Which Command to Use for NAT Traffic Hits Counter?

A

The correct command to display the hits counter for NAT (Network Address Translation) traffic on a Cisco router or switch is A. show ip nat statistics.

Here's a detailed explanation of each option:

A. show ip nat statistics: This command displays the NAT statistics for each translation entry, including the number of hits (i.e., the number of times the translation entry has been used) and the number of misses (i.e., the number of times a translation entry was not found). The output also shows the current NAT configuration and the number of active translations.

B. debug ip nat: This command enables debug messages for NAT on the router or switch, which can help troubleshoot issues with NAT configuration or operation. However, it does not display the hits counter for NAT traffic.

C. show ip debug nat: This command displays the debug settings for NAT on the router or switch, but it does not display the hits counter for NAT traffic.

D. clear ip nat statistics: This command clears the NAT statistics for all translation entries, resetting the hit and miss counters to zero.

Therefore, the correct answer is A. show ip nat statistics.
