Tested-by: Xiaonan Zhang <xiaonanx.zhang-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
- Tested Commit: Pablo
- OS: Fedora20 3.15.8-200.fc20.x86_64
- GCC: gcc version 4.8.3 20140624
- CPU: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz
- NIC: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb]
- Default x86_64-native-linuxapp-gcc configuration
- Total 6 cases, 6 passed, 0 failed
- Test Environment setup
- Topology #1: Create 2VMs (Fedora 20, 64bit);for each VM, pass through one physical port(Niantic 82599) to VM, and also create one virtual device: vmxnet3 in VM. Between two VMs, use one vswitch to connect 2 vmxnet3. In summary, PF1
and vmxnet3A are in VM1; PF2 and vmxnet3B are in VM2.The traffic flow for l2fwd/l3fwd is as below:
Ixia -> PF1 -> vmxnet3A -> vswitch -> vmxnet3B -> PF2 -> Ixia.
- Topology #2: Create 1VM (Fedora 20, 64bit), on this VM, created 2 vmxnet3, called vmxnet3A, vmxnet3B; create 2 vswitch, vswitchA connecting PF1 and vmxnet3A, while vswitchB connecting PF2 and vmxnet3B. The traffic flow is as below:
Ixia -> PF1 -> vswitchA -> vmxnet3A -> vmxnet3B -> vswitchB -> PF2 -> Ixia.
- Test Case1: L2fwd with Topology#1
Description: Set up topology#1(in prerequisite session), and bind PF1, PF2, Vmxnet3A, vmxnet3B to DPDK poll-mode driver (igb_uio).
Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see
if any unexpected behavior, such as no receives after N packets.
Command / instruction:
To run the l2fwd example in 2VMs:
./build/l2fwd -c f -n 4 -- -p 0x3
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to PF1, and the flow should have PF1's MAC as destination MAC. Check if ixia port2 have received the 5 packets.
Expected test result:
Passed
- Test Case2: L3fwd-VF with Topology#1
Description: Set up topology#1(in prerequisite session), and bind PF1, PF2, Vmxnet3A, vmxnet3B to DPDK poll-mode driver (igb_uio)
Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see
if any unexpected behavior, such as no receives after N packets.
Command / instruction:
To run the l3fwd-vf example in 2VMs:
./build/l3fwd-vf -c 0x6 -n 4 -- -p 0x3 --config "(0,0,1),(1,0,2)"
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to PF1, and the flow should have PF1's MAC as destination MAC and have 2.1.1.x as destination IP. Check if ixia port2 have received the 5 packets.
Expected test result:
Passed
- Test Case3: L2fwd with Topology#2
Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igb_uio).
Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see
if any unexpected behavior, such as no receives after N packets.
Command / instruction:
To run the l2fwd example in VM1:
./build/l2fwd -c f -n 4 -- -p 0x3
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to port0 (vmxnet3A), and the flow should have port0's MAC as destination MAC. Check if ixia port2 have received the 5 packets. Similar things need to be done at ixia port2.
Expected test result:
Passed
- Test Case4: L3fwd-VF with Topology#2
Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igb_uio).
Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see
if any unexpected behavior, such as no receives after N packets.
Command / instruction:
To run the l3fwd-vf example in VM1:
./build/l3fwd-vf -c 0x6 -n 4 -- -p 0x3 --config "(0,0,1),(1,0,2)"
- Test IXIA Flow prerequisite: Ixia port1 sends 5 packets to port0(vmxnet3A), and the flow should have port0's MAC as destination MAC and have 2.1.1.x as destination IP. Check if ixia port2 have received the 5 packets.
Expected test result:
Passed
- Test Case5: Timer test with Topology#2
Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igb_uio).
Command / instruction:
Build timer sample and run the sample:
./build/timer -c f -n 4
- Test IXIA Flow prerequisite: N.A.
Expected test result:
Passed
- Test Case6: Testpmd basic with Topology#2
Description: Set up topology#2(in prerequisite session), and bind vmxnet3A and vmxnet3B to DPDK poll-mode driver (igbuio).
Increase the flow at line rate (uni-directional traffic), send the flow at different packet size (64bytes, 128bytes, 256bytes, 512bytes, 1024bytes, 1280bytes and 1518bytes) and check the received packets/rate to see
if any unexpected behavior, such as no receives after N packets.
Command / instruction:
Run testpmd(e.g:/x86_64-native-linuxapp-gcc/app/testpmd) with below command lines:
./testpmd -c f -n 4 -- --txqflags=0xf01 -i
Clean environment and start the forwarding. Need check the port information and clear port statics by using below commands:
Testpmd>show port info all
Testpmd>clear port stats all
Testpmd>show port stats all
Testpmd>set fwd mac
Testpmd>start
- Test IXIA Flow prerequisite: N.A.
Expected test result:
Passed
