2920-24G PoE + with RYU controller

  • 1.  2920-24G PoE + with RYU controller

    Posted Jan 17, 2020 12:21 PM


    I am using the HP switch 2920-24G PoE + in Openflow 1.3 mode with a RYU controller.  I am trying to get a basic topology. I have created 2 VLANS, one vlan for the controller and another for the hosts.

    I am trying to run Ryu controller's example  
    I have worked with RYU controller with other switches, even with mininet and it works perfectly. However with the HP switch 2920-24G PoE switch, it does not work, no message is observed in the RYU controller.  I observe in the switch the controller connection UP, however, the RYU controller does not receive any messege. Could someone help me figure out what the problem is?. Thank you in advance for any information.


    The running configuration is as follows:

    hostname "HP-2920-24G-PoEP"
    module 1 type j9727a
    snmp-server community "public" unrestricted
       controller-id 1 ip controller-interface vlan 1
       instance "of1"
          member vlan 2
          controller-id 1
          version 1.3 only
       no ip address
    vlan 1
       name "DEFAULT_VLAN"
       no untagged 13-24
       untagged 1-12
       ip address
    vlan 2
       name "VLAN2"
       untagged 13-24
       ip address
    The openflow instance information is:

    Can you please how to solve the issue? Also, are the additional configurations required if I use ryu-manager based on openflow1.3?

    I have failed to connect ryu-manager with switches based on openflow1.3.
