2017-10-05 14:35:42 -0700 asked a question Wrong topology with extra links on Yang UI with physical switch

Hi, I am using physical switches and ODL Baryllium version. I am using a simple linear topology with 2 switches and two hosts. With these physical switches and hosts, I am getting the wrong topology somehow forming the loops with hosts on YangUI. The hosts at the end somehow get connected to the other switch to form a loop.

My Physical connection is like:

H1 --- S1---S2---H2

whereas on YangUI this topology forms a loop with extra fake links between other switch and host.

  S1

H1 . . H2

  S2

I'd appreciate some help to find the reason behind this.

Thank you

Are there any other settings you had to do from host side? I guess you were using beryllium version?

Hi,

I am new in this field and have started ODL a few days ago. I am using physical switches from Mellanox with OpenFlow 1.3 and cannot see the host. I can see only the switches, links and even OpenFlow-enabled ports in the switch. I found that the switches from other vendors had the similar problem. I have tried their solutions but none of them works for me. Is there something obvious I am missing?

I have been trying almost everything, like installing just odl-l2switch-switch-ui and odl-dlux-all.

Now I am using the basic features like odl-restconf, odl-l2switch-switch, odl-mdsal-apidocs, odl-dlux-all

I have tried installing flows to the switches

Couldn't see any obvious error in karaf.log except while installing feature:l2switch-switch

RevisionSourceIdentifier [name=openflow-plugin-provider-impl@2015-03-27]] org.apache.aries.proxy.UnableToProxyException: java.lang.ClassFormatError: Duplicate interface name in class file Proxyc2f995054097420eb9db015ba7e3d68a

Do, I need to configure hosts for ODL controller? Any specific feature or feature order? plugin?

I don't understand why is this a problem only with physical switches?

help please! waiting for reply!

TIA

2017-03-27 05:48:02 -0700 answered a question no host topology(hardware switch)

Which Version of Opendaylight are you using? I am facing the exactly same problem with my hardware switch.

May I know how did you fix this?

I can add flow entries and they can ping each other as well. But cannot see the host node at all.

Please reply if anybody knows the solution.

TIA

2017-03-23 07:09:57 -0700 answered a question HP switch and ODL Beryllium

@Cesar I don't understand, how did you find out these 2 specific flow rules (260 and 37) ? Also, are you using Openflow 1.3 compatible switches? Unfortunately, this method is not working for me :(

You see those rules from the switch openflow flows ? I couldn't see hosts from GUI yet.

Please help, Thanks.

2017-03-14 01:47:07 -0700 answered a question network-topology not show all information

I am facing the same issue with my physical network. Is this related to the physical network? Also, I am unable to see the host information. Did you find any solution?
