Openflow ACL-configuration

[Christian_Matir]

Good day,
I am trying to configure Openflow on 4 x670 stack. I simply followed the instructions according to the documentation and have successfully installed Openflow. however, it returns the following error.

11/21/2017 20:20:26.24 Slot-1: 04181|ofproto_exos|WARN|No context returned from ACL manager (cmd=0x3002), likely when port is removed

Any tips on what the next step should be is highly appreciated.

Thanks in advance

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?

Sorry I forgot to include the openflow configurations OpenFlow: Enabled

configure openflow controller primary out-of-band active ipaddress 192.168.212.236 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

Can we see your openflow config?
