As of recent, I am experiencing a weird problem on one of my router interfaces. About once a day, I cannot access it via the IP address. A traceroute will fail at it as well. When I console in and check the status, I am seeing that it is up/up. There are no entries in log to indicate any bouncing. The rxload/txload are both at 1/255. However, I am showing packets as being dropped in the output queue when I do a "sh int summ". This is a fast ethernet interface on an older router. I have swapped out cables thinking maybe it was a cable issue. The interface is set to full duplex. Is it possible the link is being saturated and that is the cause for the packet drop? If I do a shut/no shut to bounce the port, everything is resolved and I can then log in using the IP on the interface and it will respond to traceroute. Any ideas?
