Why is my Cisco Network Router having poor performance or excessive errors?
- SSarah NealJul 31, 2025
Poor performance or excessive errors in your Cisco Network Router can stem from a duplex autonegotiation mismatch. Refer to the switch software configuration guide to identify and resolve these mismatches. Alternatively, check if cabling distance is exceeded or if port statistics reveal excessive frame check sequence (FCS), late-collision, or alignment errors. For 10/100BASE-TX connections, ensure the distance between the port and the device is within 328 feet (100 meters). For SFP module port connections, adhere to SFP module cabling guidelines. Reduce cable length if needed and consult your repeater or SFP module documentation for specific cabling guidelines.
