Following NSH_SFC functional test areas are covered in the CSIT |release| with\r
results listed in this report:\r
\r
-- **NSH SFC Classifier** - TG send some TCP packets to test NSH SFC\r
+- **NSH SFC Classifier** - TG sends some TCP packets to test NSH SFC\r
Classifier functional. DUT1 will receive these packets from one NIC and loopback\r
the VXLAN-GPE-NSH encapsulated packets to the TG from other NIC.\r
- Test case count: 7\r
-- **NSH SFC Proxy Inbound** - TG send some VXLAN-GPE-NSH encapsulated packets\r
+- **NSH SFC Proxy Inbound** - TG sends some VXLAN-GPE-NSH encapsulated packets\r
to test NSH SFC Proxy Inbound functional. DUT1 will receive these packets from one\r
NIC and loopback the VXLAN encapsulated packets to the TG from other NIC.\r
- Test case count: 6\r
-- **NSH SFC Proxy Outbound** - TG send some VXLAN encapsulated packets to test\r
+- **NSH SFC Proxy Outbound** - TG sends some VXLAN encapsulated packets to test\r
NSH SFC Proxy Outbound functional. DUT1 will receive these packets from one NIC\r
and loopback the VXLAN-GPE-NSH encapsulated packets to the TG from other NIC.\r
- Test case count: 6\r
-- **NSH SFC Service Function Forward** - TG send some VXLAN-GPE-NSH encapsulated\r
+- **NSH SFC Service Function Forward** - TG sends some VXLAN-GPE-NSH encapsulated\r
packets to test NSH SFC Service Function Forward functional. DUT1 will receive these\r
packets from one NIC and swap the VXLAN-GPE-NSH header, after that DUT1 loopback the\r
VXLAN-GPE-NSH encapsulated packtes to the TG from other NIC.\r
