+
+test steps
+----------
+
+1. Launch the app ``testpmd``, start primary process and secondary process with the following arguments::
+
+   ./dpdk-testpmd -l 1,2 --proc-type=auto -a 0000:17:00.0  --log-level=ice,7 -- -i  --rxq=4 --txq=4 --num-procs=2 --proc-id=0
+   ./dpdk-testpmd -l 3,4 --proc-type=auto -a 0000:17:00.0  --log-level=ice,7 -- -i  --rxq=4 --txq=4 --num-procs=2 --proc-id=1
+
+2. reset port in secondary process::
+
+    secondary process:
+      testpmd> port stop 0
+      testpmd> port reset 0
+
+expected result
+---------------
+
+   Check that there are no ``core dump`` messages in the output.
