we have a open stack cloud created using tripleo. We are getting mirror traffic on our one of VM instance. This mirror traffic will get received on VM if its normal IP packet but when any packet has DSCP marking packets are dropped on bridge interface and after that all traffic is blocked. Not getting any clue why does this happening.

After trying with QoS policy on the port we still see same behaviour. openstack network qos policy create dscp-marking-for-46 openstack network qos rule create --type dscp-marking --dscp-mark 46 dscp-marking-for-46 openstack network qos rule list dscp-marking-for-46 openstack network qos rule show dscp-marking-for-46 d81b3ed3-3a80-4e7b-b16a-0f0743881124

anyone has any idea why this is happening. Thanks in advance.

These are not actual SCTP session. I have a tool which generates packets and forwards with gateway marking IP address of VM interface. Like something we run a PCAP file using TCPReplay tool on linux. Yes the sequence of packets has to be intact otherwise the behavior of server is malfunctioning,

I'm naive to openstack world so this might be a trivial question or might be easy to solve but I don't have any clue of this so please guide me resolve this problem. http:// (image description) I have Baremetal setup created using pike version of openstack OOO. From a VM on Compute-2 generating packets and forward towards VM on Compute-0. In packet capture it is clearly visible that packets coming on Compute-0 NIC interface are in correct order but on the next hop of OVS-Br packets are getting out of sync. I looked on google for any this type of issue is being reported but I wont get any answer for it.

I have highlighted the packet which is out of sync in second trace.

I'm not able to upload any file as I have just created account and I don't have '>10 points required to upload files'

Please help me to identify if I did any miss-configuration or anything. Thanks in advance.
