## DESCRIPTION

**ryu-manager** is the executable for Ryu applications. ryu-manager loads Ryu applications and run it.

Ryu is a component-based software defined networking framework. Ryu provides software components with well defined API that make it easy for developers to create new network management and control applications.

## OPTIONS

- **app**

  application module name to run

- **-h, --help**

  show this help message and exit

  Path to a config directory to pull \*.conf files from. This file set is sorted, so as to provide a predictable parse order if individual options are over-ridden. The set is parsed after the file(s) specified via previous --config-file, arguments hence over-ridden options in the directory take precedence.

- **--config-file** *PATH*

  Path to a config file to use. Multiple config files can be specified, with values in later files taking precedence. The default files used are: None

  controller certificate

- **--ctl-privkey** *CTL\_PRIVKEY*

  controller private key

- **--default-log-level** *DEFAULT\_LOG\_LEVEL*

  default log level

- **--explicit-drop**

  link discovery: explicitly drop lldp packet in

- **--install-lldp-flow**

  link discovery: explicitly install flow entry to send lldp packet to controller

- **--log-config-file** *LOG\_CONFIG\_FILE*

  Path to a logging config file to use

- **--log-dir** *LOG\_DIR*

  log file directory

- **--log-file** *LOG\_FILE*

  log file name

- **--log-file-mode** *LOG\_FILE\_MODE*

  default log file permission

- **--neutron-admin-auth-url** *NEUTRON\_ADMIN\_AUTH\_URL*

  auth url for connecting to neutron in admin context

- **--neutron-admin-password** *NEUTRON\_ADMIN\_PASSWORD*

  password for connecting to neutron in admin context

- **--neutron-admin-tenant-name** *NEUTRON\_ADMIN\_TENANT\_NAME*

  tenant name for connecting to neutron in admin context

- **--neutron-admin-username** *NEUTRON\_ADMIN\_USERNAME*

  username for connecting to neutron in admin context

- **--neutron-auth-strategy** *NEUTRON\_AUTH\_STRATEGY*

  auth strategy for connecting to neutron in admincontext

- **--neutron-controller-addr** *NEUTRON\_CONTROLLER\_ADDR*

  openflow method:address:port to set controller ofovs bridge

- **--neutron-url** *NEUTRON\_URL*

  URL for connecting to neutron

- **--neutron-url-timeout** *NEUTRON\_URL\_TIMEOUT*

  timeout value for connecting to neutron in seconds

- **--noexplicit-drop**

  The inverse of --explicit-drop

- **--noinstall-lldp-flow**

  The inverse of --install-lldp-flow

- **--noobserve-links**

  The inverse of --observe-links

- **--nouse-stderr**

  The inverse of --use-stderr

- **--nouse-syslog**

  The inverse of --use-syslog

- **--noverbose**

  The inverse of --verbose

- **--observe-links**

  observe link discovery events.
