Test Setup#1 for Functional test
================================
Tester has 4 ports(portA--portD), and DUT has 4 ports(port0--port3), then
connect portA to port0, portB to port1, portC to port2, portD to port3.
Test Setup#2 for Functional test
================================
Tester has 2 ports(portA--portB), DUT has 4 ports(port0--port3), and a switch
that supports IEEE 802.3ad Dynamic link aggregation, then connect port0-port2
to the switch for dynamic link aggregation, connect portA to aggregated
interface on the switch, connect portB to port3.
Test Setup#3 for Functional test
================================
Tester has 3 ports(portA--portC), DUT has 3 ports(port0--port2), and a switch,
then connect port0-port2 to three ports on the switch, connect portA - portB to
the other three ports on the switch.
Test App
===============================
Use testpmd to test the mode 0, 1, 2, 3, 4, 5, use bond_app to test the mode 6.
If test the mode 6, Set the tester port address to
7.0.0.1, 7.0.0.2, 7.0.0.3. And it will be better to turn on the debug switch on
the config:
CONFIG_RTE_LIBRTE_BOND_DEBUG_ALB=n - deeper debug, if you want all arp and ipv4
packets be printed
CONFIG_RTE_LIBRTE_BOND_DEBUG_ALB_L1=n - 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 commands
help info.
send:
make sure that bond_app has been started, execute command 'send
7.0.0.1' on server, use
tcpdump to listen client1 port , verify the port will receive ARP
requests.
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 request.
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 bond
info: ex. active slaves etc.
quit:
execute command 'quit' in the bond_app, verify it will terminate all
threads and quit.
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 receive
and reply it on one slave.
Step2:
Bring the port of client1 link down, verify bond0 will detect the
change 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 will
receive nothing.
Test Case2: Mode 6(Adaptive load balance) RX test of mode6
=============================================================================
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,
verify bond0 will choose
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
client, verify bond0 will
choose different slave to reply the request by the policy of round-robin.
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:
>>> eth = Ether(src='choose-client-port-mac')
>>> arp = ARP(hwsrc='choose-client-port-mac', psrc='choose-port-ip',
pdst='7.0.0.10')
>>> dot1q = Dot1Q(vlan=1)
>>> packet = eth/dot1q/arp
>>> recv = srp1(packet, iface='choose-port-interface-name', timeout=2)
Test Case3: Mode 6(Adaptive load balance) TX test of mode6
=============================================================================
Verify bond device can transmit load balance.
Use Setup#3
Use scapy to send 1000 IP packets to bond0, verify slave0, slave1 and slave2
will transmit packets like this:
average = 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 = Ether(src='choose-client-port-mac')
>>> ip = IP(len=66, dst='7.0.0.10')
>>> packet = eth/ip
>>> sendp(packet, iface='choose-port-interface-name', count=1000)
