Why is my Cisco Catalyst 3550 Switch experiencing poor performance or excessive errors?
- SSteven MullinsJul 26, 2025
Poor performance or excessive errors on your Cisco Switch might be due to a speed and duplex autonegotiation mismatch or exceeding cabling distance limits. To troubleshoot, use the `show controllers ethernet-controller privileged EXEC` command to check port statistics, or the `show interfaces privileged EXEC` command to view port status. Also, verify that the cable length is within the limits specified in the “Front-Panel Description” section.
