Use testpmd to test the mode 0, 1, 2, 3, 4, 5, use bond_app to test the mod=
e 6. If test the mode 6, Set the tester port address to=20
7.0.0.1, 7.0.0.2, 7.0.0.3. And it will be better to turn on the debug switc=
h on the config:
CONFIG_RTE_LIBRTE_BOND_DEBUG_ALB=3Dn - deeper debug, if you want all arp an=
d ipv4 packets be printed=20
CONFIG_RTE_LIBRTE_BOND_DEBUG_ALB_L1=3Dn - don't print packets information, =
just collects statistics from clients, you can print these statistics with =
show command.
Test Case1: Mode 6(Adaptive load balance) Basic test

Verify basic commands of bond_app work well.
Use Setup#3
Now bond_app has commands of send, start, stop, show, help, quit
help:
execute command 'help' in the bond_app, verify it will print all comm=
ands help info.
send:
make sure that bond_app has been started, execute command 'send 7.0.0.1'=
on server, use=20
tcpdump to listen client1 port , verify the port will receive ARP reques=
ts.
start:
step1:
execute command 'stop' in the bond_app, then execute 'arping -c=
1 -I device 7.0.0.10' on the client1,
verify bond_app will not receive and reply the client1 ARP requ=
est.
Step2:
Execute command 'start' in the bond_app, then execute 'arping -=
c 1 -I device 7.0.0.10' on the client1,
Verify bond_app will receive and reply the client1 ARP request.
stop:
continue the test of command 'start', rerun step1.
show:
execute command 'show' in the bond_app, verify it will print some bon=
d info: ex. active slaves etc.
quit:
execute command 'quit' in the bond_app, verify it will terminate all t=
hreads and quit.
=20
Verify bond_app can check the state of slaves, and do some actions.
Use Setup#1
Start bond_app.
Step1:
Send 1 ARP request packet to bond0 from client1, verify it will recei=
ve and reply it on one slave.
Step2:
Bring the port of client1 link down, verify bond0 will detect the chang=
e of slaves, by the command
'show' to check the state of bond0, verify there are just two slaves.
Step3:
Send 1 ARP request packet to bond0 on bond1 from client1, verify it w=
ill receive nothing.
Test Case2: Mode 6(Adaptive load balance) RX test of mode6

=3D=3D
Verify bond device can receive load balancing for IPV4 traffic.
Use Setup#3
Step1:
Send ARP request packet (no VLAN header) to bond0 from each client, v=
erify bond0 will choose=20
different slave to reply the request by the policy of round-robin.
You can use the command 'arping -c 1 -I device 7.0.0.10' to server on=
each client. The device will
need you to change it to the interface name of your client.
Step2:
Send ARP request packet tagged with VLAN header to bond0 from each cl=
ient, verify bond0 will
choose different slave to reply the request by the policy of round-ro=
bin. The VLAN header will not
affect the policy of choosing slave to reply the request.
You can use the scapy to send these packet as below:
=20
>>> eth =3D Ether(src=3D'choose-client-port-mac')
>>> arp =3D ARP(hwsrc=3D'choose-client-port-mac', psrc=3D'choose-port=
-ip', pdst=3D'7.0.0.10')
>>> dot1q =3D Dot1Q(vlan=3D1)
>>> packet =3D eth/dot1q/arp
>>> recv =3D srp1(packet, iface=3D'choose-port-interface-name', timeo=
ut=3D2)
Test Case3: Mode 6(Adaptive load balance) TX test of mode6
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D
Verify bond device can transmit load balance.
Use Setup#3
Use scapy to send 1000 IP packets to bond0, verify slave0, slave1 and slave=
2 will transmit packets like this:
average =3D packet_num / slave_num; average*0.9 < slave_transmit_num < 1.1*=
average; so each slave
will receive packets between 300 and 367.
You can use scapy to send packets as below:
>>> eth =3D Ether(src=3D'choose-client-port-mac')
>>> ip =3D IP(len=3D66, dst=3D'7.0.0.10')
>>> packet =3D eth/ip
>>> sendp(packet, iface=3D'choose-port-interface-name', count=3D1000)
