80.5.1. tester Configuration

#. send dual vlan packet with scapy, verify packets can filter to the corresponding VF queues:: 7. send qinq packet with traffic generator, verify packets can filter to the corresponding VF queues.

80.6. Note

  1. How to send packet with specific TPID with scapy:

    1. wrpcap("qinq.pcap",[Ether(dst="3C:FD:FE:A3:A0:AE")/Dot1Q(type=0x8100,vlan=1)/Dot1Q(type=0x8100,vlan=4092)/IP(src="192.168.0.1", dst="192.168.0.2")/Raw('x' * 20)]).
2. hexedit qinq.pcap; change tpid field, "ctrl+w" to save, "ctrl+x" to exit.
3. sendp(rdpcap("qinq.pcap"), iface="eth17").
