ip addr add 10.0.0.42/24 dev enp2s0f0
# Adding necessary ARP entries: for the virtual IPv4 address(es)
ip neigh add 10.0.0.6 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0

\subsection{Test 1: do IPv4 egress settings work}
Scenario: simple egress port setting
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}
>> table_cam_add_entry realmain_v4_networks_0 realmain.set_egress_port 167772202 => 16 0 0 0 0
fields = [(u'hit', 1), (u'action_run', 3), (u'out_port', 8), (u'out_port', 8), (u'mac_addr', 48), (u'task', 16), (u'table_id', 16)]
action_name = TopPipe.realmain.set_egress_port
field_vals = [1, '16', '0', '0', '0', '0']
CAM_Init_ValidateContext() - done
WROTE 0x44020250 = 0xa00002a
WROTE 0x44020280 = 0x0000
WROTE 0x44020284 = 0x0000
WROTE 0x44020288 = 0x10000000
WROTE 0x4402028c = 0x0001
READ 0x44020244 = 0x0001
WROTE 0x44020240 = 0x0001
READ 0x44020244 = 0x0001
READ 0x44020244 = 0x0001
success
>> table_cam_add_entry realmain_v4_networks_0 realmain.set_egress_port 167772164 => 16 0 0 0 0
fields = [(u'hit', 1), (u'action_run', 3), (u'out_port', 8), (u'out_port', 8), (u'mac_addr', 48), (u'task', 16), (u'table_id', 16)]
action_name = TopPipe.realmain.set_egress_port

success

Step 3: setting arp entries
\begin{verbatim}
root@ESPRIMO-P956:~# ip neigh add 10.0.0.6 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0
root@ESPRIMO-P956:~# ip neigh add 10.0.0.4 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0
\end{verbatim}
Step 3: generating test packets, expecting 4 packets to show up on
enp2s0f0:
\begin{tiny}
\begin{verbatim}
nico@ESPRIMO-P956:~$ sudo tcpdump -ni enp2s0f0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on enp2s0f0, link-type EN10MB (Ethernet), capture size 262144 bytes
10:49:28.200407 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 1, length 64
10:49:28.200445 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 1, length 64
10:49:29.222340 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 2, length 64
10:49:29.222418 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 2, length 64
\end{verbatim}
\end{tiny}
Result: sucess
