Control plan policy test for Cisco routers

1.CoPP and CPPR

Copp--control Plane policing refers to the service that is implemented directly in the control Plane policy

Cppr--control Plane Protection refers to service implemented under the Cef-exception,host,transit three sub-interfaces of control Plane policy

Among them, Copp does not need CEF support, but CPPR need CEF support, if close CEF will have the following prompts:

R2 (config) #no IP CEF

R2 (config) #

*mar 1 00:26:44.431:%cp-4-cppr_disabled:removing security features on host, transit and cef-exception paths

R2 (config) #

*mar 1 00:26:44.447:%cp-5-feature:control-plane policing FEATURE disabled from Control plane host path
