| * |
| * @cfgcmd{interactive} |
| * Attach CLI to stdin/out and provide a debugging command line interface. |
| * Implies @c nodaemon. |
| * |
| * @cfgcmd{nodaemon} |
| * Do not fork or background the VPP process. Typically used when invoking |
| * VPP applications from a process monitor. |
| * |
| * @cfgcmd{nosyslog} |
| * Do not send e.g. clib_warning(...) output to syslog. Used |
| * when invoking VPP applications from a process monitor which |
| * pipe stdout/stderr to a dedicated logger service. |
| * |
| * @cfgcmd{exec, <filename>} |
| * @par <code>startup-config <filename></code> |
| * Read startup operational configuration from @c filename. |
| * The contents of the file will be performed as though entered at the CLI. |
| * The two keywords are aliases for the same function; if both are specified, |
| * only the last will have an effect. |
| * |
| * @cfgcmd{log, <filename>} |
| * Logs the startup configuration and all subsequent CLI commands in |
| * @c filename. |
| * Very useful in situations where folks don't remember or can't be bothered |
| * to include CLI commands in bug reports. |
| * |
| * @cfgcmd{pidfile, <filename>} |
| * Writes the pid of the main thread in @c filename. |
| * |
| * @cfgcmd{full-coredump} |
| * Ask the Linux kernel to dump all memory-mapped address regions, instead |
| * of just text+data+bss. |
| * |
| * @cfgcmd{runtime-dir} |
| * Define directory where VPP is going to store all runtime files. |
| * Default is /run/vpp when running as root, /run/user/<UID>/vpp if running as |
| * an unprivileged user. |
| * |
| * @cfgcmd{cli-listen, <address:port>} |
| * Bind the CLI to listen at the address and port given. @c localhost |
| * on TCP port @c 5002, given as <tt>cli-listen localhost:5002</tt>, |
| * is typical. |
| * |
| * @cfgcmd{cli-line-mode} |
| * Disable character-by-character I/O on stdin. Useful when combined with, |
| * for example, <tt>emacs M-x gud-gdb</tt>. |
| * |
| * @cfgcmd{cli-prompt, <string>} |
| * Configure the CLI prompt to be @c string. |
| * |
| * @cfgcmd{cli-history-limit, <nn>} |
| * Limit command history to @c nn lines. A value of @c 0 |
| * disables command history. Default value: @c 50 |
| * |
| * @cfgcmd{cli-no-banner} |
| * Disable the login banner on stdin and Telnet connections. |
| * |
| * @cfgcmd{cli-no-pager} |
| * Disable the output pager. |
| * |
| * @cfgcmd{cli-pager-buffer-limit, <nn>} |
| * Limit pager buffer to @c nn lines of output. |
| * A value of @c 0 disables the pager. Default value: @c 100000 |
| * |
| * @cfgcmd{gid, <nn>} |
| * Set the effective gid under which the vpp process is to run. |
| * |
| * @cfgcmd{poll-sleep-usec, <nn>} |
| * Set a fixed poll sleep interval between main loop polls. |
