While troubleshooting i came across this challenge ,able to see retransmission packets continuously in packet capture . please let me know in what scenarios this retransmission packets are seen.


Generally retransmission packet are seen when upstream connected device reject or drops packet .

When source is initiated traffic towards destination as we know TCP protocol is reliable protocal until aknowledgement is received from destination souce will frequently continuously sends packets towards destination and when this packet is droped in transit before reaching destination then in this scenario retransmission packets are seen.
