What to do if Cisco WS-C2960L-24TS-LL Switch port has many packet errors or constantly flaps?
- JJennifer GrantAug 11, 2025
If a Cisco Switch port has many packet errors or constantly flaps, first, examine or exchange the copper or fiber-optic cable with a known, good cable. Also, check for broken or missing pins on cable connectors. Rule out any bad patch panel connections or media converters between the source and the destination. If possible, try the cable in another port or interface to see if the problem follows the cable.
