openflowplugin
Following should be installed:
odl-openflowplugin-southbound odl-openflowplugin-flow-services odl-openflowplugin-nsf-services odl-openflowplugin-nsf-model feature:install odl-openflowplugin-flow-services-rest
Then the end-to-end tutorials here should work: https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:User_Guide
All in one:

Set Log Level

log:set DEBUG org.opendaylight.openflowplugin.learningswitch.multi.LearningSwitchManagerMultiImpl karaf@root> log:set LEVEL mypackage.subpackage
This will set the logging for that specific package to whatever the level you provide.
In Karaf 3.x, you can also filter for a specific package using the following command:
karaf@root> log:get mypackage.subpackage
Add Feature Repo
feature:repo-add <url or short name> ?<version> feature:repo-all mvn: repo-add mvn:de.dailab.nemo.dmm/features-dmm/1.0.0-SNAPSHOT/xml/features feature:install dmm-task-all
Auto Import New Bundle
dev:watch is replaced by bundle:watch
or system:property
bundle:list | grep bundle xx abdc
Karaf 3.0:
With this command you can define maven url’s which are be observed by Karaf after you have installed a bundle.
bundle:install -s mvn:ch.dropbit.test/cxf-rest-test/0.0.1-SNAPSHOT bundle:watch mvn:ch.dropbit.test/cxf-rest-test/0.0.1-SNAPSHOT
Afterwards each maven build (mvn clean install) triggers a cxf-rest-test bundle reload. If you want to remove an observation use something like:
bundle:watch --remove mvn:ch.dropbit.test/cxf-rest-test/0.0.1-SNAPSHOT bundle:watch mvn:groupid/artifactID/version
It will actually monitor all bundles that have a location matching mvn:* that have '-SNAPSHOT' in their url.

1. Quick build for dev
Mininet
mn --topo single,3 --mac --switch ovsk,protocols=OpenFlow13 --controller remote,ip=10.10.11.44,port=6653
python:
Mininet CLI
h1 ping h2 switch s1,s2 start
Help
Documented commands (type help <topic>):
========================================
EOF gterm iperfudp nodes pingpair py switch
dpctl help link noecho pingpairfull quit time
dump intfs links pingall ports sh x
exit iperf net pingallfull px source xterm
You may also send a command to a node using:
<node> command {args}
For example:
mininet> h1 ifconfig
The interpreter automatically substitutes IP addresses
for node names when a node is the first arg, so commands
like
mininet> h2 ping h3
should work.
Some character-oriented interactive commands require
noecho:
mininet> noecho h2 vi foo.py
However, starting up an xterm/gterm is generally better:
mininet> xterm h2
ODL Rest

Event Subscription with Rest
Create Subscription from Postman
POST /restconf/operations/sal-remote:create-data-change-event-subscription HTTP/1.1 Host: 192.168.201.43:8080 Authorization: Basic YWRtaW46YWRtaW4= Content-Type: application/xml Accept: application/xml Cache-Control: no-cache <input xmlns="urn:opendaylight:params:xml:ns:yang:controller:md:sal:remote"> <path xmlns:a="urn:opendaylight:inventory">/a:nodes</path> <datastore xmlns="urn:sal:restconf:event:subscription">CONFIGURATION</datastore> <scope xmlns="urn:sal:restconf:event:subscription">BASE</scope> </input>
The response has the Websocket Stream location:
<output
xmlns="urn:opendaylight:params:xml:ns:yang:controller:md:sal:remote">
<stream-name>opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE</stream-name>
</output>
Request a Socket to the Stream
GET /restconf/streams/stream/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE HTTP/1.1 Host: 192.168.201.43:8080 Authorization: Basic YWRtaW46YWRtaW4= Content-Type: application/xml Accept: application/xml Cache-Control: no-cache
The Stream socket is contained in Response header:
Content-Length → 0 Location → ws://192.168.201.43:8185/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE Server → Jetty(8.1.14.v20131031)
Open Connection to the Stream with a Websocket Client (java, chrome plugin)
Using the socket returned above:
ws://192.168.201.43:8185/opendaylight-inventory:nodes/datastore=CONFIGURATION/scope=BASE
Make Some Changes to the Nodes Database
POST /restconf/config HTTP/1.1

Sample notification websocket with Restangular
Note: network topology path
Request the Stream:
We request the stream from the controller by making a POST HTTP request to the data change subscription URL for OpenDaylight:
url = baseURL + 'operations/sal-remote:create-data-change-event-subscription'
headers = ...
payload = '<input xmlns="urn:opendaylight:params:xml:ns:yang:controller:md:sal:remote"> \
<path xmlns:a="urn:TBD:params:xml:ns:yang:network-topology">/a:network-topology</path> \
<datastore xmlns="urn:sal:restconf:event:subscription">OPERATIONAL</datastore> \
<scope xmlns="urn:sal:restconf:event:subscription">SUBTREE</scope> \
</input>'
responseData = requests.post( url, data=payload, headers-headers, auth=... )
streamName = responseData.text
Look the path up in Restconf service:
