A network administrator observes an elevated count of CRC errors on a switchport over the recent weeks. Extensive testing has confirmed the integrity of the transmission medium and the connected hardware's operational status. What should the administrator investigate NEXT to address the increasing error count?
Review the configuration for potential mismatches between the switchport and the endpoint's communication parameters.
Check for possible packet loss across the same link, which may be contributing to the errors.
Examine environmental factors around the switch for possible electromagnetic interference.
Perform a software update on the switch to the latest firmware version.
