Re: [ODL Discuss] #opendaylight-help-openflow #opendaylight #help
Hi Luis, I had a look at the document and it seems to be very informative and gives examples of REST and RPC commands. I kind of figured that this would be the solution. I was under the impression that the config datastore contained what was learnt by the controller. I might be wrong as I am new to SDN. Would adding a flow manually on a vswitch automatically push a config to the controller config store? I tried this but the config store is still empty. When I delete a flow on a switch using Mininet command (sh ovs-ofctl del-flows s1 -O OpenFlow13) it does not learn automatically from the controller. Is this normal? I can add a flow manually and it works. Thanks for the very informative answers which has cleared some doubts. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [ODL Discuss] #opendaylight-help-openflow #opendaylight #help
Hi Luis, Apologies, I am very new to this. Could you provide specific instructions on how I could delete an entire openflow table from a switch? How can I use the xml example from the website? Thanks. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[ODL Discuss] #opendaylight-help-openflow #opendaylight #help
[Edited Message Follows] I am using Opendaylight Carbon (also tried Oxygen) with Mininet. I created a small network which conects to the remote ODL Controller using OpenFlow 1.3 using Virtual machines (Ubuntu 18.04) on the same subnet and the mininet hosts can ping each other as expected. When connecting to the controller using a browser, I can login with default credentials and view the topoogy and Nodes using a web UI. Yang shows various properties of which very few gives a response from the controller. Problem: When sending the GET request: *http://ip_address:8181/restconf/config/opendaylight-inventory:nodes/* I get an error message: *"Request could not be completed because the relevant data model content does not exist"* My objectives are to: 1) get the controller to send a message to the switches to clear their flow tables 2) get the controller to send a message to the switches to modify their flow tables Any advice will be really appreciated. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [ODL Discuss] How can I change my topology using RESTCONF commands?
Hi Carlos, I am trying to do the exact same thing and would really appreciate your help. Would you mind sending your full code to me so that I can delete flows from the flow table? By all means I will include your name in my work if you like. I would really appreciate it if you could help me with this. Thanks. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

I need this to work in order to write a Python program to clear flow tables. Any advice will be appreciated. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
