Get the pci device id and interface of DUT and tester.
For example, 0000:3b:00.0 and 0000:3b:00.1 is pci device id,
ens785f0 and ens785f1 is interface:
<dpdk dir># ./usertools/dpdk-devbind.py -s
0000:3b:00.0 'Device 159b' if=ens785f0 drv=ice unused=vfio-pci
0000:3b:00.1 'Device 159b' if=ens785f1 drv=ice unused=vfio-pci
Bind the DUT port to dpdk:
<dpdk dir># ./usertools/dpdk-devbind.py -b vfio-pci <DUT port pci device id>
32.3.1. Common Steps¶
All the packets in this test plan use below settings:
dst mac: 68:05:CA:C1:BA:28
ipv4 src: 192.168.0.2
ipv4 dst: 192.168.0.3
ipv6 src: 2001::2
ipv6 dst: 2001::3
sport: 1026
dport: 1027
count: 3
Set fwd engine:
testpmd> set fwd rxonly
Set verbose:
testpmd> set verbose 1
Start testpmd:
testpmd> start
Send ether packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv4 packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv6 packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv4-udp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/UDP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv6-udp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/UDP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv4-tcp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/TCP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv6-tcp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/TCP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv4-sctp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IP(src="<ipv4 src>",dst="<ipv4 dst>")/SCTP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
Send ipv6-sctp packets, record the timestamp values and check the timestamp values are incremented:
>>> sendp([Ether(dst="<dst mac>")/IPv6(src="<ipv6 src>",dst="<ipv6 dst>")/SCTP(sport=<sport>, dport=<dport>)/("X"*480)], iface="<tester interface>",count=<count>)
32.3.2. Test Case 1: Without timestamp, check no timestamp¶
This case is designed to check no timestamp value while testpmd not enable rx timestamp.
32.3.2.1. Test Steps¶
Start testpmd with different command line:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 3b:00.0 -- -i --rxq=16 --txq=16
Send packets as common steps, check no timestamp value.
32.3.3. Test Case 2: Single queue With timestamp, check timestamp¶
This case is designed to check single queue has timestamp values and the timestamp values are incremented.
32.3.3.1. Test Steps¶
Start testpmd with different command line:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -c f -n 4 -a 3b:00.0 -- -i --enable-rx-timestamp
Send packets as common steps, check single queue has timestamp values and the timestamp values are incremented.
