2015-10-16 03:24:05 -0700 asked a question ODL Karaf log understanding

Hi Expert, Please anyone tell me how to understand the karaf log, i see lot of messages if i enable TRACE (openflowplugin module) also maximum only 10 files are creating, and the old logs are getting deleted (but anyhow i have changes the file size in cfg file). But i am unable to understand whats happening by seeing log.

Please tell, if any other way how to interpret these log messages? How to disable multipart message logs?

Thanks in Advance!!!!

2015-10-14 23:44:09 -0700 commented answer default flow entries installed by ODL when switches get connected

Hi Ashwini, I do not think l2switch module is installing the flow entires, only openflowplugin module is installing. I just uninstalled the l2switch module even then default flow entries are getting installed by openflowplugin module.Please refer this link also for your refrence https://ask.opendaylight.org/question/2184/helium-l2switch-feature/

2015-10-07 02:59:42 -0700 commented answer default flow entries installed by ODL when switches get connected

First Thanks a ton for your comment. I understand about LLDP packetins, but my question is packetin msg about pinging from h1 to h4 as the rule below (you have not mentioned the output CONTROLLER:65535). The exact rule is s2 : in_port:3 --> forward out port 1 and 2 in_port:1 --> forward out port 2 and 3 and CONTROLLER:65535 in_port:2 --> forward out port 3 and 1 and CONTROLLER:65535 My concern is about packetins when i do ping (h1---h4), as per the rule the packet is going to controller also, so for that packetin there is no packet out and no flow-mod is got installed, the ping is happening as it sends to all the ports in the switches. Thanks in Advance!!!!

Hi Experts, Can you please tell me for what purpose ODL installs default flows when switches get connected. Below are the flow entries in each switch. (My config is sw2---sw1---sw3) | | | | h1 h2 h3 h4

Also when i try to ping from h1 to h4 packetin msg is reaching the controller, but no flow mod is installing for that paketin, also ping is successful.

My questions,

  1. what happen to that packetin? (lot of packetin msg are reaching the controller but no response from controller side)
  2. In the flow entry above packets are flooding to all the other port expect in_port, wht is the reason to install a flow like that?
