My topology is as follow: [cid:[email protected]] DPDK pktgen is used to send packet in my test. In the test process, I found that the packet size can not exceed 978 bytes. If the packet size is larger than 978 bytes, the packet that was sent by pktgen on server 3 can not reach to server 4, the traffic between server 3 and server 4 was blocked. >>>> Can you please confirm whats the MTU value for each interfaces?? >>>>> If the MTU value is sufficient enough, can you please check the“sudo >>>>> ovs-appctl dpctl/show –s” output to know at which interface the packets >>>>> getting dropped Does anybody know why? Thanks. Leo
