Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 145

After you connect a host to switch port G0/1, the port error disabled. Which command can you enter to determine the reason?

Answer options

• A. show log
• B. show run interface g0/1
• C. show interfaces g0/1 status
• D. show ip interface brief

Correct answer: A

Explanation

The command 'show log' displays system messages, including those related to port status changes, which will help identify why the port was error disabled. The other commands do not provide specific logs or reasons for the port's state; they focus on configurations or current interface status without historical context.
