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.

From the line "login authentication local" we know that the router uses the local database for authentication so the password should be "Cisco".
Note: "... password 0 ..." here means unencrypted password.
