What command instructs the device to timestamp Syslog debug messages in milliseconds?
Click on the arrows to vote for the correct answer
A. B. C. D.B
The correct command to instruct the device to timestamp Syslog debug messages in milliseconds is B. "service timestamps
The correct answer to the question is option D: "service timestamps log datetime msec."
In Cisco devices, the "service timestamps" command is used to enable timestamping of various log messages, including Syslog debug messages. This command allows administrators to record the time at which events occur in the device's logs, making it easier to troubleshoot network issues.
The "service timestamps log" part of the command specifies that the timestamps should be added to the log messages. The "datetime" parameter indicates that the timestamps should include both the date and time information. The "msec" parameter specifies that the timestamps should include milliseconds as well.
Here is a breakdown of the options and why they are incorrect:
A. Option A, "service timestamps log datetime localtime," is incorrect because it does not include the "msec" parameter, which is required to timestamp the messages in milliseconds.
B. Option B, "service timestamps debug datetime msec," is incorrect because it specifies the "debug" keyword instead of "log." The "debug" keyword is used for debugging messages, not Syslog debug messages.
C. Option C, "service timestamps debug datetime localtime," is incorrect because it also specifies the "debug" keyword instead of "log," and it does not include the "msec" parameter.
Therefore, the correct command to instruct the device to timestamp Syslog debug messages in milliseconds is "service timestamps log datetime msec" (option D).
