4 | There are five routing daemons in use, and there is one manager daemon. | |
5 | These daemons may be located on separate machines from the manager | |
6 | daemon. Each of these daemons will listen on a particular port for | |
7 | incoming VTY connections. The routing daemons are: | |

42 | ||
43 | In a config file, you can write the debugging options, a vty's password, | |
44 | routing daemon configurations, a log file name, and so forth. This | |
45 | information forms the initial command set for a routing beast as it is | |
46 | starting. | |
47 | ||
48 | Config files are generally found in: | |
49 | ||
a20a4060 | 50 | @itemize @w{} |
718e3744 | 51 | @item @file{@value{INSTALL_PREFIX_ETC}/*.conf} |
52 | @end itemize | |
53 | ||
54 | Each of the daemons has its own | |
55 | config file. For example, zebra's default config file name is: | |
56 | ||
a20a4060 | 57 | @itemize @w{} |
718e3744 | 58 | @item @file{@value{INSTALL_PREFIX_ETC}/zebra.conf} |
59 | @end itemize | |
60 | ||
61 | The daemon name plus @file{.conf} is the default config file name. You | |
62 | can specify a config file using the @kbd{-f} or @kbd{--config-file} | |
63 | options when starting the daemon. | |

70 | @deffn Command {hostname @var{hostname}} {} | |
71 | Set hostname of the router. | |
72 | @end deffn | |
73 | ||
74 | @deffn Command {password @var{password}} {} | |
75 | Set password for vty interface. If there is no password, a vty won't | |
76 | accept connections. | |
77 | @end deffn | |
78 | ||
79 | @deffn Command {enable password @var{password}} {} | |
80 | Set enable password. | |
81 | @end deffn | |
82 | ||
274a4a44 | 83 | @deffn Command {log trap @var{level}} {} |
84 | @deffnx Command {no log trap} {} | |
85 | These commands are deprecated and are present only for historical compatibility. | |
86 | The log trap command sets the current logging level for all enabled | |
87 | logging destinations, and it sets the default for all future logging commands | |
88 | that do not specify a level. The normal default | |
89 | logging level is debugging. The @code{no} form of the command resets | |
90 | the default level for future logging commands to debugging, but it does | |
91 | not change the logging level of existing logging destinations. | |
92 | @end deffn | |
93 | ||
94 | ||
718e3744 | 95 | @deffn Command {log stdout} {} |
274a4a44 | 96 | @deffnx Command {log stdout @var{level}} {} |
718e3744 | 97 | @deffnx Command {no log stdout} {} |
274a4a44 | 98 | Enable logging output to stdout. |
99 | If the optional second argument specifying the | |
100 | logging level is not present, the default logging level (typically debugging, | |
101 | but can be changed using the deprecated @code{log trap} command) will be used. | |
102 | The @code{no} form of the command disables logging to stdout. | |
103 | The @code{level} argument must have one of these values: | |
104 | emergencies, alerts, critical, errors, warnings, notifications, informational, or debugging. Note that the existing code logs its most important messages | |
105 | with severity @code{errors}. | |
718e3744 | 106 | @end deffn |
107 | ||
108 | @deffn Command {log file @var{filename}} {} | |
274a4a44 | 109 | @deffnx Command {log file @var{filename} @var{level}} {} |
110 | @deffnx Command {no log file} {} | |
111 | If you want to log into a file, please specify @code{filename} as | |
112 | in this example: | |
718e3744 | 113 | @example |
438f5286 | 114 | log file /var/log/frr/bgpd.log informational |
718e3744 | 115 | @end example |
274a4a44 | 116 | If the optional second argument specifying the |
117 | logging level is not present, the default logging level (typically debugging, | |
118 | but can be changed using the deprecated @code{log trap} command) will be used. | |
119 | The @code{no} form of the command disables logging to a file. | |
c70257d0 | 120 | |
121 | Note: if you do not configure any file logging, and a daemon crashes due | |
122 | to a signal or an assertion failure, it will attempt to save the crash | |
438f5286 | 123 | information in a file named /var/tmp/frr.<daemon name>.crashlog. |
c70257d0 | 124 | For security reasons, this will not happen if the file exists already, so |
125 | it is important to delete the file after reporting the crash information. | |

128 | @deffn Command {log syslog} {} | |
274a4a44 | 129 | @deffnx Command {log syslog @var{level}} {} |
718e3744 | 130 | @deffnx Command {no log syslog} {} |
274a4a44 | 131 | Enable logging output to syslog. |
132 | If the optional second argument specifying the | |
133 | logging level is not present, the default logging level (typically debugging, | |
134 | but can be changed using the deprecated @code{log trap} command) will be used. | |
135 | The @code{no} form of the command disables logging to syslog. | |

