Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 30

What debug command is used to identify and troubleshoot IP Fragmentation and Path Maximum Transmission Unit Discovery issues?

Answer options

• A. debug ip icmp
• B. debug ip packet
• C. debug ip policy
• D. debug ip routing

Correct answer: A

Explanation

The command 'debug ip icmp' is specifically designed to provide insights into ICMP messages, which are crucial for identifying issues with IP fragmentation and MTU discovery. The other options, while useful for different aspects of IP routing and policy, do not focus on the ICMP messages necessary for troubleshooting these specific problems.
