Note: DON'T USE CTRL-D to quit. That fails to clean up gracefully. Best practice is to use "shutdown -f". Note: Building will run karaf which will fail if another instance is already running. It also touches/creates files in v3po/karaf... See #5 below for clean up recipe. 5) Testing with YANGUI - DOESN'T WORK WITH FIREFOX! :-( - Install google chrome. - Start chrome and enter the URL: http://localhost:8080/index.html#/yangui/index - Select "Yang UI" on left region - Expand (click on '+') v3po rev.2015.01.05 - Expand (click on '+') operations - Enter text ("Dave") in textbox next to "me" - Select "Send" - Results show up in "version" textbox: "Yo Dave! VPP interface list is [GigabitEthernet8/0/1: 5, TenGigabitEthernet86/0/0: 6, local0: 0]!" 6) Pre-build clean up - Running karaf as root touches files which will break the build. Do the following to clean up before building: shutdown -f sudo chown -R dwallace:floppy /scratch/dwallace/honeycomb-vpp/v3po/karaf 7) Adding YANG models NOTE: pom.xml dependency versions are managed via specifications. When including standard yang models (e.g. from org.opendaylight.mdsal.model), there needs to be a depencency defined to tell maven what version to download into the local repo. This isw why each dependency in the section does not contain version information. - Add a dependency in .../honeycomb/v3po/api/pom.xml - Add a dependency in .../honeycomb/v3po/features/pom.xml - Add a bundle in ../honeycomb/v3po/features/pom.xml NOTE: Yangtools don't unravel nested import statements, so all imported yang models referenced in v3po.yang must be explicitly imported (e.g. ietf-interfaces) 8) Useful CURL commands for debugging netconf mounts # show mounted nodes curl -su admin:admin http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes?prettyPrint=true;echo # show node configuration curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/config:modules/module/odl-sal-netconf-connector-cfg:sal-netconf-connector/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/config:modules/module/odl-sal-netconf-connector-cfg:sal-netconf-connector/controller-config?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/config:modules/module/odl-sal-netconf-connector-cfg:sal-netconf-connector/vpp1?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/config:modules/module/odl-sal-netconf-connector-cfg:sal-netconf-connector/vpp2?prettyPrint=true;echo # show node connection status curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/controller-config?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/vpp1?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/vpp2?prettyPrint=true;echo # show mount config modules curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node//yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/vpp1/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/vpp2/yang-ext:mount/?prettyPrint=true;echo # show mount config modules curl -su admin:admin -H 'Accept: application/xml' -H 'Content-Type: application/xml' http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node//yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin -H 'Accept: application/xml' -H 'Content-Type: application/xml' http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin -H 'Accept: application/xml' -H 'Content-Type: application/xml' http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/vpp1/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin -H 'Accept: application/xml' -H 'Content-Type: application/xml' http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/vpp2/yang-ext:mount/?prettyPrint=true;echo # show mount operational modules curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node//yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/controller-config/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/vpp1/yang-ext:mount/?prettyPrint=true;echo curl -su admin:admin http://localhost:8181/restconf/operational/network-topology:network-topology/topology/topology-netconf/node/vpp2/yang-ext:mount/?prettyPrint=true;echo 9) Clean up ODL cache/state cd /scratch/dwallace/honeycomb-demo/r2demo/karaf/target/assembly/bin sudo rm -rf ../data/* sudo rm -f ../etc/opendaylight/current/*
