Why each option
To display statistics for the control plane policing (CoPP) policy map and aid in troubleshooting, the show policy-map control-plane command is used. This command provides detailed information about traffic matching and actions taken by the CoPP policy.
show control-plane CoPP is not a standard Cisco IOS/IOS-XR command for displaying CoPP policy map statistics.
show control-plane provides general information about the control plane but does not offer the detailed policy map statistics required for troubleshooting CoPP.
The show policy-map control-plane command specifically displays the configuration and statistics for the Quality of Service (QoS) policy map applied to the control plane. This output includes match counters, drop counters, and applied actions for different traffic classes, which is crucial for verifying CoPP operation and troubleshooting issues related to control plane traffic.
show policy control-plane is not a standard Cisco IOS/IOS-XR command for displaying CoPP policy map statistics; the correct keyword is policy-map.
