On SDA edge device, packets' checksum were not updated and resulted packets being dropped on next L3 hop.
All 4 conditions need to be met in order to to see the problem: 1. This happens only on SDA edge device 2. Packets are remarked due to a remarking policy attached to an ingress physical interface or a SVI interface 3. Packets are switched instead of routed due to the destination is in the same subnet. 4. software is running with 16.8.1 or later releases
Remove the QOS policy from the interface so that DSCP value won't be changed. If remarking is needed, policy may be attached to egress direction. If queuing is needed, packet should be marked before entering the switch.
The bug is applicable to 3850, cat9300, cat9400 and cat9500 running releases 16.8.1 or later
