[OPNFLWPLUG-664] Failed to add flows with actions ICMP code and type in OF1.3

Mon, 27 Sep 2021 09:01:47 +0000

I have been testing with Beryllium SR1 distribution for VTN project, and faced issue while adding flows with action ICMP code and type for OF1.3.

That is after adding flows when i verify using dump-flows in mininet actions mod_tp_src and mod_tp_dst are not displayed in OF1.3. But for OF1.0 mod_tp_src and mod_tp_dst are shown in dump-flows.

To cross verify, i have tested the above scenario with Openflowplugin Restconf command and faced same issue. Below are the steps i have followed,

1) Configured mininet with sudo mn --topo tree,2 --controller remote,ip=10.106.138.117 --switch ovsk,protocols=OpenFlow10

2) Add flows with action set-tp-dst-action and set-tp-src-action using below command, and response code is success

3) Checked flowentries in mininet for OF1.0 and actions mod_tp_src and mod_tp_dst are applied in node.
mininet> dpctl dump-flows -OOpenFlow10

I have followed the same above scenario in OF1.3, failed to display flows in mininet.

1)1) Configured mininet with sudo mn --topo tree,2 --controller remote,ip=10.106.138.117 --switch ovsk,protocols=OpenFlow13

2) Add flows with action set-tp-dst-action and set-tp-src-action using below command, and response code is success. Used the same command which i tried for OF1.0, which is above.

3) Checked flowentries in mininet for OF1.3 and but flow is not created. Output is as below,
mininet> dpctl dump-flows -OOpenFlow10

- - s1 ------------------------------------------------------------------------
    NXST_FLOW reply (xid=0x4):

    mininet>

I would like to know is there any issues in adding flows with actions ICMP code and type. Since the scenario which is working for OF1.0.

For your information i have attached karaf.log with TRACE enabled for Openflowplugin.

Attached with of_karaf_log.zip file.
