 ## Doca Sensitive Information Detection example for TCP traffic
 
 The DOCA example is similar to the Sensitive Information Detection (SID) example in that it uses the `sid-minibert` model in conjunction with the `TritonInferenceStage` to detect sensitive information. The difference is that the sensitive information we will be detecting is obtained from a live TCP packet stream provided by a `DocaSourceStage`.
 To run the example from the Morpheus root directory and capture all TCP network traffic from the given NIC, use the following command and replace the `nic_addr` and `gpu_addr` arguments with your NIC and GPU PCIe addresses.
 ```
-# python examples/doca/run_tcp.py --nic_addr cc:00.1 --gpu_addr cf:00.0 --traffic_type tcp
+# python examples/doca/run_tcp.py --nic_addr cc:00.1 --gpu_addr cf:00.0
