# Revision history [back]

I have solved the problem by doing this:

• I performed a clean installation of the ODL Beryllium version (instead of Boron that I was using before). I also installed the "odl-l2switch-switch-ui" feature only;

• I changed one property of 58-l2switchmain.xml file from true to "false" (which is inside of <odl-root-folder>/etc/opendaylight/karaf), as follows:

  <is-install-dropall-flow>false</is-install-dropall-flow> (default is true)

• I have also setted two properties of the 54-arphandler.xml to "false", as follows:

  <is-proactive-flood-mode>false</is-proactive-flood-mode>
<is-hybrid-mode>false</is-hybrid-mode>

• I have setted one property of file 52-loopremover.xml to "true", as follows:

  <is-install-lldp-flow>true</is-install-lldp-flow>

• I started the ODL controller: ./bin/karaf (without the -of13 option)

• Finally, I had to install two more rules on ODL (via its REST API and Postman), as follows:

First, one normal-pipeline rule:

http://localhost:8181/restconf/config/opendaylight-inventory:nodes/node/[your-switch-id-here]/table/0/flow/260

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<max-length>65535</max-length>
</output-action>
</action>
</apply-actions>
</instruction>
</instructions>
</flow>

• And a second rule to deal with ARP packets:

After doing all these steps, the controller will now install the following rules automatically for us:

 cookie=0x69, duration=808.580s, table=0, n_packets=26, n_bytes=2012, priority=1 actions=NORMAL,CONTROLLER:65535
cookie=0x2b00000000000003, duration=808.584s, table=0, n_packets=0, n_bytes=0, priority=100,dl_type=0x88cc actions=CONTROLLER:65535
cookie=0x2b00000000000003, duration=808.584s, table=0, n_packets=2, n_bytes=84, priority=1,arp actions=CONTROLLER:65535


Now, all the client-hosts of my topology and the switch appears in the topology GUI view and can ping each other. Regards,

After doing all these steps, the controller you will now install notice that the following rules are automatically for us:installed after the controller is started:

 cookie=0x69, duration=808.580s, table=0, n_packets=26, n_bytes=2012, priority=1 actions=NORMAL,CONTROLLER:65535
cookie=0x2b00000000000003, duration=808.584s, table=0, n_packets=0, n_bytes=0, priority=100,dl_type=0x88cc actions=CONTROLLER:65535
cookie=0x2b00000000000003, duration=808.584s, table=0, n_packets=2, n_bytes=84, priority=1,arp actions=CONTROLLER:65535


Now, From the above rules, the controller now can interact with the hosts. Also, all the client-hosts hosts of my topology and the switch appears will appear in the topology GUI view and can ping each other. Regards,
