Description (partial)

Symptom:
The COPP per interface policy feature has following limitation:

The TCAM entry maximum for per interface per protocol is 256. After the threshold is exceeded, a fault will be raised. For more information, see:

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/4-x/security/b-Cisco-APIC-Security-Configuration-Guide-411/b-Cisco-APIC-Security-Configuration-Guide-411_chapter_01001.html

This enhancement request is to have a CLI command to display the number of  required ACLs/TCAM entries for the COPP policy that is applied on a per-interface level. The command should possibly display whether the configuration will succeed or not based on the current overall TCAM usage.

Conditions:
This is an enhancement to display the PPPI COPP TCAM usage.
