Hi all,
When we replace cisco 3900 with ISR4431，there are packets loss in the QoS queue. While it is equal to the total output drops. G0/0/0 is the WAN interface.
Whether there is a problem with configuration?
What is the cause of the loss of packets?
The attachment is the collected information. Thank you !
