CRC and frame errors on single interface

two serial ports linked together with a 2048k circuit. one of the CRC interfaces is incrementing CRC, frame and abort errors, the other interface only increments the ' output buffers swapped out' counter. Ping testing from both ends has been performed but no errors seen. Could it be a configuration problem? rate-limiting is in use.

Re: CRC and frame errors on single interface

If CRC errors or frame errors are constantly increasing on the interface, this usually indicates a hardware problem. An exception to this is when CRC and frame errors are found on channelized interfaces - they can indicate clocking problems as well. The fault that is causing the errors can be anywhere between two connected interfaces - on cables, intermediate devices, or on interfaces themselves. Troubleshooting techniques differ slightly for different interface types, refer to these documentation to troubleshoot your errors:
