How do I troubleshoot Interface input errors on my Cisco 2651XM Router.
I have a cisco 2651XM Router, and have been recieving input errors on my FA0/0 port. This is my port that connects to MY ISP. Any ideas on how to troubleshoot this? Below is my show interface ouput, for both interfaces on my router. Thanks

OK. I will start by replacing cables. I have contacted my ISP. We both sent each other 10000 pings with a success rate of 100%. It doesn't look to be losing packets.
