-For example, to switch to port 8000, you would use the following command:
+Trap automatically recognizes the type of traffic.
+Therefore, there is no need to open separate ports for different protocols.
+By default, it operates on port `9912`.
+However, if you wish to utilize a different port, you can easily make this adjustment using the `-p` option:
