==================
Port Control Tests
==================
Prerequisites
=============
1. Hardware:
* Fortville
* Niantic
* Columbiaville
* i350 NIC
* e1000 emulated device
Test Case: pf start/stop/reset/close
====================================
1. Bind the port to dpdk driver::
./usertools/dpdk-devbind.py -b igb_uio 18:00.2
2. Run testpmd::
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xff -n 4 -- -i
testpmd> set fwd mac
testpmd> start
check port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 1000 Mbps
verify that the link status is up.
Using scapy to send 1000 random packets from tester,
verify the packets can be received and can be forwarded::
scapy
>>>sendp([Ether(dst="00:11:22:33:44:11")/IP()/Raw('x'*40)], \
iface="enp27s0f2",count=1000)
3. Stop and start port::
testpmd> stop
testpmd> port stop all
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: down
Link speed: 0 Mbps
verify that the link status is down.
Then start the port::
testpmd> port start all
testpmd> start
check port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 10000 Mbps
verify that the link status is up.
Send the same 1000 packets with scapy from tester,
verify the packets can be received and forwarded.
4. Reset the port, run the commands::
testpmd> stop
testpmd> port stop all
testpmd> port reset all
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: down
Link speed: 0 Mbps
verify that the link status is down.
Then start the port::
testpmd> port start all
testpmd> start
check port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 10000 Mbps
verify that the link status is up.
Send the same 1000 packets with scapy from tester,
verify the packets can be received and forwarded.
5. Close the port, run the commands::
testpmd> stop
testpmd> port stop all
testpmd> port close all
check the port info::
testpmd> show port info all
testpmd>
verify that there is no output after executing this command.
Test Case: e1000 emulated device start/stop/reset/close
=======================================================
1. Set up qemu environment
Virtual an e1000 emulated device in vm, then start
vm with the following command::
qemu-system-x86_64 -enable-kvm -m 16G -vnc :20 \
-smp cores=10,sockets=1 -cpu host -hda ./u18.img \
-device e1000,netdev=net1,mac=00:01:02:33:44:22 \
-netdev user,id=net1,hostfwd=tcp:10.67.119.144:6666-:22 \
-device e1000,netdev=net2,mac=00:01:02:33:44:33 \
-netdev user,id=net2,hostfwd=tcp:10.67.119.144:7777-:23 \
-monitor stdio
Login vm, get the pci device id of the e1000 emulated device,
assume it is 0000:00:03.0, bind it to igb_uio driver, and then
start testpmd::
./usertools/dpdk-devbind.py -b igb_uio 0000:00:03.0
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- -i
testpmd-> set fwd mac
testpmd-> start
check port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 1000 Mbps
verify that the link status is up.
2. Stop and start port (not support)::
testpmd> stop
testpmd> port stop all
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: down
Link speed: 0 Mbps
verify that the link status is down.
Then start the port::
testmd-> port start all
testpmd> start
check the port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 10000 Mbps
verify that the link status is up.
3. Reset the port (not support)::
testpmd> stop
testpmd> port stop all
testpmd> port reset all
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: down
Link speed: 0 Mbps
verify that the link status is down.
Then start the port::
testpmd> port start all
testpmd> start
check the port info::
testpmd> show port info all
********************* Infos for port 0 *********************
Link status: up
Link speed: 10000 Mbps
verify that the link status is up.
4. Close the port::
testpmd> stop
testpmd> port stop all
testpmd> port close all
check the port info::
testpmd> show port info all
testpmd>
verify that there is no output after executing this command.
