The show statistics ethernet [port] command provides detailed port statistics, including packet counts, errors, and specifically Cyclic Redundancy Check (CRC) errors.
Why Other Commands Don't Work:
B. show interfaces brief ethernet 1/1/1: This provides a summary of interface status but does not include detailed error information like CRC errors.
C. show mac-address ethernet 1/1/1: This displays MAC address table entries for the specified port, unrelated to error statistics.
D. show port security ethernet 1/1/1: This shows port security configurations and violations, not errors like CRC.