274a4a44 | 138 | @deffn Command {log monitor} {} |
139 | @deffnx Command {log monitor @var{level}} {} | |
140 | @deffnx Command {no log monitor} {} | |
141 | Enable logging output to vty terminals that have enabled logging | |
142 | using the @code{terminal monitor} command. | |
143 | By default, monitor logging is enabled at the debugging level, but this | |
144 | command (or the deprecated @code{log trap} command) can be used to change | |
145 | the monitor logging level. | |
146 | If the optional second argument specifying the | |
147 | logging level is not present, the default logging level (typically debugging, | |
148 | but can be changed using the deprecated @code{log trap} command) will be used. | |
149 | The @code{no} form of the command disables logging to terminal monitors. | |
718e3744 | 150 | @end deffn |
151 | ||
274a4a44 | 152 | @deffn Command {log facility @var{facility}} {} |
153 | @deffnx Command {no log facility} {} | |
154 | This command changes the facility used in syslog messages. The default | |
155 | facility is @code{daemon}. The @code{no} form of the command resets | |
156 | the facility to the default @code{daemon} facility. | |
718e3744 | 157 | @end deffn |
158 | ||
274a4a44 | 159 | @deffn Command {log record-priority} {} |
160 | @deffnx Command {no log record-priority} {} | |
161 | To include the severity in all messages logged to a file, to stdout, or to | |
162 | a terminal monitor (i.e. anything except syslog), | |
163 | use the @code{log record-priority} global configuration command. | |
164 | To disable this option, use the @code{no} form of the command. By default, | |
165 | the severity level is not included in logged messages. Note: some | |
166 | versions of syslogd (including Solaris) can be configured to include | |
167 | the facility and level in the messages emitted. | |

170 | @deffn Command {log timestamp precision @var{<0-6>}} {} |
171 | @deffnx Command {no log timestamp precision} {} | |
172 | This command sets the precision of log message timestamps to the | |
173 | given number of digits after the decimal point. Currently, | |
174 | the value must be in the range 0 to 6 (i.e. the maximum precision | |
175 | is microseconds). | |
176 | To restore the default behavior (1-second accuracy), use the | |
177 | @code{no} form of the command, or set the precision explicitly to 0. | |

181 | log timestamp precision 3 | |
182 | @end group | |

223 | Set VTY connection timeout value. When only one argument is specified | |
224 | it is used for timeout value in minutes. Optional second argument is | |
225 | used for timeout value in seconds. Default timeout value is 10 minutes. | |
226 | When timeout value is zero, it means no timeout. | |

243 | ||
244 | @example | |
245 | @group | |
246 | ! | |
247 | ! Zebra configuration file | |

257 | @end example | |
258 | ||
259 | '!' and '#' are comment characters. If the first character of the word | |
260 | is one of the comment characters then from the rest of the line forward | |
261 | will be ignored as a comment. | |
262 | ||
263 | @example | |
264 | password zebra!password | |
265 | @end example | |
266 | ||
267 | If a comment character is not the first character of the word, it's a | |
268 | normal character. So in the above example '!' will not be regarded as a | |
269 | comment and the password is set to 'zebra!password'. | |

343 | Upon startup the process identifier of the daemon is written to a file, | |
344 | typically in @file{/var/run}. This file can be used by the init system | |
345 | to implement commands such as @command{@dots{}/init.d/zebra status}, | |
346 | @command{@dots{}/init.d/zebra restart} or @command{@dots{}/init.d/zebra | |
347 | stop}. | |
348 | ||
349 | The file name is an run-time option rather than a configure-time option | |
350 | so that multiple routing daemons can be run simultaneously. This is | |
76b89b4a | 351 | useful when using @value{PACKAGE_NAME} to implement a routing looking glass. One |
718e3744 | 352 | machine can be used to collect differing routing views from differing |

378 | ||
379 | FRR supports loading extension modules at startup. Loading, reloading or | |
380 | unloading modules at runtime is not supported (yet). To load a module, use | |
381 | the following command line option at daemon startup: | |
382 | ||
383 | @table @samp | |
384 | @item -M @var{module:options} | |
385 | @itemx --module @var{module:options} | |

387 | Load the specified module, optionally passing options to it. If the module | |
388 | name contains a slash (/), it is assumed to be a full pathname to a file to | |
389 | be loaded. If it does not contain a slash, the | |
390 | @code{@value{INSTALL_PREFIX_MODULES}} directory is searched for a module of | |
391 | the given name; first with the daemon name prepended (e.g. @code{zebra_mod} | |
392 | for @code{mod}), then without the daemon name prepended. | |
393 | ||
394 | This option is available on all daemons, though some daemons may not have | |
395 | any modules available to be loaded. | |
396 | @end table | |

399 | @subsection The SNMP Module | |
400 | ||
401 | If SNMP is enabled during compile-time and installed as part of the package, | |
402 | the @code{snmp} module can be loaded for the @command{zebra}, | |
403 | @command{bgpd}, @command{ospfd}, @command{ospf6d} and @command{ripd} daemons. | |
404 | ||
405 | The module ignores any options passed to it. Refer to @ref{SNMP Support} | |
406 | for information on its usage. | |
407 | ||
408 | ||
409 | @subsection The FPM Module | |
410 | ||
411 | If FPM is enabled during compile-time and installed as part of the package, | |
412 | the @code{fpm} module can be loaded for the @command{zebra} daemon. This | |
413 | provides the Forwarding Plane Manager ("FPM") API. | |
414 | ||
415 | The module expects its argument to be either @code{netlink} or | |
416 | @code{protobuf}, specifying the encapsulation to use. @code{netlink} is the | |
417 | default, and @code{protobuf} may not be available if the module was built | |
418 | without protobuf support. Refer to @ref{zebra FIB push interface} for more | |
419 | information. | |

442 | ||
443 | To enable a VTY interface, you have to setup a VTY password. If there | |
444 | is no VTY password, one cannot connect to the VTY interface at all. | |
