Congure Control Plane Policing
You can create a CoPP service policy on a per-protocol and/or a per-queue basis that serves as the system-wide conguration for ltering
and rate limiting control-plane trac.
Conguring CoPP for Protocols
This section describes how to create a protocol-based CoPP service policy and apply it to control plane trac.
To create a protocol-based CoPP service policy, you must rst create a Layer 2, Layer 3, and/or an IPv6 ACL rule for specied protocol
trac. Then, create a QoS input policy to rate-limit the protocol trac permitted by the ACL. Associate the ACL and QoS policy for each
protocol in a QoS input policy-map and apply the complete protocol-based rate-limiting conguration to control-plane trac.
For complete information about creating ACL rules and QoS policies, see Access Control Lists (ACLs) and Quality of Service (QoS).
