Hi experts, I recently integrated vpp stack 21.06 and am running my NAS TCP protocol test cases. The pcap dispatch trace that I captured shows the TCP SYN packets are coming to tcp-input() and then to tcp-listen() but from here pkts are dropped instead of going to tcp-output() graph nodes for sending the SYN-ACK
NOTE ========= The session layer is enabled and the TCP listen IP/port is also showing in the session verbose command. The same test case used to work fine in the VPP 20.05. Am I missing anything? Let me know if there is anything I need to look at. vpp# show session verbose Connection State Rx-f Tx-f [0:0][T] 30.30.30.30:1234->0.0.0.0:0 LISTEN 0 0 Thread 0: active sessions 1 Thread 1: no sessions
