 The position of the entry in the code reflects its position in the actual menu. That is, if the first entry in the subtree of config_main is the struct menu_node rstp then it will also be the first entry in the CLI menu. Notice than when one of the entries is selected then the cmd_rstp_run routine is called.

 The //run// field from struct menu_node represents a pointer to a function having the following signature : int (struct cli_context *, int, char **, struct menu_node **). For a detailed description see the struct menu_node definition in **cli/cli.h**. So, first thing to do is define a routine called cmp_rstp_run having this signature in the **cli/command/config_if.h** header.

+== Step 5 : implementing the interface enable/disable routine ==
+The cmd_rstp_if_set routine's job is to send a message to the daemon implementing the protocol that it wants a specific interface to be enabled/disabled. This requires an interprocess communication mechanism between the daemon and the CLI process. It involves the daemon creating a thread specifically for this task. The details are not related to the menu entries so they won't be described here.
