Cat9300 adjacency drops

[lcaruso]

How do I identify the frames/packets being dropped due to no adjacency?

Branch site having problems. I engaged TAC on this but no solution. With built in Wireshark and other advanced capabilities, hoped we could identify which traffic the Cat9300 is refusing to forward across a point to point link. 

Keeps incrementing:

sh ip traffic | in adj
Drop: 0 encapsulation failed, 0 unresolved, 1621097 no adjacency

Need to identify this traffic to rule it out as a potential cause of the performance. Bandwidth and ping times are excellent. 

100Mb/s connection highest seen is 15Mb/s. Ping times are 18ms consistently to hub.

Post complete output :

sh ip traffic | in adj

Also provide how is this network connected ? wht is the other side connected ?

00Mb/s connection highest seen is 15Mb/s. Ping times are 18ms consistently to hub. 

Hum means VPN ?
