531  * @cfgcmd{nodaemon}

540  * only the last will have an effect.

542  * @cfgcmd{log, &lt;filename&gt;}
543  * Logs the startup configuration and all subsequent CLI commands in
544  * @c filename.
545  * Very useful in situations where folks don't remember or can't be bothered

547  *
548  * @cfgcmd{pidfile, &lt;filename&gt;}
549  * Writes the pid of the main thread in @c filename.

553  * of just text+data+bss.
554  *
555  * @cfgcmd{runtime-dir}
556  * Define directory where VPP is going to store all runtime files.
557  * Default is /run/vpp.
558  *
559  * @cfgcmd{cli-listen, &lt;address:port&gt;}
560  * Bind the CLI to listen at the address and port given. @clocalhost
561  * on TCP port @c 5002, given as <tt>cli-listen localhost:5002</tt>,
562  * is typical.
563  *
564  * @cfgcmd{cli-line-mode}
565  * Disable character-by-character I/O on stdin. Useful when combined with,
566  * for example, <tt>emacs M-x gud-gdb</tt>.
567  *
568  * @cfgcmd{cli-prompt, &lt;string&gt;}
569  * Configure the CLI prompt to be @c string.
570  *
571  * @cfgcmd{cli-history-limit, &lt;nn&gt;}
572  * Limit commmand history to @c nn lines. A value of @c 0
573  * disables command history. Default value: @c 50
574  *
575  * @cfgcmd{cli-no-banner}
