show ip traffic drop error increasing

[rsamuel37]

Can anyone give me any insight into this error?:

xxx>sho ip traffic | inc encapsulation

Drop: 36177634 encapsulation failed, 109 unresolved, 0 no adjacency

This error is increasing...

Encapsulation failure happens when the router can't resolve a IP to a mac address..

So hhen you see encapsulation failed counter increasing it would most likely be because the router did not receive arp replie to some arp requests, so the packets were discarded.
