Which CLI command will reset the IPS pattern matcher statistics?

The command that correctly resets the IPS pattern matcher statistics is "ips pmstats reset." This command is specifically designed to clear the current statistics related to the Pattern Matcher, allowing administrators to refresh the data collected from the Intrusion Prevention System (IPS) without needing to clear the entire system or restart any processes.

Resetting the IPS pattern matcher statistics can be important for troubleshooting and performance monitoring. By refreshing these statistics, you can ensure that you are working with the most up-to-date information regarding how the IPS is functioning and responding to network threats. This helps in assessing the efficiency of the IPS in detecting and mitigating malicious activity.

The other options do not correspond to valid or effective commands for resetting these particular statistics. Each of those commands either uses incorrect syntax or refers to functions that do not specifically address the need to reset the pattern matcher statistics, making them less suitable for the task at hand.
