5.4 Debugging Ping and Tracert

This section describes how to locate faults through ICMP messages.
Context
Debugging affects the performance of the system. After debugging, run the undo debugging
all command to disable it immediately.
If you run the ping or the tracert command on the two S9300&S9300Es but the ping or tracert
operation fails, you can run the following command respectively on each S9300&S9300E to
further locate the fault after confirming that the physical link between the two
S9300&S9300Es is normal.
Procedure
Step 1 Run the debugging ip icmp command to enable ICMP packet debugging.
Through this command, you can check the transmission of ICMP messages during the running
of the ping or tracert the command and thus locate which device fails.

5.5 Configuration Examples

This section provides a configuration example of ping and tracert operations.

5.5.1 Example for Performing Ping and Tracert Operations

Networking Requirements
As shown in
the log host. If Switch A and the log host are disconnected, you cannot know which device fails
because there are other network devices between Switch A and the log host. To locate on which
link segment the fault occurs, you can perform ping and tracert operations.
