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 ?
