I think it's just a typo, but for those who will read this in the future, it is better to fix it:
>CPPr is Control Plane Policing >CoPP is Control protection >CoPP is an extension of CPPr that has host, transit and CEF-exception sub-interfaces. exactly the opposite: CoPP is Control Plane Policing CPPr is Control Plane Protection CPPr is an extension of CoPP that has host, transit and CEF-exception sub-interfaces. with all the consequences.. and good link for reference http://www.cisco.com/web/about/security/intelligence/understanding-cppr.html Best regards, Andrey
