Dear all,

I have some questions about RESTCONF and Netconf device. It will be really appreciate if you can give me some hints.

I followed https://wiki.onosproject.org/display/ONOS/NETCONF this website and installed the Mininet machine with of-config installed.

The Netconf device is connected with my ONOS (1.14)successfully, and i can also see it from the ONOS GUI.

onos> devices

id=netconf:192.168.1.101:830, available=true, local-status=connected 8s ago, role=MASTER, type=VIRTUAL, mfr=Of-Config, hw=VirtualBox, sw=1.0, serial=1, chassis=0, driver=ovs-netconf, ipaddress=192.168.1.101, locType=none, name=netconf:192.168.1.101:830, port=830, protocol=NETCONF

As you can see, the device's name is netconf:192.168.1.101:830.

I used the RESTCONF URL: http://127.0.0.1:8181/onos/restconf/data/devices/device= netconf:192.168.1.101:830

Unfortunately i got the resource not found error ...

error

error-type "protocol"

error-tag "invalid-value"

error-app-tag "handleGetRequest"

error-path "devices/device=netconf:192.168.1.101:830"

error-message "Resource not found"

I already activated all the related modules by org.onosproject.openroadm.

What I want to do is just getting the basic information from the netconf device, but always resource not found .

I do not know why this happened ...Did I miss some steps before I used the GET?

One more questions is that , this URL http://127.0.0.1:8181/onos/restconf/data/devices/device= netconf:192.168.1.101:830

can help me get the information of the netconf device whose name is netconf:192.168.1.101:830. If i want to get the information of all the connected netconf devices, what URL should I use? I tried http://127.0.0.1:8181/onos/restconf/data/devices but failed...

Thanks

Best wishes

Hi,

Could you please set the log level to DEBUG, and then try again RESTCONF GET device? This way, RESTCONF will print full exception trace (if there are any) to karaf.log. Please send us the karaf.log.

log:set DEBUG org.onosproject.protocol.restconf.server.rpp.RestconfWebResource

log:set DEBUG org.onosproject.restconf.utils.RestconfUtils

Thanks,

Henry

Dear Henry Yu

This is the log when the netconf device is connected and after I sent the RESTCONF GET

2018-08-08 23:24:39,818 | INFO | nos-topo-build-3 | TopologyManager | 134 - org.onosproject.onos-core-net - 1.14.0.SNAPSHOT | Topology DefaultTopology{time=4390778102921, creationTime=1533795879817, computeCost=116935, clusters=1, devices=1, links=0} changed

Anything wrong with this log??I still got 404 error after RESTCOF GET

I download the Mininet machine with of-config installed from https://wiki.onosproject.org/display/ONOS/NETCONF

Thanks

Hi, This log does not show any errors. Did you see any logs after the following line, or was this the last line in the log ?

Thanks,

Hi,Henry

2018-08-09 16:18:42,564 | INFO | nos-topo-build-6 | TopologyManager | 134 - org.onosproject.onos-core-net - 1.14.0.SNAPSHOT | Topology DefaultTopology{time=19128393345137, creationTime=1533856722562, computeCost=243851, clusters=1, devices=1, links=0} changed

I tried again, and the same log was shown.

It is the last line of the log after I used RESTCONF GET. So i am confused about that.

Actually before I try to get information from Netconf devices:

I followed https://wiki.onosproject.org/display/ONOS/Open+ROADM+MSA to start RESTCONF

When I use this RESTCONF URL http://127.0.0.1:8181/onos/restconf/data/org-openroadm-network:network I got a 404 resource not found error.

After I post http://127.0.0.1:8181/onos/restconf/data,

{

"org-openroadm-network:network": {}

}

and get http://127.0.0.1:8181/onos/restconf/data/org-openroadm-network:network again, it worked.

So, maybe this time, although I already have a netconf device connected, I still need to post something at first(Write a top level device object first?).But I dont know how to do that.

I saw the reply you gave to other people in https://groups.google.com/a/onosproject.org/forum/#!topic/brigade-dynconfig/9w_F0Wwy9BE

we need to Put /onos/restconf/data/devices/device=xyz

{

“device-id” : “xyz” < - - I don’t know the device yang model. I am just making an example.
"device" : "netconf:127.0.0.1:8301"
}

to create a datanode.

The device I used is Mininet machine with of-config installed which is download from onos netconf tutorial.

My netconf device's name is netconf:192.168.10.111:830, but what is the "device-id " i shoud fill in?

Thank you so much for help

best wishes
