Can someone tell me why we get the reliability issue on an interface?

General
1

reliability 255/255 like this if we get this it means no issue but suppose if we get 40/255then what could be the issue

2

60% it will be cabling issue

3

Ok so when we get crc and input errors

4

Input and CRC errrors occured when we have issue in the SFP or local cabling

5

So you mean the reliability and crc errors we get because of cabling issue.
Correct me if I am wrong

To troubleshoot reliability issues on a Cisco interface, you can perform the following steps:

  • Check physical connections and cables for any signs of damage.
  • Verify interface configurations and ensure they match the intended setup.
  • Monitor the interface for errors, collisions, and drops using network monitoring tools.
  • Update the device firmware and software to the latest stable release.
  • Ensure the interface is not overloaded by checking bandwidth utilization.
  • Investigate the network traffic for any unusual patterns or congestion.
  • Conduct power supply checks to ensure stable power delivery to the device.
  • Identify and mitigate sources of external interference.
