    Sorry I forgot to include the openflow configurations OpenFlow: Enabled
    Versions: OpenFlow10, OpenFlow13
    Mode: Standard
    FDB: On
    Access-list width: Double
    Controller : Primary
    Status : ACTIVE
    Datapath ID : 0000020496987825
    VR : VR-Default
    Mode : out-of-band Active
    Target : tcp:192.168.212.236:6633
    Uptime(secs) : 54314

    configure openflow controller primary out-of-band active ipaddress 192.168.212.236 [/code]What I did here is tagged the controller to the Vlan "Internal" and gave the IP 192.168.212.236. On the controller side, it is able to discover the ports associated with the openflow enabled vlans, however, it does not show any topology and flows.

    Currently, There are no access-list configured in the switches.

    Additional info:
    Here are the openflow tables
    show openflow tables
    table_t_get valid=1, id=0
    table_t_get id=0, first/last=1/3

    Thanks for the information? What type of flow are you trying to push? What controller are you using? how is it configured?

    Are you running a older version of EXOS?
