openconfigd is software which manages OpenConfig common data models for networking. It handles networking protocol configuration of switch, router, DNS, DHCP, NAT and Firewall.

openconfigd reads YANG model definition then generate configuration schema from it.

Below command install openconfigd and cli_command to $GOPATH/bin.

$ go get github.com/coreswitch/openconfigd/openconfigd
$ go get github.com/coreswitch/openconfigd/cli_command

CLI command build and set up.

$ cd $GOPATH/src/github.com/coreswitch/openconfigd/cli
$ ./configure
$ make
$ sudo make install

will install cli command to /usr/local/bin.

CLI completion file another cli file exists under bash_completion.d. On Ubuntu, this file should be installed under /etc/bach_completion.d

$ cd $GOPATH/src/github.com/coreswitch/openconfigd/bash_completion.d
$ sudo cp cli /etc/bash_completion.d/

Invoke openconfigd, then start cli. "show version" display version information.

$ openconfigd &
$ cli
ubuntu>
ubuntu> show version
Developer Preview version of openconfigd

openconfigd takes YANG module names as arguments. When no YANG module is specified, default coreswitch.yang is used. '.yang' suffix is optional. Use can specify multiple YANG file. So

$ openconfigd lagopus ietf-ip

will load both lagopus.yang and ietf-ip.yang modules.

There are several other options.

• -c, --config-file= active config file name (default: coreswitch.conf)
• -p, --config-dir= config file directory (default: /usr/local/etc)
• -y, --yang-paths= colon separated YANG load path directories
• -2, --two-phase enable two phase commit
• -z, --zero-config do not save or load config other than openconfigd.conf
• -h, --help Show this help message

-c option specify active config file name. -p option specify config file save directory. When full path is specified to -c option's base directory overrides the -p option config file directory.

-y option specify YANG file load path. Use can specify multiple YANG load path with colon separated list.

-2 option enables two phase commit. It send validate start and end message to protocol modules.

When -z option is specified, only openconfigd.conf file is loaded on start up. Configuraion is never saved to the config file.

$ openconfigd -y /usr/shared/yang:/opt/yang

will search both /usr/shared/yang and /opt/yang directory. Default YANG load path $GOPATH/src/github.com/coreswitch/openconfigd/yang is automatically added.

openconfigd support CLI scripting. All operational and configuration mode commands can run from script.

Here is an example:

#! /bin/bash

source /etc/bash_completion.d/cli

show version
