List at least three things to check when troubleshooting Layer 1 problems.
Check for bad cables or connections:
- Use a cable tester to verify that the cable from the source interface is properly connected and is in good condition.
- When you doubt a cable’s integrity, swap the suspect cable with a known working cable.
Make sure that the correct cabling standard is adhered to throughout the network:
- Verify that the proper cable is being used for the connection.
Check that devices are cabled correctly:
- Verify that all cables are connected to their correct ports or interfaces.
Verify proper interface configurations:
- Check that all switch ports are set in the correct VLAN and that spanning-tree, speed, and duplex settings are correctly configured.
- Confirm that any active ports or interfaces are not shut down.
Check operations statistics and data error rates:
- Use Cisco show commands to check for statistics such as collisions, input, and output errors.
- The characteristics of these statistics vary depending on the protocols used on the network.
