step 1: getting IP address values
|
|
|
|
\begin{verbatim}

\subsection{Test 3: NAT64}
|

Additionally to the preparations done in test 1 and 2, the following

Sometimes flashing bitfiles to the NetFPGA will fail. A random amount
|
|
of reboots (1 to 3) and a random amount of reflashing will fix this
|
|
problem.

Below can be found the log output from the flashing process.

A successful flashing process also emits a couple of errors, however
|
|
the message ``fpga configuration failed. DONE PIN is not HIGH'' and
|
|
its succeeding lines are missing, as seen below.
|
|
|
|
After that in all cases a reboot is required; the PCI rescan in no
|
|
tested case showed the nf devices.

\section{\label{chapterB:netpfga-nftraffic}NetFPGA misses packets on nf*}
|
|
While the nf devices appear in the operating system, packets emitted
|
|
by the netpfga cannot be sniffed on the nf interfaces
|
|
directly. Instead one has to sniff packets on a physical network card
|
|
that is connected to the specific output port.
