CoPP Questions

If you are not sure about CoPP, please read our Control Plane Policing (CoPP) Tutorial (on networktut.com)

Question 1

Explanation

CoPP protects the route processor on network devices by treating route processor resources as a separate entity with its own ingress interface (and in some implementations, egress also). CoPP is used to police traffic that is destined to the route processor of the router such as:
+ Routing protocols like OSPF, EIGRP, or BGP.
+ Gateway redundancy protocols like HSRP, VRRP, or GLBP.
+ Network management protocols like telnet, SSH, SNMP, or RADIUS.

Therefore we must apply the CoPP to deal with SSH because it is in the management plane. CoPP must be put under “control-plane” command. But we cannot name the control-plane (like “transit”).
