Hello everyone: I am receiving CRC errors on a remote site router's serial port. I have assumed this to be an issue with our frame-relay provider. But we are also seeing CRC errors on some of the fast ethernet ports in switch behind the router. Is this the result of bad packets being passed from the router to the switch, or could I be looking at two entirely different problems? Also of note is the fact that on the switch ports that are showing CRC errors, they are also showing input errors. I will check the switch stats for CRC errors later, after we have resolved the router's issues, but for now I was just trying to determine if the two are related. Thanks.
