  • Docker container that runs a Netconf server. Follow the instructions posted How to build and run ODTN Emulators?
  • netconf-console tool that is a simulation tool for Netconf client.
  • "target-output-power" node defined in "openconfig-terminal-device.yang" as the operation target node.
  • Running ONOS instance that is able to configure power through two ways.

Assume that we have started an OpenConfig Cassini Emulator which runs a Netconf server in docker as follows:

Code Block

CONTAINER ID        IMAGE                         COMMAND                  CREATED             STATUS              PORTS                                      NAMES

2. Perform Operations

2.1 Config Power by using Netconf tool like netconf-console

So we use the command listed below to send RPC request to the container:

...

The root node of "openconfig-platform.yang" is "<components>" and its sublist "<component>" contains "<name>" node as its identity. Besides "openconfig-terminal-device.yang" adds node "<optical-channel>" into "<component>" node. "<target-power-config>" is defined as a child node of "<optical-channel>".

2.1.1 Perform <get> Operation

If you want to get the whole components, the content of get-components is:

          </config>
        </optical-channel>

2.2 ONOS startup and node discovery

This section is the environment for section 2.3 and 2.4.

Firstly, an ONOS instance is started via command "bazel run onos-local -- clean". Secondly, the docker container connects to ONOS via command "onos-netcfg localhost device.json". The content of device.json is:

Code Block
{
  "devices" : {
    "netconf:127.0.0.1:11002" : {
      "basic" : {
        "name":"cassini2",
        "driver":"cassini-ocnos"
      },
      "netconf" : {
        "ip" : "127.0.0.1",
        "port" : "11002",
        "username" : "root",
        "password" : "root",
        "idle-timeout" : "0"
      }
    }
  }
}

Then, we use "onos localhost" to log into ONOS CLI environment and see if the docker container is detected.

2.3 Config Power by using ONOS CLI Command "power-config"

An ONOS command is provided to configure the power of line-side ports.

In ONOS CLI environment, the description for command "power-config" is listed:

Code Block
onf@root > help power-config                                                                                                                                         11:56:39
DESCRIPTION
        onos:power-config

    Get/Edit the target-output-power for specific optical-channel

SYNTAX
        onos:power-config [options] operation connection point [value]

ARGUMENTS
        operation
                Netconf Operation including get, edit-config, etc.
                (required)
        connection point
                {DeviceID}/{PortNumber}
                (required)
        value
                target-output-power value. Unit: dBm

OPTIONS
        --help
                Display this help message
        -j, --json
                Output JSON


This command also supports auto-completion function for each parameter.

Currently, only get and edit-config operations are supported:

Code Block
onf@root > power-config                                                                                                                                              11:56:43
get             lock            unlock          get-config      copy-config     edit-config     kill-session    close-session   delete-config

2.3.1 Perform <get> Operation

Through power-config command, you can get the power value of any line-side port of any optical device, for example,

Code Block
onf@root > power-config get netconf:127.0.0.1:11002/216                                                                                                              11:56:43
The target-output-power value in port 216 on device netconf:127.0.0.1:11002 is -2.


2.3.2 Perform <edit-config> Operation

Through power-config command, you can modify the power value of any line-side port of any optical device, for example,

Code Block
onf@root > power-config edit-config netconf:127.0.0.1:11002/216 -4                                                                                                   12:04:11
onf@root > power-config get netconf:127.0.0.1:11002/216                                                                                                              12:06:01
The target-output-power value in port 216 on device netconf:127.0.0.1:11002 is -4.
