This section describes commonly-used -options and parameters. - -You can find command-line argument parsers in the source code by searching for -instances of the `VLIB_CONFIG_FUNCTION` macro. The invocation -`VLIB_CONFIG_FUNCTION(foo_config, "foo")` will cause the function -`foo_config` to receive all the options and values supplied in a parameter -block named "`foo`", for example: `foo { arg1 arg2 arg3 ... }`. - -@todo Tell the nice people where this document lives so that the might -help improve it! - -## Command-line arguments - -Parameters are grouped by a section name. When providing more than one -parameter to a section all parameters for that section must be wrapped in -curly braces. - -``` -/usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 } -``` - -Which will produce output similar to this: - - <startup diagnostic messages> - _______ _ _ _____ ___ - __/ __/ _ \ (_)__ | | / / _ \/ _ \ - _/ _// // / / / _ \ | |/ / ___/ ___/ - /_/ /____(_)_/\___/ |___/_/ /_/ - - vpp# <start-typing> - -When providing only one such parameter the braces are optional. For example, -the following command argument, `unix interactive` does not have braces: - -``` -/usr/bin/vpp unix interactive -``` - -The command line can be presented as a single string or as several; anything -given on the command line is concatenated with spaces into a single string -before parsing. - -VPP applications must be able to locate their own executable images. The -simplest way to ensure this will work is to invoke a VPP application by giving -its absolute path; for example: `/usr/bin/vpp <options>`. At startup, VPP -applications parse through their own ELF-sections (primarily) to make lists -of init, configuration, and exit handlers. - -When developing with VPP, in _gdb_ it's often sufficient to start an application -like this at the `(gdb)` prompt: - -``` -run unix interactive -``` - -## Configuration file - -It is also possible to supply parameters in a startup configuration file the -path of which is provided to the VPP application on its command line. - -The format of the configuration file is a simple text file with the same -content as the command line but with the benefit of being able to use newlines -to make the content easier to read. For example: - -``` -unix { - nodaemon - log /var/log/vpp/vpp.log - full-coredump - cli-listen localhost:5002 -} -api-trace { - on -} -dpdk { - dev 0000:03:00.0 -} -``` - -VPP is then instructed to load this file with the `-c` option: - -``` -/usr/bin/vpp -c /etc/vpp/startup.conf -``` - -## Index of startup command sections - -[TOC] - |
